The NSW Government has announced it is moving ahead with critical water and wastewater works to support housing growth in the community of Wilton.
Wilton Stage 2 will enable water and wastewater services for about 4,000 new homes in the area, doubling the total servicing capacity across Wilton to around 8,000 homes and businesses.
This investment builds on major work already under way, ensuring essential water and wastewater infrastructure keeps pace with population growth, allowing more families to move to one of the state’s key growth areas.
Sydney Water has already begun construction in Wilton Stage 1, which is upgrading the existing Wilton Water Resource Recovery Facility and building new pumping stations, reservoirs and pipelines.
In another major delivery milestone, Sydney Water has awarded Haslin Constructions the contract to upgrade the Wilton Water Resource Recovery Facility.
The upgrade will significantly increase local wastewater treatment capacity to support future growth while helping reduce truck movement through the area.
Stage 2 is now in the early planning and design phase with planning and pre-delivery activities under way, including partnering with NSW Government property developer Landcom on its North Wilton development.
Stage 1 works, pictured below, are on track for completion at the end of 2027.

“We are making sure water and wastewater services keep pace with demand, giving thousands more families an opportunity to call Wilton home,’’ said NSW minister for water Rose Jackson.
“We need and want more homes, but they can’t be built without the essential pipes and pumps that support them.’’
One key stakeholder that was ecstatic with the government’s announcement was Wollondilly Shire Council.
“Wilton is a fantastic community that is growing quickly. I am pleased to see this essential infrastructure being provided by Sydney Water to support this growth and ensure certainty for our residents,’’ said Mayor Matt Gould who attended last Friday’s announcement.
“This will address water and sewer issues in Wilton so that this community will have this essential service in place and mean some areas will no longer have to rely on trucks to collect and transport their sewerage out of the area,’’ he said.
