Hydro Excavation
Non-destructive digging with 6,000L and 8,000L vacuum units — expose, clean and maintain without damage.
We dig without destroying.
C&S Drainage Contractors delivers advanced hydro excavation — the safest, most precise way to excavate around sensitive underground utilities and infrastructure. High-pressure water breaks up the ground while a powerful vacuum removes it immediately, exposing services with clear visibility and zero impact damage.
Our purpose-built 6,000L and 8,000L hydro excavation units handle non-destructive digging (NDD) around electrical cables, gas lines, telecommunications and water utilities, and double as a full pipeline maintenance capability — cleaning drains from 90mm to 1800mm, jetting blockages and vacuum-loading sumps and pits.
Delivered by our dedicated CS Hydrovac Excavation division.
Hydro excavation runs as its own division — purpose-built 6,000L and 8,000L units, NDD utility locating and drain cleaning from 90mm to 1800mm, operated across the Pilbara.
What the scope covers.
Non-destructive utility location
Precision excavation around electrical cables, gas lines, telecommunications and water utilities where mechanical digging poses unacceptable risk — clear visibility of services without physical contact.
Critical infrastructure
Accurate location verification and clean excavation with minimal site disturbance around fibre optics, high-pressure gas lines and electrical distribution — in urban environments and on industrial sites.
Pipeline & drain maintenance
High-pressure water jetting to clear blockages, remove sediment and restore full flow capacity across the 90mm–1800mm range, plus vacuum cleaning of sumps and pits and emergency response for blocked or damaged systems.
Industrial & municipal
Routine maintenance of municipal drainage systems through to specialised industrial cleaning — supporting councils, government agencies and private industry on planned programs and emergencies.
The equipment
Adjustable high-pressure water systems for different soil conditions, powerful vacuum systems for immediate debris removal, and precision controls for working safely around the most sensitive assets.
Safety & compliance
Comprehensive utility location before excavation, coordination with utility owners and authorities, environmental protection of excavated material, and detailed documentation of every exposed asset.
