Tender Description

⁠⁠⁠This contract is being procured as one of several contracts required to deliver, complete and commission the project. This Specification pertains to Package 7 (Pumping Station Upgrade, Electrical and Programming) works only.

Walcha has a population of approximately 3,100 people and is currently provided with reticulated water supply. Raw water is drawn from the Macdonald River (part of the Namoi River Basin) via an existing river offtake pumping station (ROPS) and transferred to the Walcha Water Treatment Plant (WTP) via a 16-kilometre-long DN225 pipeline.

In response to recently experienced periods of severe drought, Walcha Council are in the process of constructing a new 300 ML off creek storage (OCS1) reservoir, as well as undertaking significant upgrades to their existing pumping infrastructure.

The proposed upgrades to the existing River Offtake Pumping Station (ROPS) include augmentation of the existing offtake wharf and dry well structures, modification of the internal mechanical fitout of the existing dry well and replacement of the existing switchboard, suction pipework and delivery pipelines. These upgrades will allow the pumping station to fill OCS1 while simultaneously transferring flows to Walcha.

This contract is being procured as one of several contracts required to deliver, complete and commission the project. This Specification pertains to Package 7 (Pumping Station Upgrade, Electrical and Programming) works only.
