In October 2019 the Prime Minister and NSW Premier announced the planning and delivery of three new or augmented dams in NSW. Included in this package was the raising of Wyangala Dam wall to improve water security and drought resilience in the Lachlan Valley.
The Wyangala Dam Wall Raising is estimated to cost $650 million and increase storage by 53% by creating capacity for an additional 650 gigalitres. The project will involve raising the dam wall by around 10 metres, with the exact height and new full supply level to be confirmed throughout the next six to nine months as further detailed investigations, technical assessments and site inspections are undertaken.
The project has been classified as Critical State Significant Infrastructure and it will be delivered on an accelerated timeline while still meeting all the necessary planning requirements.
Local landholders who may potentially be affected by the project have been contacted recently and environmental assessments are underway despite the Coronavirus pandemic.
Water NSW is encouraging local businesses to register their interest in providing services to the Wyangala Dam Wall Raising project.
If you own or operate a business in the local region and can offer relevant services and products, let Water NSW know your details and they will share these with the project partners, contractors and consultants. To register your business interest visit www.waternsw.com.au/wyangalabusiness
Shovels should be in the ground for ancillary works by October 2020 with the major construction works to commence by October 2021.
