Purpose-built NDD vac trucks for safe, non-destructive excavation around buried utilities.
Compact units that fit through 900mm gates, servicing all of greater Sydney.
An NDD vac truck is a specialised piece of mobile plant built from the ground up for non-destructive digging. Unlike a standard excavator that relies on a steel bucket to tear through soil, an NDD vac truck uses two integrated systems mounted on a single vehicle: a high-pressure water lance and an industrial-grade vacuum unit connected to a sealed spoil tank. The water jet loosens the earth at a controlled pressure, and the vacuum simultaneously extracts the wet slurry, leaving a clean and precise excavation with zero mechanical contact on buried infrastructure.
The key components of an NDD vac truck include a water pump capable of variable pressure output (allowing operators to adjust for soil type and proximity to services), a high-flow vacuum blower or fan system, a large-diameter suction hose, a spoil tank ranging from 500 litres on compact units to several thousand litres on full-size rigs, and an onboard fresh water supply. More advanced NDD vac trucks also feature boom-mounted suction arms, remote controls for single-operator use and hydraulic rear doors for fast spoil discharge.
Pro Expose Hydro Vacs operates compact NDD vac trucks purpose-built for Sydney's tight access environments. Our units deliver the same excavation performance as full-size machines but within a footprint narrow enough to pass through a 900mm residential side gate. This means we can bring the NDD vac truck directly to the dig zone rather than running long hose lengths from the street, which reduces setup time and improves suction efficiency on every job. The same compact rigs run our hydro vac truck and vacuum excavation service across Sydney.
Regulatory standards and asset owner rules that mandate NDD vac truck use on Sydney worksites.
An NDD vac truck is required whenever excavation work falls within the tolerance zone of buried utilities. Australian Standard AS 5488. Classification of Subsurface Utility Information establishes that physical exposure of underground assets must be performed using non-destructive techniques. In practical terms, this means an NDD vac truck is the only compliant piece of equipment for verifying the position, depth and condition of buried services before major ground works begin.
Safe Work Australia's Code of Practice for Excavation Work reinforces this by prohibiting mechanical excavation within the defined clearance distance of any marked utility. Within this zone, only hand digging or an NDD vac truck may be used. Given that hand digging is slow and labour-intensive, an NDD vac truck is the default choice for commercial and civil projects where productivity and safety must be balanced.
Sydney's major utility companies impose their own NDD vac truck requirements. Jemena mandates non-destructive excavation for all work near gas infrastructure. Ausgrid and Endeavour Energy require an NDD vac truck for cable location and joint bay excavation. Sydney Water specifies non-destructive methods near pressurised water mains and sewer assets. NBN Co and Telstra require NDD for any excavation that could affect their fibre and copper networks.
Failure to use an NDD vac truck where required can result in service strikes, costly emergency repairs, regulatory penalties, project delays and liability for outages that affect the public. Every NDD vac truck job performed by Pro Expose Hydro Vacs is fully Dial Before You Dig compliant, and our operators carry current certifications for safe excavation near all utility types.
Why an NDD vac truck is the only safe option when underground services are present.
The bottom line: wherever underground services exist, an NDD vac truck is the only equipment that delivers both safety and compliance. Mechanical excavators have their place on greenfield sites with no buried assets, but in Sydney's densely serviced urban environment, an NDD vac truck should be the first call for any excavation project. Pro Expose Hydro Vacs runs its own compact NDD vac truck and arranges additional units through our vetted Sydney operator network, ready for same-day dispatch across the entire Sydney metropolitan area.
Purpose-built compact NDD vac trucks operated by experienced, certified professionals.
From major utility providers to residential plumbers, NDD vac trucks serve every sector that excavates near buried services.
Civil construction contractors are among the most frequent hirers of NDD vac trucks in Sydney. Road widening, footpath renewals, kerb and gutter replacement, light pole installation and stormwater drainage upgrades all require excavation in road reserves where gas, water, power and telecommunications assets converge. An NDD vac truck allows civil crews to dig safely without shutting down services or risking strikes that halt the entire project.
Residential builders and renovators hire NDD vac trucks for house extensions, granny flat builds, swimming pool excavations and landscaping projects. In established Sydney suburbs, even a small backyard can have gas, water, sewer, power and telecommunications lines running through it. A compact NDD vac truck locates and exposes these services safely before any structural excavation begins, preventing costly damage and project delays.
Telecommunications companies including NBN Co, Telstra and Optus hire NDD vac trucks for fibre rollouts, pit and conduit installation, fault rectification and capacity upgrades. A single fibre optic cut can disconnect thousands of premises, so NDD is the only excavation method their specifications permit near active telecommunications infrastructure.
Plumbers, electricians and utility subcontractors use NDD vac trucks daily across Sydney. Whether it is exposing a sewer connection for a bathroom renovation, finding a water main for a new tap installation, or locating buried power conduits before trenching for a new circuit, an NDD vac truck completes the job in minutes compared to hours of careful hand digging. Combined with professional underground service locating, an NDD vac truck provides complete certainty about what lies beneath before a single pipe is laid or cable is pulled.
Common questions about hiring an NDD vac truck in Sydney.
An NDD vac truck is a specialised vehicle designed for non-destructive digging. It combines a high-pressure water system with an industrial vacuum unit and a sealed spoil tank, all mounted on a single truck chassis. The water lance breaks up soil while the vacuum simultaneously extracts the slurry, allowing operators to excavate around buried utilities without any risk of damage from mechanical contact.
You need an NDD vac truck whenever excavation is planned near known or suspected underground services. Australian Standard AS 5488, Safe Work Australia codes of practice and Sydney utility owners such as Jemena, Ausgrid, Sydney Water and NBN Co all require non-destructive methods within the tolerance zone of buried assets. An NDD vac truck is also required for potholing, service verification, trenching near utilities and any Dial Before You Dig compliant excavation.
NDD vac truck hire in Sydney is typically charged at an hourly rate that includes the truck, a qualified operator, water supply and spoil removal. Final cost depends on job duration, number of excavation points, soil conditions and site access. Pro Expose Hydro Vacs provides upfront quotes with no hidden charges.

A mechanical excavator uses a steel bucket with hardened teeth to rip through soil, which can sever gas mains, rupture water pipes and cut electrical or fibre optic cables. An NDD vac truck replaces that mechanical force with pressurised water and vacuum suction, producing zero contact with buried infrastructure. The result is a safer, cleaner and more precise excavation with no risk of service strikes.
Yes. Pro Expose Hydro Vacs operates compact NDD vac trucks specifically built for tight access work. Our units fit through standard residential side gates as narrow as 900mm and can work in confined backyards, narrow laneways and restricted commercial sites where full-size vacuum trucks and excavators cannot physically enter. This makes our NDD vac truck ideal for residential renovations and backyard projects in Sydney.
