Background

Coorong Quays Pty Ltd (CQ) has recently taken ownership of the development and following considerable negotiation, at the Alexandrina Council meeting held on 20 August 2018 agreement was reached to transfer ownership & management of the Coorong Quays Community Wastewater Management Scheme to Alexandrina Council over a period of time.

To facilitate ultimate waste water flows from Coorong Quays residential development a number of Alexandrina Council wastewater network components require expansion, upgrade and/or new construction.

Coorong Quays WWTP to O'Connell Ave Pump Station, Transfer Main

Alexandrina Council currently owns and operates a wastewater pump station located within an undeveloped residential parcel of land on O’Connell Avenue, Hindmarsh Island. This existing pump station services a portion of Hindmarsh Island residents located upon O’Connell Avenue and Sturt Parade, Hindmarsh Island.

Waste water is then transferred via an existing pumping main over the Hindmarsh Island Bridge before discharging into the Vercoe Terrace DN225mm pumping main, and ultimately, the Goolwa WWTP.

A new dedicated pumping main is required to link the Coorong Quays WWTP to the O’Connell Avenue pump station. The new pumping main will provide a dedicated connection and be approx. 1300m in total length.

The Council is supportive of tenders considering and utilising the services of local suppliers, providers and trades for all aspects of the project. Tenders shall document those nominated specialists, suppliers and trades within their package and fee proposal.
