Amaroo Main Sewer Isolation Bulkhead

February 20, 2018 by

AWMA were engaged by the John Holland Group to supply a purpose-built isolation bulkhead for Yarra Valley Water’s Amaroo Main Sewer Project.

The Amaroo main sewer is a gravity sewer pipe, with an internal diameter of 1.6m, constructed up to 20 meters below ground level.

To provide isolation of the main sewer, AWMA custom engineered a round bottom, wedge-style bulkhead gate with an integrated equalisation valve to allow operation under flow conditions.

Manufactured from grade 316L stainless steel materials and utilising accredited continuous welding techniques, ensures the gate can withstand corrosive environments with minimal maintenance required.

To install the bulkhead, operators use an appropriate lifting device to lower the gate into position along a rebate channel, forming a wedge tight seal. When not in use the bulkhead is completely removed from the environment and securely stored.

AWMA’s isolation bulkhead gate measures 2m high x 1.8m wide and was successfully tested to 20m off seating head pressure.
