Water/Wastewater
Our water delivery teams are highly experienced and authorised to work on water, wastewater and stormwater infrastructure projects for Sydney Water and private sector clients.
We are a Sydney Water Listed Provider (Constructor – Major Works) and can undertake work in the following categories:
- W1 – Water reticulation DN100-375
- W2 – Water supply DN > 375-750
- W3 – Steel pipelines DN > 750-1200
- RW – Recycled water DN 65-375
- S1 – Sewerage reticulation DN 150-300
- S2 – Sewer standard DN 375-75
- PE – PE pipe systems
Our project experience involves trunk main installations, main relocations, deep excavations, trenchless installations, temporary works solutions, bypasses and diversions, manholes, valves and pit constructions, water treatment plant works, pump station construction and fit-outs, and more.
We’re one of the few self-performing infrastructure and civil engineering companies in New South Wales. This means we use our own people and our own plant – we don’t subcontract key components of the work.
Our modern fleet of plant and equipment such as tippers, excavators, backhoes, skid steers and vacuum trucks, and our accredited systems result in lean, efficient and quality project outcomes.
“Our delivery teams consisting of engineers, operators and pipe layers, are highly regarded with years of experience working on Sydney Water assets.”
