Project Overview

The project comprises of a new water infrastructure to improve the water supply for the town of Trangie, approximately 35km west of Narromine. This project involves the construction of the following infrastructure as per design supplied:

Narromine Shire Council drilled three new water supply production bores in the township of Trangie and the project involved the fit out of these three new town bores and their connection into the to be constructed new rising main to each bore site. The project included design supply and installation of bore pumps associated electrical control and monitoring equipment. The project was undertaken through funding made available through Restart NSW Water Security for regions program.

Works Undetaken
