We operate the largest and most advanced vacuum truck fleet in Western Australia, and mining sites are one of the sectors we work with most. 

Here is what mining vacuum trucks actually do, the waste streams they handle, and why they have become a standard part of how WA mine sites manage waste.

What Is a Mining Vacuum Truck?

A mining vacuum truck is a heavy-duty vacuum tanker built to remove liquid, sludge or solid material from a site using suction rather than manual digging or pumping. A hose is fed into a sump, pit, tank or excavation, and a powerful vacuum system draws the material into a sealed tank on the back of the truck, ready to be transported and disposed of correctly.

The same core technology used on commercial and civil sites is built out for mining conditions, with higher capacity tanks, more robust hoses and fittings, and trucks capable of working on unsealed roads and remote sites where a standard service vehicle would struggle. 

Some trucks use water to help break down and flush material, known as hydro excavation, while others use vacuum alone to lift dry spoil, known as air excavation. Many mine sites need both, depending on the job.

Why Mine Sites Rely on Vacuum Trucks

Mining generates waste at a scale and pace that most other industries do not, and vacuum trucks are suited to nearly all of it.

Process water and sludge accumulate in sumps and settling ponds and need regular removal to keep operations running. Drill spoils and cuttings build up around exploration and drilling activity and have to be cleared to keep the site safe and workable. 

Wash bays and workshop pits, used to clean mobile plants and vehicles, fill with hydrocarbon-laden water that cannot simply be left or tipped out. And non-destructive digging is routinely used to expose buried services and infrastructure on-site without the risk of striking them with an excavator.

A vacuum truck handles all of these without anyone having to shovel, pump or manually decant the material, which matters on a site where safety around plants, pits and confined spaces is a constant consideration.

The Waste Streams Mining Vacuum Trucks Handle

Different waste types on a mine site call for slightly different handling, and an experienced operator adjusts the approach to suit each one.

How a Vacuum Truck Service Works on a Mine Site

Every mine site job follows a similar sequence, adjusted for the site’s own procedures and access requirements.

We Confirm the Job and Site Requirements

Before mobilising, we confirm what needs to be removed, where it is, and any site-specific inductions, permits or access arrangements the mine requires. Remote sites in particular need this planned in advance so the truck arrives ready to work.

We Remove the Waste With Vacuum Recovery

The truck’s hose is positioned at the sump, pit or excavation, and the material is drawn into the sealed tank. For thicker sludge or compacted material, water assists the process, while dry spoil can often be lifted with suction alone. This keeps the waste contained from the moment it leaves the ground.

We Transport and Dispose of It Correctly

Once collected, the waste is transported off-site and disposed of at an appropriate facility, with different waste types, particularly anything contaminated or hazardous, directed to the right disposal pathway rather than treated as general waste.

Safety on Mine Sites

Safety is not optional on a Western Australian mine site, and it shapes how vacuum truck work is carried out. Operators need to be inducted to the site, follow its specific procedures around plant, traffic management and confined spaces, and work to the standards set out under WA’s mine site safety framework. WorkSafe WA publishes the codes of practice and guidance that govern safety on mining and exploration sites across the state, and vacuum truck work is planned around those requirements rather than around convenience.

Vacuum recovery itself is inherently safer than manual handling for a lot of mine site waste, since the operator controls the hose and truck from a distance rather than working inside a pit, sump or excavation.

Why This Matters for WA’s Mining Sector

Western Australia’s resources sector is enormous, and it underpins a large share of the state’s economy and employment. Sites operate around the clock, often in remote locations, and a delay in clearing a sump or a wash bay can hold up other work on-site. Reliable, on-call vacuum truck capacity is part of what keeps a mine site’s day-to-day operations moving, not just an occasional service.

Why Choose iVac WA

Mining sites need a vacuum truck service that turns up on time, understands site requirements, and handles the waste correctly. Here is what we bring to every job:

• We remove process water, drill spoil, wash bay water and contaminated soil using vacuum and hydro excavation, suited to the material involved.
• We transport waste to the right disposal facility, keeping contaminated and hazardous streams properly separated.
• We work to mine site induction, access and safety requirements as standard.
• We support Western Australia’s mining, industrial, civil and commercial sectors, with a focus on safe work and a fast turnaround.

Frequently Asked Questions

What is a mining vacuum truck used for?

It removes liquid and solid waste from a mine site, including process water and sludge from sumps, drill spoil, wash bay water, and contaminated soil exposed during non-destructive digging, drawing it into a sealed tank for transport and disposal.

What is the difference between hydro and air excavation on a mine site?

Hydro excavation uses water to help break down and flush material before it is vacuumed up, which suits thicker sludge and compacted ground. Air excavation uses vacuum suction alone to lift drier material, which is often preferred where water use needs to be minimised.

Can vacuum trucks work on remote WA mine sites?

Yes. Mining vacuum trucks are built for site conditions, including unsealed roads and remote locations, and jobs are planned around each site’s access, induction and permit requirements in advance.

How often do mine site sumps need to be cleared?

It depends on the site and the volume of water or sludge generated, but sumps, settling ponds and wash bay pits are typically cleared on a regular schedule to prevent overflow and keep operations running smoothly, rather than waiting until they are full.

Is vacuum removal safer than manual digging or pumping on a mine site?

Yes. Vacuum recovery is operated from outside the pit, sump or excavation, which reduces the need for workers to enter confined spaces or handle waste directly, an important consideration under WA’s mine site safety requirements.

Do you handle hazardous or contaminated waste on mine sites?

Yes. Contaminated soil, hydrocarbon-laden wash water and similar waste streams are collected using vacuum recovery and transported to a facility licensed to accept that particular waste type, keeping it separated from general waste.

Conclusion

Mining vacuum trucks have become a standard part of how Western Australian mine sites manage waste, because they clear sumps, drill spoil, wash bay water and contaminated soil quickly, safely and without unnecessary manual handling. 

On a site where schedules are tight and safety requirements are strict, reliability matters as much as the equipment itself.

Whether it is a single sump that needs clearing or an ongoing waste removal arrangement across a site, the right vacuum truck service keeps operations moving.

If you manage a commercial, industrial, civil or mining site, there is a good chance you will need a sucker truck at some point. 

This guide covers what these trucks do, what they can and cannot remove, and what to check before you book one, so you get the right job done properly the first time.

What Is a Sucker Truck?

A sucker truck is a vacuum tanker. A large pump or blower creates suction, a hose draws material from the source, and the waste is held in a sealed tank on the truck until it can be transported to a facility that is licensed to receive it. 

Some trucks also carry a pressure water system, which lets the operator break up compacted sludge or silt before it is drawn away.

The name is colloquial, and you will see providers use “vacuum truck” or “vacuum tanker” on their websites, but the job is the same. Whichever term you use, the value is that the work is done by suction, from a safe distance, without anyone climbing into a pit or lifting heavy buckets of waste.

What Can a Sucker Truck Remove?

These trucks handle a wide range of liquids, sludges and loose solids, which is why they turn up across so many industries.

On commercial and industrial sites, the most common jobs include clearing blocked or silted stormwater pits and pipes, emptying sumps, removing sludge from wash bay and mud pits, and cleaning out settling basins. 

On construction and civil projects, they remove slurry and spoil, and clear drainage during and after earthworks. On mining sites they process water, drill spoil and sump sludge. They are also used to remove spent abrasive blasting media, such as garnet, from blasting enclosures.

When Do You Need a Sucker Truck?

Most sites book a truck for one of two reasons: a routine clean that keeps a system working, or a problem that has already shown up.

Routine cleaning is the cheaper and less stressful path. Stormwater pits fill with sand and sediment over time, wash bay pits build up sludge, and sumps slowly lose capacity. Clearing them on a schedule, ideally before the wetter months in Perth, keeps drainage working and stops small build-ups becoming a flood.

Reactive call-outs are what you do when something has gone wrong. Water ponding in a car park after rain, a pit overflowing, a wash bay backing up, or a sump too full to pump are all signs it is time to book. In an emergency, such as flooding after a heavy downpour, speed matters, so it helps to know who you will call before you need them.

Which Waste Can and Cannot Go in the Tank?

This is where a lot of site managers get caught out. The truck can physically draw up almost anything, but that does not mean everything can legally be dealt with the same way once it is in the tank.

Waste is classified by what it is and where it came from. Some liquid and sludge is straightforward to dispose of, while other material, such as contaminated wash water or sludge carrying hydrocarbons or chemicals, needs to go to a facility licensed to accept it.

In Western Australia, certain wastes are classed as controlled waste, and the Government of Western Australia sets out the controlled waste requirements for anyone transporting them, including licensing and tracking from the point of generation to a lawful disposal facility.

The same thinking applies to the sewer. Not all wastewater from a business can be discharged to it, and the Water Corporation requires a permit before any trade waste is discharged, including wastewater from vehicle or plant servicing. If you are unsure what your site’s waste is classed as, ask before the truck arrives, not after.

What to Check Before You Book a Sucker Truck Provider

Not every provider is the same, and a few quick questions will tell you a lot.

Do They Understand Your Waste Stream?

Tell the provider what you need removed and where it came from. A good operator will ask follow-up questions about contamination, volume and access, because the answers decide the truck, the equipment and the disposal pathway.

Can They Handle the Volume and the Access?

Tank capacity matters. A small truck on a large job means multiple trips and a longer day. Access matters too, since hose length, overhead clearance and ground conditions all affect what is practical on a tight or remote site.

Where Does the Waste Go?

Ask where the waste is taken and whether the provider can supply records of what was collected. If the waste is a controlled waste, ask whether the provider holds the licensing required to transport it. A reputable operator will answer plainly.

Do They Meet Your Site Requirements?

Many commercial, industrial and mining sites require inductions, safety documentation and specific equipment standards before a contractor can start. Raise this early so the job is not delayed on the day.

Can They Respond When It Matters?

If your site is prone to flooding or relies on a wash bay running daily, response time is part of the service. Ask what their emergency availability looks like.

How a Sucker Truck Job Works

A well-run job follows a simple sequence.

First, we confirm what is being removed, where it is, and what access the truck has. Next, the operator positions the truck, sets up the hose and, where needed, uses water to break up compacted material. 

The waste is drawn into the sealed tank, keeping it contained from the moment it leaves the pit or drain. Once the area is clear, we check that it is properly cleaned, and the waste is transported to an appropriate disposal facility. Finally, you receive a record of what was collected, which is useful for site compliance and audits.

Why Sucker Trucks Suit Perth Sites

Perth’s conditions make this work a regular need. Sandy soils wash fine sediment into stormwater pits and pipes with every heavy rain, and a lot of the year’s rainfall arrives in intense winter downpours, so a partly blocked system can be overwhelmed quickly. 

Industrial areas across the metropolitan region, along with the state’s mining sites, also generate steady volumes of wash water, sludge and spoil that need dependable removal.

Why Choose iVac WA

When you book a sucker truck, you want the right equipment, a clear process and a provider who turns up when they say they will. Here is what we bring to every job:

• We operate the largest and most advanced vacuum truck fleet in Western Australia, so we have the capacity for routine cleans and larger jobs.
• We clean stormwater drains, pits and soakwells, car wash and mud pits, and remove garnet waste, wet or dry.
• We provide emergency flood response when heavy rain overwhelms a site.
• We work to your site’s induction, access and safety requirements as standard.
• We support Western Australia’s commercial, industrial, civil and mining sectors, with a focus on safe work and a fast turnaround.

Frequently Asked Questions

What is a sucker truck?

A sucker truck is another name for a vacuum truck or vacuum tanker. It uses powerful suction to draw liquids, sludge and loose material into a sealed tank, so waste can be removed from pits, drains, sumps and excavations without manual handling.

What is the difference between a sucker truck and a vacuum truck?

There is no practical difference. It is the more informal term, and vacuum truck or vacuum tanker is how most providers describe the same equipment.

What can a sucker truck remove?

Water, silt, sludge, slurry, spoil and spent blasting media such as garnet, among other materials. What can then be done with that material depends on what it is and where it came from, which is why the waste type should be confirmed before the job.

Can a sucker truck clear a blocked stormwater drain?

Yes. These trucks, often combined with high-pressure jetting, remove the silt, sand and debris that block stormwater pits and pipes, restoring capacity without excavation.

How often should pits and sumps be cleaned?

It depends on the site, but most commercial and industrial stormwater pits benefit from at least an annual clean, ideally before the wetter months. Wash bay pits and sumps in heavy use may need more frequent attention.

Do you provide emergency sucker truck services in Perth?

Yes. We respond to urgent call-outs, including emergency flood response, when heavy rain overwhelms a site.

Do you service homes?

Our work is focused on commercial, industrial, civil and mining sites across Western Australia.

Conclusion

A sucker truck is one of the most practical tools a commercial or industrial site can call on, whether the job is a routine pit clean, a clogged wash bay or an urgent flood. The best results come from telling your provider exactly what needs removing, confirming how it will be handled and disposed of, and booking before a small build-up becomes a big problem.

We use our vacuum truck fleet to safely collect and transport hazardous industrial waste across Perth, from mine sites and workshops to commercial and civil projects, without anyone having to handle it directly. 

Here is what counts as industrial hazardous waste, why it needs specialist handling, and how we remove it safely and compliantly.

What Counts as Industrial Hazardous Waste?

Hazardous waste on a work site is rarely one single thing. It usually falls into a handful of categories, each with its own handling requirements.

Contaminated liquids are one of the most common, including hydrocarbon-laden wash water from car wash bays and mud pits, oily water from workshops, and chemical residues from industrial processes. 

Spent abrasive blasting media, commonly garnet, is another, since it picks up heavy metals, paint residue and coatings from whatever surface was being blasted, which changes how it needs to be handled and disposed of. Contaminated soil and spoil generated during vacuum excavation on a site with a known or suspected contamination history also needs careful management rather than being treated as general fill.

The Western Australian Government maintains a controlled waste category list that sets out which waste types require this kind of specialist handling and tracking, and it is worth checking against if you are unsure what you are generating on site.

Why Hazardous Waste Cannot Be Treated as General Waste

Hazardous waste is regulated the way it is because the risk does not disappear just because the waste is out of sight.

Tipping contaminated liquid into a drain, gully or general waste bin risks it entering the sewer or stormwater system, where it can contaminate waterways or damage infrastructure never designed to handle it. Under the Environmental Protection Act 1986, discharging waste in a way that causes pollution is an offence in Western Australia, and the consequences fall on whoever generated and released it, not just whoever moved it.

There is a practical risk too. Mixing incompatible wastes, or storing them without proper containment, can create reactions, fumes or spills that put workers and the surrounding site at risk. Specialist removal exists to take that risk out of the equation.

How We Remove Hazardous Waste Safely

Every job starts with identifying exactly what is being removed, because the waste type determines the equipment, the containment and where it can legally go.

We Assess the Waste Stream

Before any collection starts, we confirm what we are dealing with, whether that is contaminated wash water, spent blasting media, oily sludge or contaminated spoil. This determines the right vacuum equipment, containment and eventual disposal pathway.

We Collect It With Vacuum Recovery

Vacuum excavation and vacuum recovery are well suited to hazardous waste because the material is drawn directly into a sealed tank rather than being shovelled, poured or otherwise handled by hand. 

This keeps contact with the waste to a minimum and stops it spreading further across the site during collection. It applies equally to liquid waste from a wash bay or mud pit, garnet waste from a blasting enclosure, and contaminated spoil exposed during non-destructive digging.

We Contain and Transport It Compliantly

Once collected, hazardous waste is contained in the vacuum truck’s sealed tank for transport, keeping it separated from other waste streams and away from drains, stormwater and soil. We transport it to a facility licensed to accept that particular waste type, since different hazardous waste categories need to go to different licensed disposal or treatment points.

We Leave a Clear Record

Because hazardous waste movements need to be tracked, we keep clear records of what was collected, in what quantity, and where it went. That record matters if a site is ever audited, and it is good practice regardless.

Where Industrial Hazardous Waste Comes From

Hazardous waste turns up across a wide range of industrial and commercial activity in Perth, and each source needs a slightly different approach.

Why This Matters on Mining and Industrial Sites

Mining, industrial and civil sites tend to generate hazardous waste in larger volumes and on tighter schedules than a typical commercial property, which makes reliable removal even more important.

A blasting or maintenance program that cannot get spent media or contaminated liquid removed quickly risks stalling site operations. A wash bay that is not cleared regularly starts backing up, which affects everything that relies on it. We work with the mining, industrial, civil and commercial sectors across Western Australia, and we size the response to the volume involved, whether that is a single wash bay pit or a larger program of scheduled collections across a site.

Why Choose iVac WA

Handling hazardous waste properly takes the right equipment and a careful approach. Here is what we bring to every job:

• We operate the largest and most advanced vacuum truck fleet in Western Australia, giving us the capacity for both routine collections and larger volumes.
• We collect contaminated liquids, spent garnet media and contaminated spoil using vacuum recovery, minimising direct handling and the risk of spreading contamination further.
• We transport hazardous waste to facilities licensed to accept it, keeping different waste streams properly separated.

• We support Western Australia’s mining, industrial, civil and commercial sectors, with a focus on safe work and a fast turnaround.

Frequently Asked Questions

What is classed as industrial hazardous waste?

It covers a range of materials, including contaminated wash water, oily sludge, spent abrasive blasting media such as garnet, and contaminated soil or spoil. Western Australia’s controlled waste category list sets out the specific waste types that require specialist handling and tracking.

Can hazardous liquid waste go down a normal drain?

No. Hazardous liquid waste should never be discharged into a sewer, stormwater drain or gully. Doing so risks contaminating the wastewater or drainage network and is an offence under the Environmental Protection Act 1986 if it causes pollution.

How is garnet blasting waste removed?

Spent garnet picks up paint, coating and metal residue from whatever was being blasted, which changes how it needs to be handled. We use wet or dry vacuum collection to remove it from the blasting enclosure and transport it for appropriate disposal.

Do you treat or dispose of the hazardous waste yourselves?

We collect and transport hazardous waste using our vacuum truck fleet and deliver it to facilities licensed to accept that particular waste type. Treatment and final disposal are carried out at the licensed facility itself.

Is vacuum removal safer than manual handling?

Yes. Drawing waste directly into a sealed tank keeps contact with the material to a minimum and reduces the risk of spills or exposure compared with shovelling or manually decanting it, which is why vacuum recovery is the preferred method for hazardous waste on most sites.

Do you service mine sites as well as commercial properties?

Yes. We work across the mining, industrial, civil and commercial sectors in Western Australia, and we scale our response from a single wash bay collection to larger, scheduled programs on bigger sites.

Conclusion

Hazardous waste on an industrial or commercial site, whether it is contaminated wash water, spent blasting media or contaminated spoil, needs specialist collection, containment and transport, not a general waste bin or a drain. Vacuum recovery keeps the material contained from the point of collection through to a licensed facility, with a clear record of what was removed and where it went.

If your site is generating hazardous waste and you need it removed safely and compliantly, the right first step is a call to arrange collection before it becomes a bigger problem.

Liquid animal waste disposal in Perth is a regulated activity, and getting it wrong risks fines, pollution and damage to the property itself.

This guide explains what liquid animal waste is, why it needs careful handling, the rules that apply in Western Australia, and how it is safely and compliantly removed.

What Is Liquid Animal Waste?

Liquid animal waste covers any effluent, slurry or wastewater generated by keeping or handling animals. It includes manure and urine mixed with wash-down water, effluent from washing yards, pens and holding areas, run-off and pit waste from feedlots, poultry sheds and dairies, and wastewater from kennels, catteries, veterinary clinics and animal transport depots.

Unlike solid manure, which can often be composted or spread on land under the right conditions, liquid animal waste behaves like other wastewater. It carries a heavy organic and nutrient load, and if it is not captured and disposed of properly it can pollute soil, groundwater and waterways.

Why Liquid Animal Waste Cannot Just Be Hosed Away

It is tempting to simply hose down a pen or a wash bay and let the water run off. In Perth, that is exactly what should not happen.

Liquid animal waste carries high levels of nutrients, organic matter and often pathogens. Left to run into a stormwater drain, it flows untreated into local waterways and wetlands, and allowed onto the ground in the wrong place it can contaminate soil and groundwater. 

Because of this, liquid animal waste is treated as a form of trade waste or contaminated wastewater, not something that can be discharged without approval.

How Liquid Animal Waste Is Regulated in Western Australia

Understanding the rules explains why liquid animal waste disposal has to be handled carefully.

Larger animal-keeping operations, such as intensive piggeries, are regulated by the Department of Water and Environmental Regulation under the Environmental Protection Act 1986. Depending on their scale, these operations need a works approval, registration or a licence, and their effluent must be contained, typically in drains and ponds, to protect surface water and groundwater.

If liquid animal waste is to be discharged to the sewer, it counts as trade waste, and Western Australian law requires prior approval. The Water Corporation issues trade waste permits for businesses wanting to discharge non-domestic wastewater to its sewers, assessing each application to make sure the waste is compatible with the system and does not put the network, its workers or the treatment process at risk. 

Where liquid animal waste cannot go to the sewer, it has to be collected and taken to an appropriate disposal or treatment facility instead. In short, from a small kennel to a large feedlot, liquid animal waste always has to go somewhere approved, never simply onto the ground or into a drain.

How Liquid Animal Waste Is Safely Removed

Removing liquid animal waste properly comes down to containing it and getting it to the right place, without any spillage along the way.

The waste is first assessed, so the volume and the appropriate disposal route, whether that is a licensed facility or a sewer connection under a trade waste permit, can be confirmed. It is then captured directly from pits, ponds, sumps, wash bays and holding pens using vacuum equipment, which draws the waste into a sealed tank rather than pumping or hosing it across the ground. 

This matters because vacuum extraction keeps the waste fully contained from the moment it leaves the pit to the moment it reaches its destination, avoiding any spillage or seepage into surrounding soil.

Vacuum equipment is particularly well suited to this kind of waste. It can handle thick manure slurry as easily as diluted wash-down water, drawing both into the same sealed tank without the operator needing to touch or wade into the material. 

For a property with several pits, pens or wash bays, a vacuum truck can also work through them in sequence in a single visit, rather than requiring separate handling for each source.

Once collected, the waste is transported to an approved disposal point, whether that is a treatment facility or, where a trade waste permit is in place, the sewer system under the agreed conditions. Regular removal also matters for the property itself. 

Left too long, pits and ponds overflow, wash bays back up, and odour and pest problems follow, so scheduled collection keeps a facility compliant and functioning.

Sources of Liquid Animal Waste and How They Are Handled

Different facilities generate different waste, and the right removal approach depends on the source.

The Cost of Getting It Wrong

Ignoring liquid animal waste, or trying to manage it with a hose and a drain, tends to cost more in the long run than handling it properly from the start.

Pollution is the biggest risk. Because liquid animal waste is high in nutrients and organic matter, an uncontrolled discharge into a drain or onto the ground can contaminate soil, groundwater and nearby waterways, and in Western Australia that is a breach of environmental law. 

For regulated operations such as intensive piggeries, mismanaging effluent can also put a works approval, registration or licence at risk. Beyond the regulatory side, there is a practical cost too, an overflowing pit or pond means a mess to clean up, odour that affects staff, customers or neighbours, and pests attracted to standing waste. 

Scheduled, compliant collection avoids all of this, and it is almost always cheaper than dealing with an overflow, a fine or a damaged approval after the fact.

Why Choose iVac WA

Liquid animal waste needs to be captured cleanly and taken to the right place, and that is exactly what we deliver. Here is what we bring to every job:

• We are Perth’s leading vacuum excavation and liquid waste specialists, operating the largest and most advanced vacuum truck fleet in Western Australia.
• We safely collect liquid animal waste, effluent and wash-down water from pits, ponds, sumps and holding pens, and transport it for approved disposal.
• We extract waste cleanly with no spillage, protecting the surrounding soil, drains and waterways.
• We provide car wash bay and mud pit cleaning, along with stormwater cleaning and emergency flood response, for rural and agricultural sites.
• We support Western Australia’s agricultural, mining, industrial and commercial sectors, with a focus on safe work and a fast turnaround.

Because we run a large, dedicated vacuum fleet, we can handle regular scheduled collections or one-off clean-outs, whatever a property needs.

Frequently Asked Questions

Can liquid animal waste be hosed into a drain?

No. Liquid animal waste carries a heavy organic and nutrient load, and stormwater drains flow untreated into waterways, so hosing it away is both a pollution risk and against the rules. It must be captured and disposed of at an approved facility, or discharged to sewer only under an approved trade waste permit.

Do I need approval to discharge liquid animal waste to the sewer?

Yes. Any business wanting to discharge trade waste, including liquid animal waste, to the Water Corporation’s sewer system needs a trade waste permit, and the application is assessed to confirm the waste is compatible with the network before approval is given.

How is liquid animal waste collected?

It is captured with vacuum equipment directly from pits, ponds, sumps, wash bays and holding pens, drawing it into a sealed tank rather than pumping or hosing it across the ground. This keeps the waste fully contained during collection.

How often should liquid animal waste be removed?

It depends on the volume a property generates. Busy farms, feedlots and saleyards often need a regular collection schedule to prevent pits and ponds overflowing, while smaller operations such as kennels or vet clinics may only need occasional collection. We can help set a schedule that suits your site.

What happens if liquid animal waste is not managed properly?

Overflowing pits and ponds, odour and pest problems, and pollution of soil, groundwater or waterways can all follow. For regulated operations, non-compliance can also mean breaching licence or approval conditions.

Do you service rural and agricultural properties across WA?

Yes. We provide liquid waste collection and vacuum services across Perth and wider Western Australia, including rural and agricultural sites.

Conclusion

Liquid animal waste is a fact of life on any property that keeps or handles animals, but it is not something that can be left to run off or hosed away. Containing it properly, whether in pits, ponds or bunded areas, and having it collected and disposed of through an approved route protects the environment, keeps a facility compliant, and prevents the overflow and odour problems that come with leaving it too long.

Whether it is a farm, a feedlot, a saleyard or a veterinary clinic, regular, properly managed removal is the simplest way to stay on top of it.

For any site dealing with PFAS-contaminated water, soil or sludge, safe removal and disposal is a regulated, specialist job.

This guide explains what PFAS is, where PFAS waste comes from, why it cannot simply be tipped away, and how it is safely removed, transported and disposed of in Perth and wider Western Australia.

What Is PFAS and Why Is It a Problem?

PFAS stands for per- and polyfluoroalkyl substances, a large family of synthetic chemicals valued for their resistance to heat, water and stains. They have been used for decades in products such as firefighting foam, non-stick coatings, waterproofing and stain protection.

The same durability that made PFAS useful is exactly what makes it a problem. They are so resistant to breaking down that they are often called forever chemicals, and once they enter the environment they persist for a very long time, moving through groundwater and accumulating over time. 

Because of the risks this poses to health and the environment, PFAS is now tightly regulated, which is why its waste has to be handled with far more care than ordinary material.

Where PFAS Waste Comes From

PFAS turns up in a range of settings, and the waste is often generated during clean-up, maintenance or investigation works.

The best-known source is aqueous film-forming foam, or AFFF, the firefighting foam once widely used at airports, defence sites and fire training grounds. Beyond that, PFAS is commonly detected near landfills, wastewater treatment plants and other waste facilities, as well as at industrial sites where PFAS-containing products were used. 

Contaminated water can collect in bunds, sumps, pits and ponds, while contaminated soil and sediment are often generated during site investigation and remediation. In each case, that material becomes a waste stream that has to be captured and disposed of properly.

Why PFAS Waste Cannot Just Be Tipped Away

Ordinary waste can go to an appropriate landfill or down a licensed drain. PFAS waste cannot, and treating it like general waste is both illegal and environmentally damaging.

Because PFAS is so persistent and mobile, allowing contaminated water or soil to enter the ground, a drain or an unlicensed landfill risks spreading the contamination further. 

That is why PFAS waste is captured, contained and directed only to facilities licensed to accept it. In Western Australia, contaminated liquid waste is classed as controlled waste, which brings strict rules around how it is transported and where it can go.

How PFAS Waste Is Regulated in Western Australia

Safe PFAS disposal sits within a clear regulatory framework, and understanding it explains why the process is so careful.

At the national level, the PFAS National Environmental Management Plan, known as the PFAS NEMP, provides the how-to guide for investigating and managing PFAS contamination and waste. Its latest edition, version 3.0, was published in March 2025 and has been adopted in Western Australia, where the Department of Water and Environmental Regulation regulates PFAS-contaminated sites.

At the state level, PFAS-contaminated liquid is a controlled waste. The transport of controlled waste on WA roads is regulated by DWER under the Environmental Protection (Controlled Waste) Regulations 2004, which require carriers, drivers and vehicles to be licensed, and movements to be tracked. 

Solid PFAS waste, such as contaminated soil and sediment, can only go to landfills licensed to accept it, within set concentration limits, and it must not be diluted to meet those limits. In short, from the moment it is collected to the moment it is disposed of, PFAS waste is closely controlled.

How PFAS Waste Is Safely Removed and Disposed Of

Removing PFAS waste properly follows a careful sequence, and each step is designed to keep the contamination contained.

It starts with assessment, classifying the waste so it can be directed to the right licensed facility. Contaminated water, sludge and soil are then safely collected and contained. This is where vacuum equipment is invaluable, extracting contaminated water and slurry from bunds, sumps and pits cleanly, with no spillage and no cross-contamination of clean ground. 

The waste is then transported by a licensed carrier to a licensed facility, with the movement tracked as required.

The collection stage matters more than it might seem. Because PFAS spreads so easily, the goal at every step is to keep the contaminated material fully contained, drawing it directly into a sealed tank rather than letting it splash, leak or soak into surrounding soil. 

A vacuum truck is well suited to this, handling water, slurry and sludge together and keeping the whole load enclosed from the point of collection through to the licensed facility. Doing this cleanly is what separates a compliant PFAS removal from one that simply moves the problem around.

At the facility, the material is treated or disposed of according to its type. Contaminated water is typically treated with technologies such as granular activated carbon or ion exchange, which separate the PFAS from the water. Contaminated soil and sediment are disposed of at a licensed landfill, or treated through methods such as stabilisation. The common thread is that the PFAS is contained and managed, never simply released.

PFAS Waste Types and How They Are Handled

Different PFAS waste streams call for different handling, and the first step is always to identify what you are dealing with.

Why Getting Disposal Right Matters

With PFAS, the stakes for doing it properly are high. Because the contamination is persistent and mobile, a spill or an improper disposal does not simply go away, it can spread through soil and groundwater and become a long-term problem that is difficult and expensive to remediate.

There is a compliance dimension too. PFAS waste sits within a strict regulatory framework, and mishandling it, whether by disposing of it as ordinary waste, allowing it to enter a drain, or transporting it without the right controls, can carry serious consequences. 

For a business or site operator, that makes the choice of how contaminated material is captured and moved just as important as where it eventually goes. Using the right equipment and a careful, contained process protects the environment, the site and the operator all at once.

Frequently Asked Questions

What is PFAS and why is it dangerous?

PFAS is a family of synthetic chemicals known as forever chemicals because they resist breaking down. They persist in the environment, move easily through soil and water, and accumulate over time, which is why they are now tightly regulated and their waste must be handled carefully.

Can PFAS waste go to normal landfill?

No. PFAS-contaminated soil can only go to a landfill specifically licensed to accept it, within set concentration limits, and contaminated liquid is a controlled waste that must go to a licensed facility. Disposing of PFAS waste as ordinary waste is illegal and spreads the contamination.

How is PFAS-contaminated water removed?

It is captured and contained, often with vacuum equipment that extracts it cleanly from bunds, sumps and pits, then transported by a licensed carrier to a facility where it is treated to separate the PFAS from the water.

Is transporting PFAS waste regulated in WA?

Yes. Contaminated liquid is a controlled waste, and its transport on WA roads is regulated by the Department of Water and Environmental Regulation, requiring licensed carriers and vehicles and tracked movements.

Do you dispose of the PFAS yourselves?

We handle the safe collection, containment and transport of PFAS-contaminated water and waste, and deliver it to licensed facilities where the treatment and disposal takes place. Our role is to capture and move the material cleanly and compliantly.

What sites typically need PFAS waste removal

Common ones include former firefighting training grounds, airports and defence sites, industrial facilities, and any contaminated site undergoing investigation or remediation where contaminated water, soil or sludge is generated.

Conclusion

PFAS is not a contaminant to take shortcuts with. It is persistent, mobile and closely regulated, and disposing of it as ordinary waste risks both a serious environmental problem and a breach of the rules. Safe PFAS waste removal means capturing and containing the material cleanly, transporting it as a controlled waste, and disposing of it only at licensed facilities.

Whether it is contaminated water in a bund, slurry in a sump, or soil from a remediation project, the right equipment and a careful process keep the contamination contained from start to finish.

The trouble is that a stormwater blockage usually builds up out of sight, so the first sign is often water pooling where it should not. Understanding what causes these blockages, spotting them early, and knowing how they are properly cleared can save a site a great deal of damage and downtime.

Here is a practical guide to blocked stormwater drains in Perth, the common causes, the warning signs, and the fixes that actually work.

How Stormwater Drains Work

Stormwater drains are entirely separate from the sewer system. Rather than carrying wastewater to treatment, they collect rainwater from surfaces and direct it, untreated, into soakwells, drainage networks and ultimately local waterways. The Water Corporation, which manages much of the metropolitan drainage network, designs these systems to move large volumes of water quickly during rain.

Because the water is not treated, only rainwater should ever enter a stormwater drain. That is why keeping them clear, and keeping pollutants out, matters for both drainage and the environment.

Common Causes of Blocked Stormwater Drains in Perth

Several things clog stormwater systems, and in Perth some are more common than others.

The biggest culprit is sand and silt. Perth sits on the sandy soils of the Swan Coastal Plain, and the Department of Primary Industries and Regional Development notes that the region’s pale sandy soils are loose and free-draining, so fine sand washes into stormwater pits and pipes with every rain and settles at the bottom. Over time it builds into a layer that chokes the flow.

Leaf litter and organic debris are another major cause, blocking grates and filling pits, especially where there is landscaping or established trees nearby. Sediment and soil from construction, earthworks and landscaping runoff wash in and settle just like sand. Litter and rubbish collect at grates and inlets. 

Tree roots chase moisture into stormwater pipes and grow until they choke the line. And on commercial and industrial sites, sediment from car parks, wash bays and hardstands adds to the load.

Underlying all of this, a stormwater system can also block because a pipe has cracked, collapsed or sagged, or because a soakwell has filled with sediment and stopped draining. 

These are the problems that keep coming back until they are properly diagnosed and fixed.

Signs of a Blocked Stormwater Drain

A blocked stormwater drain usually gives clear warning before it causes serious flooding. Watch for these signs on a site:

• Water pooling or ponding on surfaces that should drain freely
• Drains and pits that are slow to clear after rain
• Water overflowing from stormwater pits or gullies
• Localised flooding in car parks, yards or low-lying areas
• Gurgling sounds or a bad smell around the drains
• Erosion or damp patches near where water is escaping

Any of these means the system is not coping, and it is far better to act before the next heavy rain than to deal with a flood.

Why It Matters in Perth

Perth’s climate makes stormwater maintenance particularly important. Much of the year’s rain falls in intense winter downpours, so a system that is even partly blocked can be quickly overwhelmed. 

The Department of Water and Environmental Regulation’s Stormwater management manual for Western Australia sets out the state’s approach to managing stormwater quantity, quality and flooding, and keeping systems clear and functioning is central to it. Many properties also rely on soakwells to dispose of stormwater on site, and when those soakwells fill with sand and sediment, they stop working and water backs up across the surface.

There is an environmental dimension too. Because stormwater flows untreated into waterways, allowing pollutants, sediment or contaminated water into the system is a problem, and in Western Australia it is an offence, as the state’s Environment Watch guidance makes clear. 

Keeping stormwater drains clear, and capturing any waste rather than flushing it downstream, protects both the site and the environment.

How to Fix a Blocked Stormwater Drain

The right fix depends on the cause, which is why the first step is always to find out what is actually going on.

For a minor surface blockage, clearing leaf litter and debris from the grate can restore flow. But when the blockage is further down, in the pits, pipes or soakwells, it needs professional equipment to clear it properly.

The most effective solution is jet/vac cleaning. High-pressure water jetting breaks up the silt, sand, roots and debris inside the pipe or pit, while a powerful vacuum draws the loosened material and water out of the system entirely. 

This restores the drain to full capacity rather than just clearing a narrow channel, and because the waste is captured in the truck rather than flushed downstream, it does not simply cause the next blockage.

For soakwells, the fix is vacuum cleaning to remove the accumulated sand and sediment and restore their capacity. Where a blockage keeps returning, a CCTV inspection identifies the underlying cause, such as a collapsed pipe or root intrusion, so it can be repaired rather than repeatedly cleared. 

And when heavy rain has already caused flooding, emergency flood response pumps and vacuums the water away to protect the site.

The best fix of all is prevention. Clearing stormwater drains and soakwells once a year, ideally before winter, keeps a system ready for the rain and avoids the cost and disruption of a flood.

Frequently Asked Questions

What causes stormwater drains to block in Perth?

The most common causes are sand and silt washing in from Perth’s sandy soils, along with leaf litter, sediment from construction and landscaping, litter, and tree roots. A stormwater drain can also block because a pipe has collapsed or a soakwell has filled with sediment and stopped draining.

How do I know if my stormwater drain is blocked?

The clearest sign is water pooling on surfaces that should drain freely, or pits that are slow to clear after rain. Overflowing pits, localised flooding, gurgling and bad smells are all signs the system is not coping.

Can a blocked stormwater drain be cleared without digging?

Yes. Jet/vac cleaning clears the blockage from inside the pipe or pit using high-pressure water and vacuum recovery, with no excavation needed. If a camera inspection reveals a collapsed pipe, a targeted repair may be required, but the cleaning itself is non-destructive.

Should soakwells be cleaned too?

Yes. Soakwells fill with sand and sediment over time, which stops them draining and causes water to back up across the surface. Vacuum cleaning removes the sediment and restores their capacity, ideally once a year before winter.

How often should stormwater drains be cleaned?

Once a year is a sensible guide for most sites, ideally before the winter rain arrives. Sites with heavy leaf fall, sandy surrounds or a history of blockages may benefit from more frequent cleaning.

Do you provide emergency flood response in Perth?

Yes. We provide fast call-outs across Perth and wider Western Australia, including emergency flood response to pump and vacuum water away when heavy rain overwhelms a site.

Conclusion

A blocked stormwater drain is one of those problems that stays hidden until the rain arrives, and then it becomes urgent all at once. In Perth, where winter downpours are intense and many sites rely on soakwells, keeping stormwater systems clear is essential to avoiding flooding and damage. 

Sand, silt, leaves and roots are the usual causes, and jet/vac cleaning is the fix that clears them properly and keeps the waste out of the environment.

Watch for pooling water and slow-clearing pits, deal with blockages early, and clear your stormwater drains and soakwells before winter rather than after the flood.

The good news is that most of that risk is avoidable. Regular jet cleaning keeps drains clear before a blockage ever forms. 

So how often should the drains at a Perth commercial, industrial or civil property actually be jet cleaned? There is no single answer that suits every site, because it depends on the type of property, the age of the pipes, and what goes down the drains. But there are clear guidelines, and this article walks through them, along with the signs that tell you not to wait.

What Is Drain Jet Cleaning?

Drain jetting, also called hydro jetting, uses a high-pressure stream of water to clean the inside of a pipe. A hose with a specialised nozzle is fed into the drain, and water is delivered at high pressure to cut through grease, slice out tree roots, and flush away the silt, sand and debris that build up over time. 

Unlike a plunger or a chemical cleaner, which only deal with the immediate clog, jetting scours the whole pipe back to its full diameter, so the flow is properly restored.

Used as planned maintenance rather than an emergency fix, it is one of the simplest ways to keep a site’s drainage reliable.

How Often Should Commercial Drains Be Jet Cleaned?

As a general guide, most commercial premises benefit from a preventative jet clean at least once a year, while high-demand sites such as food premises need it far more often. The right interval depends on how quickly a particular property builds up grease, sediment or waste. 

The table below sets out a sensible starting point for different property types.

These are starting points, not fixed rules. The best way to set the right schedule for a site is to have the drains inspected with a camera, with any defects graded to the national WSA 05 Conduit Inspection Reporting Code. This shows their real condition and how quickly they tend to build up.

What Affects How Often You Need It?

Several factors push a property towards the more frequent end of the scale.

The first is what goes down the drains. Fats, oils and grease from commercial kitchens are a leading cause of blockages, hardening inside the pipe and trapping everything that follows. Wash bays, workshops and industrial processes send sand, sludge and sediment into the lines. 

The Water Corporation, which runs much of the metropolitan network, urges customers to keep grease and non-flushable items such as wet wipes out of the drain, since neither breaks down the way it should and both are common culprits in wastewater blockages.

The age and material of the pipes matter too. Many older commercial and industrial sites still have clay or earthenware drainage, which is more prone to cracking, root intrusion and rough internal surfaces that catch debris. Trees are another factor. 

Perth’s sandy soils drain quickly, so tree roots seek out the moisture inside pipes and force their way in through the smallest crack or joint, which is a common problem on established sites with landscaping. 

Finally, usage intensity counts. A busy restaurant, a high-traffic car park or a round-the-clock industrial site will all build up faster and need more frequent cleaning than a quiet office.

Signs You Should Not Wait for the Schedule

Regular jetting is about prevention, but the drains will also tell you when they need attention sooner. Book a clean if you notice any of these on site:

• Water draining slowly across several fixtures, not just one
• Gurgling sounds from drains, floor wastes or toilets
• A persistent bad or sewage-like smell affecting staff or customers
• Drains that block again soon after being cleared
• Wastewater backing up through a floor drain or gully when another fixture is used

Any of these suggests buildup is already narrowing the pipe, and dealing with it early is far cheaper and less disruptive than a full blockage during trading hours.

The Benefits of Sticking to a Schedule

Treating jetting as routine maintenance rather than an emergency call-out pays off across a business.

It prevents blockages before they happen, which avoids the downtime, closures and clean-up costs of a backed-up drain. It supports compliance, which matters for food premises and any site with health, safety or environmental obligations.

It protects the pipes, since removing grease, roots and sediment reduces the strain that leads to cracks and collapses. It saves money over time, because a planned clean is far cheaper than an emergency call-out and the damage an overflow can cause. 

And for stormwater drains and soakwells, an annual clean before winter helps a site cope with heavy rain rather than flooding.

Frequently Asked Questions

How often should commercial drains be jet cleaned in Perth?

As a general guide, at least once a year for most commercial premises, and every three months for food premises where grease builds up quickly. Industrial sites, car parks and wash bays often need cleaning every 6 to 12 months, and stormwater drains and soakwells are best cleared once a year before winter.

Does jetting damage pipes?

For sound pipes, no, when the pressure is matched to the pipe by a trained operator. We inspect the line with a camera first to confirm it is structurally sound before jetting, which also identifies any pipe that needs assessment rather than cleaning.

Is regular jetting really necessary if the drains seem fine?

Preventative jetting stops blockages before they start, which is cheaper and far less disruptive than an emergency during trading hours. Buildup happens gradually and silently, so a drain can look fine right up until it blocks. Regular cleaning keeps a site ahead of it.

How do I know if a site’s drains need cleaning sooner?

Watch for slow drainage across several fixtures, gurgling, bad smells, or blockages that keep returning. Any of these means buildup is already narrowing the pipe, and it is worth booking a clean before it becomes a full blockage.

Should stormwater drains and soakwells be jetted too?

Yes. Soakwells and stormwater drains fill with sand, silt and leaf litter over time, which reduces their capacity. Clearing them once a year, ideally before winter, helps a site handle Perth’s heavy rain and reduces the risk of flooding.

Do you offer emergency drain cleaning in Perth?

Yes. We provide fast call-outs across Perth and wider Western Australia, including emergency flood response and urgent blockages that cannot wait.

Conclusion

The simplest way to avoid a blocked drain is to clean the pipe before it ever gets the chance to block. For most Perth commercial sites, an annual jet clean does the job, with quarterly cleaning for food premises, more frequent attention for industrial sites, car parks and wash bays, and a yearly clear of stormwater drains and soakwells before winter. 

Watch for the warning signs, and do not wait for the schedule if the drains are already struggling.

A little planned maintenance keeps a site’s drainage flowing, protects the pipes, and saves you from the downtime and cost of an emergency.

Strike one with an excavator bucket and the consequences can be severe, from a dangerous gas leak or electrocution to a costly service outage and a stalled project.

Vacuum digging removes that risk. Instead of cutting into the ground with a mechanical blade, it loosens the soil gently and draws it away with powerful suction, so buried services can be uncovered without being touched. 

It is faster, cleaner and, above all, far safer than traditional digging. Here is what vacuum digging is, how it works, and why it has become the smart way to dig in Perth.

What Is Vacuum Digging?

Vacuum digging, also known as vacuum excavation or non-destructive digging (NDD), is a method of removing soil without a digging blade. 

A truck-mounted system uses either pressurised water or compressed air to break up the ground, and a high-powered vacuum then draws the loosened material up through a hose and into a debris tank on the truck.

The two methods suit different jobs. Hydro excavation uses a jet of water to cut the soil into a slurry, which works well in most of Perth’s soil types. Air excavation uses compressed air, which keeps the spoil dry so it can often be reused as backfill. 

In both cases, the key point is the same, the soil is removed by suction rather than by force, which is what makes the method so safe and precise.

How Vacuum Digging Works

The process is straightforward. The operator directs a lance into the dig site, using water or air to loosen the soil. As the ground breaks up, the vacuum hose draws the spoil away and stores it in the debris tank. 

The operator works steadily, exposing whatever lies below, whether that is a buried cable, a pipe, or simply the bottom of a planned excavation. 

Because the operator has full control over where the water or air is directed, the dig is precise and the surrounding ground stays largely undisturbed.

Why Vacuum Digging Is Safer

Safety is the reason vacuum digging has replaced mechanical excavation on so many jobs. It is safer on several fronts at once.

It Protects Underground Services

This is the biggest benefit. A mechanical excavator cannot see what it is digging into, so it can slice through a gas main or a power cable without warning. 

Vacuum digging loosens the soil gently and draws it away, so an operator can expose a live service and leave it completely intact. That prevents the gas leaks, electrocution risks, outages and expensive repairs that come with a strike.

It Keeps Workers Safer

Traditional excavation often puts people close to heavy machinery, open trenches and unseen hazards. Vacuum digging reduces that exposure. There is no swinging bucket near buried power, and far less need for workers to dig by hand around dangerous services. The operator controls the dig from a safe position, which lowers the risk of injury.

It Is Precise and Controlled

Because the soil is removed a little at a time under the operator’s control, vacuum digging produces neat, accurate holes exactly where they are needed. That precision matters when exposing a service in a congested corridor, or digging close to structures where a mechanical excavator would be too blunt an instrument.

It Causes Less Damage

With a small, targeted dig rather than a wide trench, vacuum digging leaves far less surface to reinstate. Driveways, paving, landscaping and roads are disturbed as little as possible, which saves time and money on making good afterwards.

Why It Matters in Perth

Vacuum digging is especially well suited to conditions here in Perth and wider Western Australia.

The metropolitan area is growing quickly, and its underground service corridors are increasingly congested with power, gas, water, sewer and telecommunications assets, often running close together. That density makes safe, precise digging essential. 

Perth’s sandy soils also lend themselves to hydro excavation, which cuts through them cleanly and efficiently.

Just as important, safe digging is backed by clear rules. Before any excavation, a free enquiry should be lodged with Before You Dig Australia, which provides plans showing where registered underground services are located.

Those plans are a guide, not a precise map, so the services still need to be physically exposed. Western Power sets out this approach for work near its network, describing non-destructive digging as breaking up the ground with high-pressure air or water and removing it with a powerful vacuum, and listing potholing as a core step in digging safely. Vacuum digging is how that best practice is put into action on site.

Vacuum Digging vs Traditional Excavation

The difference between the two methods is clearest when you set them side by side.

What Vacuum Digging Is Used For

The safety and precision of vacuum digging make it useful across a wide range of jobs. It is used to locate and expose underground services before construction, a process called potholing or daylighting. 

It digs holes for posts, poles, pits and footings without endangering nearby assets, and opens trenches for cables and conduit. It supports directional drilling by exposing crossing services along the bore path, and it works in tight or sensitive spots where a mechanical excavator cannot safely operate. 

From civil and telecommunications projects to mining, industrial and commercial sites, it is the method of choice wherever there is something valuable in the ground.

Why Choose iVac WA

Frequently Asked Questions

What is the difference between vacuum digging and normal excavation?

Vacuum digging removes soil with water or air and powerful suction, rather than with a mechanical digging blade. This lets it expose buried services without cutting or crushing them, which is why it is so much safer than a conventional excavator around underground assets.

Is vacuum digging safe around gas and power?

Yes, that is its main purpose. Because the soil is loosened gently and drawn away by suction, an operator can expose a live gas main or power cable and leave it completely intact. It is the method utilities and regulators recommend for working near underground services.

What is the difference between hydro and air vacuum digging?

Hydro digging uses pressurised water to cut the soil, while air digging uses compressed air and keeps the spoil dry so it can be reused as backfill. Water suits most of Perth’s soils, and air is chosen where dry, reusable spoil is an advantage.

Do I still need Before You Dig plans if I use vacuum digging?

Yes. A Before You Dig Australia enquiry provides plans showing where registered services are located, and vacuum digging then confirms their exact position on site. The two work together, plans tell you roughly where to look, and vacuum digging exposes the services safely.

Is vacuum digging only for large projects?

No. While it is essential on major civil, mining and telecommunications projects, it is just as useful for smaller jobs, such as exposing a service before a build, digging post holes near cables, or clearing around existing pipework.

Do you offer vacuum digging across Perth?

Yes. We provide vacuum digging and non-destructive excavation across Perth and wider Western Australia, with a large fleet and a fast turnaround.

Conclusion

Digging near underground services is one of the riskiest parts of any project, and a single strike can be dangerous and costly. Vacuum digging takes that risk out of the equation, removing soil with suction rather than force so that services are exposed intact, workers stay safer, and the surrounding ground is barely disturbed. 

In a growing, service-dense city like Perth, that combination of safety and precision is exactly what modern excavation calls for.

Whether you are exposing utilities before construction, digging in a congested corridor, or working close to sensitive assets, vacuum digging is the safe, smart way to break ground.

That is exactly why vacuum excavation has become the standard method for digging on NBN and telecom projects across Western Australia. Instead of a blade cutting blindly through the ground, vacuum excavation removes soil with water or air and powerful suction, exposing cables and conduit precisely and without damaging them. For an industry where the assets are fragile, densely packed and business-critical, it is the only sensible way to dig.

Here is how vacuum excavation supports NBN and telecom work in WA, why it matters, and where it fits into a project from planning through to installation.

Why Telecom Projects Rely on Vacuum Excavation

The stakes on a telecom site are unusually high, and three factors make careful digging essential.

The first is how fragile the assets are. Fibre optic cables and their conduit are easily crushed, cut or stretched, and even minor contact can degrade a connection. The second is congestion. Telecom cables rarely run alone, they share tight underground corridors with power, gas, water and other comms, so exposing one service means working safely around several others. The third is the sheer cost of getting it wrong.

The scale of the network shows why. The nbn network is the largest infrastructure project in Australia’s history, and more than 12 million homes and businesses can now connect to it. According to Before You Dig Australia, more than 1,200 incidents of damage to nbn infrastructure were reported in 2023 alone, causing costly repairs and widespread service interruptions. Even a small cut can leave a whole region without the internet, disrupting businesses, schools, hospitals and households.

Vacuum excavation removes that risk. Because the soil is loosened gently and drawn away by suction rather than struck, an operator can uncover a live fibre cable or a bank of conduit and leave it completely intact.

What Is Vacuum Excavation?

Vacuum excavation, also called non-destructive digging or NDD, uses a truck-mounted system to break up and remove soil without a mechanical digging blade. There are two main methods. Hydro excavation uses a jet of pressurised water to cut the soil into a slurry, while air excavation uses compressed air to loosen it and keep the spoil dry so it can often be reused as backfill. In both cases, a high-powered vacuum then draws the loosened material up through a hose into a debris tank.

The advantage for telecom work is control and safety. The method exposes buried services precisely, without the impact, vibration or blind force of an excavator, which is why utilities and asset owners across the country ask for it when their assets are involved.

How Vacuum Excavation Is Used on NBN and Telecom Projects

Vacuum excavation is not limited to one task. It supports telecom work from the first site investigation right through to installation.

Locating and Exposing Existing Services

Before any new work begins, crews need to know exactly what is already in the ground. A Before You Dig Australia enquiry provides plans showing registered services, including nbn assets, but those plans are a guide, not a precise map. This is where potholing comes in. 

Vacuum excavation digs small, targeted holes to physically expose and confirm the exact position and depth of existing cables and conduit, a process often called daylighting. Lodging a free Before You Dig Australia request is the essential first step, and vacuum excavation is what turns those plans into verified, visible reality on site.

Exposing Fibre and Conduit Without Damage

When an existing comms line has to be worked around, joined or relocated, it must be uncovered without a scratch. Vacuum excavation is ideal for exposing green nbn fibre, copper cables and conduit banks intact, so cablers can carry out their work on assets that are undamaged and clearly visible.

Digging Pits, Pillars and Joint Bays

Telecom networks need pits, pillars, joint bays and hauling points at regular intervals. Vacuum excavation digs these neatly and to precise dimensions, even in congested areas where a mechanical digger could not safely operate, and with far less surface damage to reinstate afterwards.

Supporting Directional Drilling and Trenching

Much telecom conduit is installed by horizontal directional drilling, which bores a path underground beneath roads, driveways and landscaping. Before the drill runs, vacuum excavation potholes along the bore path expose any crossing services, so the drill head can be guided safely past them. It is also used to expose the entry and exit points of a bore, and to open the narrow trenches used for conduit and micro-trenching, without endangering nearby assets.

Cleaning and Clearing Conduit and Pits

Existing pits and conduit often fill with silt, sand and debris over time, which blocks cable hauling. Vacuum equipment clears them out quickly and cleanly, ready for new cable to be pulled through.

Vacuum Excavation vs Traditional Digging on Telecom Sites

On a telecom project, the difference between methods is not just convenience, it is risk.

Safety, Compliance and Duty of Care

Working near underground services in Western Australia carries clear legal and safety responsibilities, and vacuum excavation is central to meeting them.

The process starts with locating. A free Before You Dig Australia enquiry notifies asset owners, who supply plans of their infrastructure. From there, the recognised safe-digging steps apply: plan the job, pothole to expose services, protect the exposed assets, and only then proceed. 

Western Power sets out this approach for work near its network, describing non-destructive digging as breaking up the ground with high-pressure air or water and removing it with a powerful vacuum, and listing potholing as a core safe-excavation step. The same discipline protects telecom assets, which frequently share those corridors with power.

There is also a duty of care. Telecom asset owners such as nbn and Telstra require that only authorised people work on their infrastructure, and that excavators take reasonable steps to avoid damage. Vacuum excavation is how a responsible contractor demonstrates that care, exposing services without harming them and keeping a project compliant, safe and on schedule.

How Vacuum Excavation Saves Time and Money

Beyond safety, vacuum excavation makes commercial sense on telecom projects.

Avoiding a strike is the biggest saving of all. A damaged fibre line means emergency repairs, potential fines, a stalled project and, often, an unhappy client and community. Vacuum excavation removes that exposure. 

It is also precise, so there is far less surface to reinstate than with a wide open trench, and it works in tight, congested spots where a mechanical plant would be slow, risky or simply unable to fit. Air excavation adds further efficiency by keeping the spoil dry and reusable as backfill, cutting disposal costs.

For civil contractors, telecom carriers and network builders, that combination of safety and efficiency keeps projects moving and budgets under control.

Frequently Asked Questions

Why is vacuum excavation used instead of a digger on telecom projects?

Because fibre optic cables and conduit are fragile and easily damaged, and a strike can cause a major outage. Vacuum excavation removes soil with water or air and suction rather than a blade, so it exposes those assets precisely without cutting or crushing them.

Can vacuum excavation expose fibre optic cables without damaging them?

Yes. That is one of its main uses. The soil is loosened gently and drawn away by suction, so a cable or conduit can be uncovered and left completely intact, ready for cablers to work on.

Do I still need Before You Dig plans if I am using vacuum excavation?

Yes. A Before You Dig Australia enquiry provides plans showing where registered services, including nbn assets, are located. Vacuum excavation then physically confirms their exact position on site. The two work together, plans tell you roughly where to look, and potholing confirms it safely.

What is the difference between hydro and air excavation for telecom work?

Hydro excavation uses pressurised water to cut the soil, while air excavation uses compressed air and keeps the spoil dry so it can be reused as backfill. Both are non-destructive and safe around fibre and conduit, and the right choice depends on the site and soil conditions.

Does vacuum excavation help with directional drilling?

Yes. Before a horizontal directional drill runs, vacuum excavation potholes along the bore path expose crossing services, so the drill can be guided safely past them. It is also used to open bore entry and exit points.

Do you work with civil contractors and telecom carriers in WA?

Yes. We support civil contractors, telecommunications carriers and network builders across Perth and wider Western Australia, providing the vacuum excavation that keeps telecom projects safe and on schedule.

Conclusion

On an NBN or telecom project, the ground is full of fragile, business-critical infrastructure, and one careless dig can take a community offline. Vacuum excavation is the method built for exactly this challenge, exposing and installing cables and conduit with precision, protecting the network, and keeping projects safe, compliant and on time. From locating and potholing to pit excavation and directional drilling support, it is the smart way to dig where the margin for error is zero.

Whether you are building new telecom infrastructure, maintaining an existing network, or exposing services before construction, the right vacuum excavation partner makes all the difference.

But what exactly is a vacuum truck, how does it work, and why are there so many different types? Whether you are a property owner, a builder, a council engineer or simply curious, this guide explains everything in plain terms. We work with these trucks every day across Perth, so we will also show you where each type earns its keep.

What Is a Vacuum Truck?

A vacuum truck, sometimes called a vacuum excavator, vac truck or hydrovac, is a truck-mounted machine that uses powerful suction to remove material from the ground or from a tank, pit or pipe. That material might be soil, slurry, liquid waste, sludge, sand or debris.

At its simplest, a vacuum truck combines three things: a way to loosen or break up the material, a high-powered vacuum to suck it up, and a tank to store it until it can be disposed of or reused. The result is a machine that can dig a precise hole, clear a blocked drain, empty a flooded pit or clean out an industrial tank, all without a person ever needing to swing a pick or a digger bucket into the ground.

The big advantage is control. Because the material is loosened gently and drawn away through a hose, a vacuum truck can work safely around fragile and dangerous underground assets such as gas mains, power cables, water pipes and fibre-optic lines. This is why the method is known as non-destructive digging, or NDD.

How Does a Vacuum Truck Work?

Behind that simple idea sits some genuinely clever engineering. To understand how a vacuum truck works, it helps to know its main parts.

The Key Components

Every vacuum truck shares a handful of core systems. The vacuum source is the heart of the machine, usually either a positive displacement blower, which generates strong suction even at depth, or a fan system, which moves a very high volume of air for lighter material. The debris tank, also called the spoil tank, stores everything the truck draws up and can typically be tipped to offload the contents.

A water tank and high-pressure pump supply the water used to cut soil or jet a pipe clean, while air excavation units carry a compressor instead. A boom, which is an articulating arm, positions and supports the large suction hose, often 150 millimetres or more across, so the operator can direct it precisely. Finally, a series of cyclonic separators and filters strip fine particles out of the airflow so the blower is protected and the air leaving the truck is clean.

The Excavation Process Step by Step

When a vacuum truck is used to dig, the process is straightforward and quick. First, the operator uses either pressurised water or compressed air through a lance to break up and loosen the soil at the dig site. As the soil turns to slurry, or in the case of air, loose dry spoil, the vacuum draws it up through the suction hose and into the debris tank. 

The operator works steadily, exposing whatever lies below, whether that is a buried pipe, a cable or simply the bottom of a planned trench. Once the tank is full or the job is done, the spoil is transported away for disposal or, in the case of dry excavation, often reused as backfill.

The Main Types of Vacuum Trucks

Not all vacuum trucks are the same. The right machine depends on the material being removed and the conditions on site. Here are the main types you are likely to come across.

Hydro Excavation Trucks

Hydro excavation trucks, often called hydrovacs, use a jet of pressurised water to cut and liquefy the soil into a slurry, which the vacuum then removes. Water is highly effective at breaking up most soil types, including the compacted and clay-heavy ground found in parts of Perth, which makes hydro excavation the most common method for digging and potholing.

Air Excavation Trucks

Air excavation trucks use compressed air rather than water to break up the ground. The big benefit is that the spoil stays dry, so it can often be vacuumed up and then put straight back into the hole as backfill, with no slurry to cart away or dispose of. Dry excavation is ideal where keeping the soil reusable matters, and it is a popular choice for exposing sensitive utilities.

Combination Jet-Vac Trucks

Combination trucks, also known as jet-vac units, pair a high-pressure water jetting system with vacuum recovery. The jet blasts grease, sediment, roots and blockages loose inside a pipe or pit, while the vacuum immediately draws the debris and dirty water away. These are the workhorses of drain, sewer and stormwater cleaning, because they clean and clear in a single pass.

Wet and Dry Vacuum and Industrial Loaders

At the heavier end sit wet and dry vacuum trucks and industrial vacuum loaders, built to handle large volumes of liquid, sludge or dry bulk material. These machines are used for industrial tank cleaning, liquid waste removal, spill recovery and clearing material that ordinary equipment simply cannot manage.

Vacuum Truck Types at a Glance

Each type suits a different job, and a capable fleet covers all of them.

What Are Vacuum Trucks Used For?

The flexibility of vacuum trucks means they turn up across a huge range of jobs. These are the ones we handle most often across Perth and wider Western Australia.

Non-destructive digging and utility exposure is the headline use. Before any construction or excavation, underground services need to be located and physically exposed, a process called potholing or daylighting. A vacuum truck does this safely, removing the soil around a cable or pipe without touching it.

Drain and sewer cleaning is another major application. Using combination jet-vac trucks, we clear blocked drains, scour grease and roots from sewer lines, and flush stormwater pipes back to full capacity. Stormwater pit and soakwell cleaning falls into the same category, clearing out the sand, silt and leaf litter that build up and cause flooding once heavy rain arrives.

Vacuum trucks also handle liquid and slurry waste removal, emptying pits, sumps, interceptors and tanks quickly and cleanly. We use them for garnet waste removal, recovering the spent abrasive garnet left behind by waterjet cutting and abrasive blasting, which can then be disposed of or recycled. 

They are ideal for car wash bay and mud pit cleaning, where wash water, mud and sediment have to be captured and removed rather than washed into the stormwater system. And when the weather turns, the same trucks provide emergency flood response, pumping and vacuuming water away from properties and infrastructure fast.

Why Vacuum Excavation Is the Safer Way to Dig

The biggest reason vacuum trucks have taken over so many jobs is safety. Striking an underground service with a mechanical excavator can be catastrophic, causing gas explosions, electrocution, injuries, widespread service outages and very expensive repairs.

Vacuum excavation removes that risk. Because the soil is loosened gently and drawn away by suction, the operator can expose a live cable or a pressurised gas main without damaging it. This is exactly why utilities and regulators recommend it. 

Western Power, for example, defines non-destructive digging as breaking up the ground with high-pressure air or water and removing it with a powerful vacuum unit, and lists potholing as a core step in safe excavation near its network.

It all starts with knowing what is underground in the first place. Before any digging, a free enquiry should be lodged with Before You Dig Australia, which provides plans showing the location of registered pipes and cables on site. 

A vacuum truck then exposes those services precisely, confirming their exact position and depth before the main works begin. The combination of accurate plans and non-destructive digging is what keeps people, infrastructure and projects safe.

Beyond safety, vacuum excavation is precise, creates far less surface damage, and means less reinstatement afterwards. It is often faster than hand digging and far gentler on the surrounding ground than a mechanical bucket.

Frequently Asked Questions

What is the difference between hydro and air vacuum excavation?

Hydro excavation uses pressurised water to cut the soil into a slurry, which is then vacuumed up. Air excavation uses compressed air instead, keeping the spoil dry so it can often be reused as backfill. Water works well in most soils, while air is preferred where dry, reusable spoil is an advantage.

Is vacuum excavation safe around gas and power lines?

Yes, that is its main purpose. Because the soil is loosened gently and drawn away by suction rather than struck with a blade, a vacuum truck can expose live cables and pressurised pipes without damaging them. It is the method utilities and regulators recommend for working near underground assets.

What can a vacuum truck suck up?

A vacuum truck can remove soil, slurry, sand, sludge, liquid waste, sediment and many other materials. The exact capability depends on the type of truck and its suction system, which is why a varied fleet matters for handling different jobs.

Do I still need to contact Before You Dig?

Yes. Lodging a free Before You Dig Australia enquiry gives you plans showing where registered services are located. A vacuum truck then exposes those services precisely. The two work together, plans tell you roughly where to look, and non-destructive digging confirms the exact location safely.

Are vacuum trucks only for big construction sites?

No. While they are essential on major civil and mining projects, vacuum trucks are just as useful for residential and commercial work, such as clearing a blocked stormwater drain, cleaning soakwells, emptying a pit, or exposing a service before a small build.

Do you provide emergency vacuum truck services in Perth?

Yes. We provide fast call-outs across Perth and wider Western Australia, including emergency flood response and urgent drainage and liquid waste jobs that cannot wait.

Conclusion

Vacuum trucks have transformed the way we dig, clean and clear. By swapping a digging blade for powerful suction, they remove material precisely and safely, protecting the maze of pipes and cables buried beneath every Perth street. From hydro and air excavation to combination jet-vac and heavy industrial units, each type has its strengths, and the key is matching the right machine to the work in front of you.

Whether you need utilities exposed before a build, a stormwater system cleared before the rain, or liquid waste removed from a commercial site, a vacuum truck is almost always the safer, cleaner and smarter choice.
