Throwback - Watercare: Central Interceptor Project - May Road Site

The Central Interceptor is a super-sized wastewater tunnel that will reduce overflows, creating a better environment for you to enjoy.

We visited the May Road Site and learned more about the Central Interceptor Project thanks to Marie Bonnaud and Antoine Foulon. 

  • Marie Bonnaud is a project engineer in the Watercare environmental team. During the last 2 years, she has been in charge of the environmental matters and community outcomes including leading the integration of art and the water sensitive design solutions for the site reinstatement.
  • Antoine Foulon is a senior project engineer. After 10 years in France working in surface works, Antoine jumped on a new challenge coming to NZ to work in tunneling on the Central Interceptor Project.

What is this Central Interceptor for?

Today, sewage is fully treated except when it rains and then some pipes overflow into our waterways, which isn’t nice for you or the environment.

The Central Interceptor is an integral part of Watercare’s long-term strategy to effectively manage wastewater within Tāmaki Makaurau, to protect public health and the environment and to provide for growth. 

The Central Interceptor will run underground from Western Springs, near the Auckland Zoo, to Watercare’s Māngere Wastewater Treatment Plant. It will have several link sewers and shafts along the route for collecting and transferring wastewater into the tunnel.
