About

Safe, non-destructive
digging for all site conditions

Dig through soil in minutes, not hours, with Cleanaway’s hydro excavation services – the faster, safer and more sustainable alternative to mechanical digging.

Hydro excavation, also known as non-destructive digging (NDD), combines pressurised water with a high-powered vacuum system to break up and remove soil. The pressure mimics the effect of mechanical digging, but because the water is focused on the target, it doesn’t impact the surrounding area. It’s this control and precision that makes hydro excavation the safest way to expose underground assets and dig around critical infrastructure like pipes and cables without causing damage.

Supported by a fleet of purpose-built vacuum excavation units and a team of trained operators, Cleanaway delivers fast, compliant and environmentally-friendly hydro excavation services across Australia.

Soil and slurry waste

Hydro excavation produces a slurry of loosened soil and water from potholing, trenching and utility locating. This slurry can include clay, sand, gravel and organic matter that requires safe collection and transport.

Contaminated excavation spoil

In industrial and urban settings, excavation may release contaminated soils containing hydrocarbons, asbestos-containing debris, PFAS or other regulated substances. These wastes require specialist handling and traceability.

Expertise

Versatile industrial digging solutions

Hydro excavation is a safe, quiet and controlled method for digging, trenching and locating infrastructure beneath the surface, making it well-suited to a range of applications. This includes:

Potholing and utility locating

Expose underground services like gas, water, sewer and telecommunications lines without damaging them

Safe trenching
Create clean, narrow trenches for pipes or cables
Signpost and pole installation
Safely dig small, precise holes in urban or remote locations
Under-road or footpath digging
Excavate in sensitive areas with minimal disruption
Pipeline and drainage access

Expose or clear blocked infrastructure safely

Root barrier and tree protection works

Dig near vegetation without damaging roots

Benefits of hydro excavation

Hydro excavation offers several advantages over mechanical digging tools like jackhammers, drills and excavators:

Reduced risk

Digging speed, depth and area can be controlled more easily, minimising the risk of damaging pipes, cables and utilities beneath the surface

Environmentally safer

Reduces ground disturbance and prevents contamination, with the slurry reused as backfill where possible to reduce waste

Better precision

The greater accuracy of hydro excavation makes it ideal for confined spaces, sensitive sites and live facilities

Cost efficiency

Non-destructive digging works faster and generates less mess to clean up, reducing time on the job and project costs

Process

How Cleanaway’s hydro excavation services work

Our hydro excavation services are compliant with all industry and environmental standards, ensuring safety and sustainability is built into every stage of the process.

Site assessment

We work with you to understand your site conditions and safety needs.

Mobilisation

A Cleanaway vacuum excavation unit arrives onsite with trained operators.

Pressurised water injection

High-pressure water is used to loosen and break up soil.

Vacuum extraction

Dislodged soil and debris is sucked up with a powerful vacuum hose and stored in the hydro vac tank.

Disposal or reuse

Once repairs or construction are complete, the collected soil slurry can be returned to the hole, or if contaminated, disposed of at EPA-licensed facilities.

Details

Equipment and fleet

Cleanaway operates a national fleet of industrial-grade hydro excavation trucks that are equipped to handle any digging or trenching job.

Vehicle and equipment features:

Combination high-pressure water jetting and vacuum loading units

Onboard spoil tanks for liquid or slurry collection

Hoses with high water pressure ratings for hard ground, and adjustable pressure controls to protect underground assets

Remote or confined-space capable equipment

Compliant with site access and safety requirements

 

Output

What happens to waste

The soil slurry generated during hydro excavation is stored in sealed tanks and either returned as backfill if uncontaminated, or processed through Cleanaway’s facilities if unsuitable for reuse. This approach reduces waste and keeps worksites clean and safe.

Where excavation uncovers contaminated spoil such as hydrocarbons, asbestos-impacted material or PFAS-affected soils, these are transported to EPA-licensed facilities for treatment or secure disposal. Full documentation ensures compliance with regulatory requirements.
