When Sydney Water began the process of upgrading the Quakers Hill Sewage Treatment Plant, AVK was the supplier of choice when it came to valves.

The Quakers Hill Sewage Treatment Plant is located north-west of Sydney. This plant is the second largest in Sydney and is responsible for 32 megalitres per day of tertiary treated effluent.

In August 2011, Sydney Water approved a $57 million upgrade to the facility to increase the output and to eliminate any overflows.

AVK Australia was pleased to be a supplier for the new pump station at Quakers Hill. AVK supplied 12 150mm AVK ball check valves to be attached to the 600mm inlet pipe manifold.

The extraordinary thing about these ball check valves is the way they are installed onto the manifold. The valves are installed vertically so the valve will remove the air from the manifold at pump start-up, allowing the sewage fluid to flow into the treatment plant. This unusual application of AVK ball check valves was established by extensive consultation between AVK and the SewerFix Wet Weather Alliance to ensure the flow rates complied with Sydney Water’s increased flow requirements.

The AVK valve released the air at a velocity of 15m per second into the return pipeline storage tank location. The valves are able to remove all the air at pump start-up within 20 to 30 seconds. With pump start-up occurring 10 to 12 times over a 24-hour period, this was an important element to the successful operation of the plant.

The upgrade was completed in late 2013 and AVK was proud to be a part of this successful project.
