Project Value

Mitchell designed and constructed the project which included 20km’s of DICL DN450 pipelines with a 0.5ML balance tank. Works also included the conversion of an existing Wolumla Village reservoir to a balance tank for an ultimate transfer of 20ML/day of raw water from South Bega reservoir site to the inlet pipe-work into Yellow Pinch Dam. Flouride and Chlorine Dosing Equipment was also costructed at the Sough Bega Reservoir along with a 1ML reservoir at Wolumla.

The project was designed to improve the water supply security of the existing Tantawangalo-Kiah water supply system. It will also lessen extraction of water from Tantawangalo Creek and the Kiah Borefield during low stream flows by connecting a new source of water to the system and enhance operational flexibility in the supply of water from the sources and dams to customers.

A major challenge on the project from the outset was the resistance of several key Landowners to joining the scheme threatening to derail the project. Face to face meetings between the Landowners and Managing Director Wayne Mitchell established Landowner consent for the 40km of pipelines to be constructed through their properties, with access points omitted pending resolution of Water Authority issues.
