New water infrastructure is to be built on the east bank of the Kiewa River, downstream of the Pondage spillway on Embankment Drive. This new ‘offtake’ will allow water from the Kiewa River to be pumped to the Mt Beauty treatment plant in Tawonga South before it is returned back into the community as drinking water.
The proposed works will consist of a small weir in the West Kiewa River to ensure adequate water levels during low flow periods, a fish passage structure, a pump station located in a building adjacent to the river, and a new pipeline along Embankment Drive to connect to the existing water supply pipe to the water treatment plant.
This site is the best location for uninterrupted water extraction as it is downstream of AGL operations and has guaranteed river flows. The site also has a low risk of being affected by bushfire and flooding, good access to the existing raw water main, low environmental impact during construction and is the best option for the safety of our staff.
Since our last community newsletter in September 2019, we’ve been progressing the project despite the challenges of 2020. This includes the below:
- We have completed a geographical survey of the site and verified the area is suitable for the new infrastructure.
- Our engineers have been working on the design of the offtake including pipework and a pump station. They have determined that a weir will be needed to allow enough water to pool near the offtake during low flows. The weir wall will also include the construction of a fish ladder.
- We have been working with the relevant authorities to gain the necessary construction approvals.
