Western Duplication

​​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 interceptor (large wastewater pipe) project.  Recently our team completed the pipe installation under Mangaharakeke Dr (SH1) which was done using a tunnel boring machine – click here to see some cool pictures of the tunnelling process.

We've also finished another section of the interceptor – on the west side of Mangaharakeke Dr (SH1) - which has now been connected up to an existing large wastewater pipe (Far Western Interceptor).

Now, the team has moved across the road – near Fonterra – to start work on the another two sections of pipe. These sections will run along Crawford St up to the roundabout. This work is expected to be completed early 2021.​

We appreciate your patience during this time.

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