The Project

This project was implemented to reduce the Council’s reliance on mains water for irrigation of its parks and reserves. When the scheme was initially drafted, Council was using over 1 GL/a of mains water for irrigation. 

Technical Solutions

WGA developed the concepts and managed the development of a sewer mining scheme consisting of two sewer mining pump stations. In addition, a wastewater treatment plant capable of treating 1.1ML per day of sewage to a standard suitable for residential reuse (log 6.5 virus reduction under the National Water Reuse Guidelines) was designed and installed to treat the effluent for reuse. WGA completed the feasibility study for the development of Council’s major harvesting site at Wynn Vale Dam through a media filtration plant. 

Client Focus

WGA was responsible for delivering the project plans, project management and certification for the scheme. WGA supported the incorporation of Council’s stormwater harvesting site at Wynn Vale Dam and associated managed aquifer recharge systems with the wastewater scheme to provide an integrated reuse design.

Approximately 22.5 kilometres of distribution ring main was installed to distribute the harvested water to various sites for municipal irrigation throughout the City of Tea Tree Gully.
