Projects around Auckland

Central Interceptor project

At any one time we have multiple projects happening across Auckland. Click here to learn about our projects that will reduce overflows.
 

The Central Interceptor

We’re building a super-sized wastewater tunnel that will reduce wastewater overflows into central Auckland creeks and streams. The 4.5m internal diameter tunnel will be 14.7 kilometres in length and run from Grey Lynn to our Māngere wastewater treatment plant. We have several construction sites across the isthmus, with tunnel boring well underway.
