The Central Interceptor

A supersized wastewater tunnel that will reduce overflows onto beaches and into waterways by up to 80 per cent. The project is well underway at various sites across Auckland, and once complete it will run underground from Grey Lynn to our Māngere Wastewater Treatment Plant.
