The Central Interceptor is a new wastewater tunnel proposed to run between Western Springs and the Mangere wastewater treatment plant in Auckland. The tunnel will be approximately 13 kilometres long and will lie between 15 and 110 metres below the surface. It will cross the Manukau Harbour at a depth of approximately 15 metres below the seabed. Along the proposed route, it will connect to the existing trunk sewer network to divert flows and overflows into the tunnel.

Auckland Council-owned utility Watercare is overseeing construction of the project. Construction is set to commence in 2019 and expected to be completed in 2025. Watercare is currently progressing detailed design of the project.
