We’re working to reduce wastewater overflows and keep our environment cleaner.
We are working on two wastewater projects that will help us to reduce wastewater overflows in the environment and keep up with growth in central and north west Auckland.
The Northern Interceptor is a new wastewater pipe being built in stages. This will take wastewater that is currently going to the Māngere Wastewater Treatment Plant and redirect it to the Rosedale Wastewater Treatment Plant. The Rosedale plant can process more wastewater and cater for growth in the north-west.
The first stage of the Northern Interceptor pipe has been built between the Hobsonville wastewater pump station and the Rosedale Wastewater Treatment Plant.
The Central Interceptor, which is currently being built, will significantly reduce wet-weather overflows and help keep Auckland's beaches clean.
It will carry combined wastewater and stormwater from central Auckland to the Māngere Wastewater Treatment Plant, using the treatment capacity freed up by the Northern Interceptor.
