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.

Roma West 2B Gathering Project

This particular section included gas and water gathering pipelines, along with the added complexity of installation of HV & FOC reticulation, often commingled within the trenches with the PE Gas & Water pipelines.

Pneumatic testing was progressively completed in five defined sections, allowing a sequenced handover of the asset to commence early gas extraction.

Completed on time and on budget, with zero defects, despite significant challenges of slow rock excavation and inclement weather.
