In June 2016 the NSW Government announced the Hawkesbury-Nepean Flood Risk Management Strategy (the Strategy) to reduce the potential flood risk to life, the economy and social amenity in the Hawkesbury-Nepean Valley.
In support of this announcement, Infrastructure NSW (INSW) completed a ‘strategic’ program business case. That business case recommended, as part of a portfolio of measures for the strategy, raising Warragamba Dam by around 14m for flood mitigation (the Project). WaterNSW is leading the delivery of the next stage of the Warragamba Dam wall raising Project for Infrastructure NSW (INSW), who are managing the delivery of the strategy for the NSW Government.
This next stage of the Project (termed Stage 3a), is the development of a final business case for the construction of raising Warragamba Dam by around 14m. The development of the final business case is being undertaken jointly with INSW. To assist in completing the final business case, WaterNSW will be undertaking further investigations, optimising the concept design, additional water modelling, programming, cost estimation, completing an environmental impact statement and obtain planning approvals. WaterNSW and INSW will jointly obtain all necessary legal and regulatory approval with the final business case being completed in mid-2019.
The Darling River and the Menindee Lakes Storages Scheme, located approximately 100km to the southeast of Broken Hill, provide the primary means of water supply drought security via the existing above ground Menindee pipeline.
Ongoing water supply security concerns and water shortages periodically affect Broken Hill. To secure the water supply requirements of Broken Hill and surrounding communities, the proposed solution has been adopted to source water from the Murray River near Wentworth and pumping via a 270 km pipeline to Broken Hill’s existing Mica Street Water Treatment facility and Stephens Creek reservoir inclusive of associated infrastructure. The intended completion for these works is late 2018.
