Work is currently under way on the construction of a pressure sewerage system to service existing properties in the South Nambucca area along the Pacific Highway from Teagues Creek to Florence Wilmont Drive.
A pressure sewerage system comprises network of pump stations on individual properties connected to a common transfer pipe within the road reserve that discharges into Council’s existing sewerage system near Teagues Creek. The pipework is small diameter poly pipe and each pump station is capable of pumping flows around 1 l/s at over the full length of the transfer pipe.
Council invited Expressions of Interest from experienced contractors for the design and construction of the works based on an earlier concept design that was documented for Council. Following a select tender process a contract was awarded to Pressure Sewer Services Australia Pty Ltd in August 2016.
Works began on site in early February 2017 and the contractor is making good progress to date. Most of the pipework has been installed using directional drilling with minimal disturbance to property owners. All residential pump stations have also been installed however plumbing and electrical works for pump station controls are yet to be completed.
Works on the contract are expected to be finalised prior to the end of May 2017.
The objective of the new works is to replace existing on site wastewater systems to reduce the risk of any environmental impact these systems may have as a result of being located in close proximity to the Nambucca River. The provision of the sewerage system will also provide an opportunity for the development of vacant land in this area.
The new sewerage system will be operated and maintained by Council.
The assistance of the Federal Government in providing a grant of $241,340 through their National Stronger Regions Program is acknowledged.

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.
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.
