Western Wastewater Interceptor (wastewater pipe)

​​​Why are we doing this? ​

We are investing $2B in the city's biggest-ever 10-Year capital programme which will set the platform for planned, susta​inable growth and to look after Hamilton's future transport, strategic infrastructure and community facilities. 

We are ensuring we have the provisions in place for essential wastewater services that allow for future growth and compliance. A major project enabling us to do this is the Western Interceptor (large wastewater pipe). Installing this pipe will enable continued development in Hamilton west and increase resilience in our city's wastewater network. The project involves installing approximately 2.4km of new wastewater pipe underground along the Avalon Bypass which will then connect to our Pukete Wastewater Treatment Plant.​

Latest project update...

Good progress has been made on the pipeline, with the team completing installation under Mangaharakeke Dr (SH1) using a tunnel boring machine. We're currently working along Mangaharakeke Dr (SH1) and expect to reach Forest Lake Road by Christmas with installation expected in the New Year.

Before the team can install the pipeline an existing watermain needs to be moved. The northern shoulder of Forest Lake Road (including the footpath between Rimu Street and Avalon Drive intersection) will close in early November for approximately two to three weeks while the works are underway.

We appreciate your patience during this time.

This project has been funded in the 2018-28 10-Year Plan to a value of $22M. ​
