Hoxton Park Recycled Water Scheme

Hoxton Park Recycled Water Scheme

Client: Lendlease

Asset Owner: Sydney Water

Project description

As part of the South West Growth Area plan, Sydney Water devised a recycled water scheme. The total project value of more than $100 million had the John Holland Group oversee close to $40 million of groundwork for piping and the construction of large reservoirs around Hoxton Park and Edmondson Park.

Lend Lease was awarded work laying about 30 kilometres of underground piping for the project.

The following construction works for the project involved.

Recycled Water Treatment plant at Glenfield STP

Recycled water pump station at Glenfield STP

Recycled water reservoirs at Edmonson Park & Hoxton Park

Up to 30km of recycled water pipelines

Killard Infrastructure was one company subcontracted by Lendlease to lay dual DN450 and DN375 pipelines between the recycled water treatment plant and the reservoirs to carry both treated and untreated water. Pipe was stored at the STP which required detailed transport planning, co-ordination and movement.

Mr. Victor Farrugia



The project was hailed as one of the largest environmental infrastructure projects in the country

The project demonstrated our experience working with both mild steel and ductile iron pipe.

We also engaged collaboratively with a Tier 1 Contractor whose client (Sydney Water) is one of the leading statutory authorities in Australia. In addition, there was a high degree of community consultation as well as business to business co-ordination involved around other infrastructure projects in the region, at that time.
