New Water Quality Management Facility at Aspley Reservoir to Improve Water Security

Seqwater is one of Australia’s largest water businesses with a geographically spread and diverse asset base of any capital city water authority. Seqwater delivers a safe, secure and reliable water supply to south east Queensland, as well as providing water for irrigation to about 1,200 farmers, essential flood mitigation services and managing catchment health.

Construction of a new water quality management facility and modification to the underground pipelines at the Aspley Reservoir site will improve the reliability of Seqwater bulk water infrastructure, boost the disinfection of treated water travelling from Brisbane with the ability to respond during times of extreme weather.

AVK Valves were successful in supplying 3x AVK Series 756 Double Eccentric Butterfly Valves with valve sizing’s of 1x DN1050, 1x DN1400 and 1x DN1600. These valves required specialised drilling patterns, coatings and materials to conform with the stringent specifications of the project in which AVK Valves were able to productively modify the existing Series 756 to satisfy the needs of Seqwater. 

The valves were delivered to site and connected to pre-fabricated pipe lengths to minimise down time during installation. Operated by electric actuators, these units were retrofitted following the completion of pipe installation. Whilst the largest of these units was DN1600, AVK Valves manufacture the 756 series up to and including DN3000. AVK Valves were also able to assist Seqwater with the required short lead time for the delivery of the valves to ensure that necessary shut downs were undertaken during low demand periods.
