The Wyong Shire Council in NSW decided to upgrade their pre-existing sewage treatment plant.
Wyong is situated on the central coast of NSW. The new inlet works structure was built to house the screening of the sewage and the grit removal. Inlet works were designed to be completely covered so the odour could be reduced especially for the local residents.
Leed Engineering won the contract to build the new works. AVK were successful in supplying the electrically actuated Penstocks. The Penstocks are used to isolate parts of the structure for maintenance and bypass purposes. Penstocks were manufactured by Orbinox AVK in Spain and were all 316 stainless steel given the waste product filtering through.
