Liverpool Plains Shire Council, in collaboration with Federal and NSW governments, have built a new state-of-the-art water treatment plant at Quipolly. The plant will treat water from Quipolly Dam and via the new pipeline will supply water to the Werris Creek and Quirindi communities.

The Council has worked closely with the Federal and State Governments to attract funding to the amount of $25 million for this project.  At this stage, it is estimated that the project will cost $32.4 million with Council making a contribution of up to $7.4 million to complete the project.  

Across the region, once completed the Liverpool Plains Shire Council’s new water treatment plant, located at Quipolly Dam, will be able to produce more than
6 million litres of high-quality drinking water per day through a state-of-the-art treatment process.

This project will secure the Werris Creek water supply and provide options for the management of Quirindi water supply by constructing a state of the art water treatment plant near Quipolly Dam and a pipeline to Werris Creek and Quirindi.


This partnership project will provide improved water quality with a secure system that meets the needs and growth of the Liverpool Plains Shire now and into the future.

This project is now in its final commissioning stages.

Liverpool Plains Shire Council, working together with Beca HunterH2O, Gongues Constructions and GHD, have been project managing, designing, constructing and testing this critical project, which will enable the treatment of up to 6 million litres of water treated to modern standards and distribution to Werris Creek, Quirindi, Willow Tree and the surrounding areas. The improvement to resilience of the supply will provide health and economic benefits to these regional communities.


The scheme comprises dam works, a treatment plant, approximately 20km of pipelines,  reservoirs, electrical upgrades and related infrastructure that have been the subject of planning and complex engineering for several years. Construction commenced late 2021 and the team is now in the final throes of testing and optimisation of the works, with excellent treatment results being achieved.
