There are many benefits which will be realised during and after the construction of this project. Key benefits driving the project include:
- dam storage capacity will be increased by 53 per cent
- approx. 21 gigalitres per annum additional estimated yield for general security license use
- a significant improvement in:
- water security
- drought resilience
- flood attenuation for the Lachlan Valley
- local business and employment opportunities maximised throughout the project.
The Wyangala Dam wall raising is expected to:

- provide greater certainty of water reliability to support additional investment by businesses, particularly in the agricultural sector, including:
- transitioning to higher yield agricultural products
- increasing stock levels.
- secure the region’s town water supplies, stimulating the growth of the regional economy and supporting future population growth.
Early works package: new water treatment plant at Wyangala
As the early works package to the proposed Wyangala Dam Wall Raising project, a New Water Treatment Plant will be built to deliver clean, safe drinking water for the Wyangala community and Wyangala Waters Holiday Park.
The new water treatment plant is being delivered as a ‘no regrets’ project as it is separate from the wall raising construction and brings local benefits.
A development application for the new water treatment plant was approved in December 2021. The team began work site set up in February 2022 with construction work to start shortly after.
Construction and commissioning of the new plant is expected to about 12 months, public health orders and restrictions permitting.
