Lockyer Valley & Somerset Water Security Scheme

Additional Information



Lockyer Valley and Somerset regions have been consistently working towards water security through advocacy and planning for a considerable period. As agriculture and associated industries are key economic drivers for our regions both local governments identify the importance of sustainable water security for agriculture in their respective strategies. Significant studies have been undertaken. Users have sought to improve the efficiency of water use. Sustainable and secure water supply is fundamental for our regions given our reliance on this resource. This project seeks to secure additional water for farming, business, industry and tourism.

Water from Lake Wivenhoe could be transferred to the Lockyer Valley through a new pipeline (shown beside) or reusing the existing Lake Wivenhoe to Cressbrook Dam pipeline in part (not shown). Lake Wivenhoe is the largest storage in South East Queensland and is replenished by rainfall so is sustainable.

Recycled water may be supplied to the Lockyer Valley in large volumes from the Western Corridor Recycled Water Scheme when the scheme is not required to meet urban demand. Recycled water could be supplied through a direct offtake from the existing scheme via a new storage at Lowood. Recycled water is sustainable in the long term based on existing wastewater collection and treatment technologies.

Distribution infrastructure includes the existing storages of Atkinsons Dam, Lake Clarendon, Lake Dyer/Bill Gunn Dam and additional storage infrastructure at Lowood and Gatton. The proposed trunk network totals approximately 48.3km, and the distribution pumping and pipelines from the three major storages is an estimated network of approximately 150km of reticulation mains.
