Central Interceptor

December 2, 2021 by

The Central Interceptor is a major wastewater tunnel being constructed in Auckland, New Zealand.

AWMA has been engaged by head contractor, Ghella Abergeldie Joint Venture and their client Watercare.

AWMA were required to custom design, manufacture and supply a range of regulating and isolating water control structures.

The Central Interceptor tunnel will run underground for 14.7km. Travelling from Grey Lynn to the Māngere Wastewater Treatment Plant, the tunnel will pass multiple shafts and chambers being constructed as part of the project to connect the existing waste water systems.

AWMA’s contribution involves the specialised design, manufacture and supply of gates to be installed in the control and diversion chambers and shafts along the route, which will be used for collecting and transferring wastewater into the tunnel.

The wastewater control gates currently progressing through AWMA’s design and engineering phase include hydraulically actuated slide gates, electrically actuated slide gates, stoplogs, stop plates and flap gates.

All water control gates will be manufactured from Duplex 2205 and 2507 stainless steel for strength and longevity in the highly corrosive environment.
