An Environmental Impact Statement (EIS) was prepared on behalf of Nambucca Shire Council for the proposed Bowraville Off River Water Storage in the Nambucca Valley. The total $54m project cost will provide a dam with a surface area of about 60 hectares and a capacity of approximately 4,500ML as well as new bores, transfer pipeline, collection tank and associated infrastructure.
The purpose of the dam is to secure the water supply for the existing and future population of the Nambucca Valley during periods of drought. The stored water will be fed directly into the town supply system during periods of low river flows.
The EIS was on pubic exhibition from Thursday 22 October 2009 and the public were encouraged to provide written submissions by the 15 January 2010.
A hard copy of the documents can be viewed at Council's Administration Centre, 44 Princess Street Macksville. Enquiries to Richard Spain, Manager Water and Sewerage on (02) 6568 0234.
The Nambucca Shire water supply is a single source supply drawn from bores sunk into alluvial deposits adjacent to the Nambucca River upstream of the town of Bowraville. Studies have confirmed that the aquifer has limited storage capacity and cannot be expected to meet current and future water supply demands during periods of drought. During the drought of 2002 two of the eight bores began to run dry and it was estimated that there was between 30 to 60 days supply of water available when the drought broke.
Council engaged the NSW Public Works (NSW Water Solutions) to prepare a concept design for an upgrade of the works along with a REF (Review of Environmental Factors) to investigate the likely social and environmental impacts of the proposal.
