Tillegra Dam
Tillegra Dam is an integral part of the State Government’s $342 million plan to secure the water future of the Lower Hunter and the Central Coast regions for at least the next 60 years. Subject to receiving the necessary approvals, the proposed 450 billion litre dam is to be built on cleared grazing land in the upper Williams Valley (north of Dungog) at an estimated cost of $300 million (2006 dollars).
In August 2007 Hunter Water published a paper entitled Why Tillegra Now? The paper has been written as a resource for stakeholders as well as the broader community. It outlines why Hunter Water needs to enlarge its existing water supply with a new water source, and demonstrates why Hunter Water believes Tillegra is the right decision for the Lower Hunter community.
The paper discusses the international, national and local water resource planning environment, the implications of climate change on reliable water yield for the area, future demand for water in the Lower Hunter, water efficiency initiatives (current and future) and options considered for source augmentation for the region.
