The Central Interceptor is coming

Over the next 6 years we’re building the Central Interceptor to help make our waterways in central Auckland cleaner. The Central Interceptor will run underground from Western Springs, near the Auckland Zoo, to the Māngere Wastewater Treatment Plant. It will have several link sewers and shafts along the route for collecting and transferring wastewater into the tunnel.

Our contractor

Ghella Abergeldie Joint Venture (GA) is building the Central Interceptor. GA has more than 150 years’ experience with tunnelling and wastewater projects of this size across the globe.
