Sewage Pumping Stations - Emergency Storage Structures
Shoalhaven Water operate and maintain approximately 240 major sewage pumping stations (SPS) throughout its 13 sewerage schemes. On occasions, mechanical failure and power outages at the SPS sites can lead to unplanned discharge of raw sewage into the environment. These unplanned overflows have potential to adversely impact the surrounding environment, including private properties and waterways.
In order to reduce the risks associated with unplanned discharges, Shoalhaven Water has identified a number of high risk sites and propose to construct emergency storage capacity to act as buffer storages. These storages will provide additional time for staff to respond to emergency situations, thus reducing the risk of overflows.
The emergency overflow storage structures will be constructed at eleven (11) high risk SPS sites located at Berry, Culburra, Huskisson, St Georges Basin and Sussex Inlet. Construction commenced late 2020, with the various sites packaged and construction over a staged construction period, anticipated to conclude early 2022.
Prior to the construction of the SPS Emergency Overflow Storage Structures, Council undertook the following key environmental investigations:
- Review of Environmental Factors (REF) prepared by Cowman Stoddard Pty Ltd December 2015.
- Revised Review of Environmental Factors prepared by EMAP Consulting Pty Ltd 12 May 2020.
Project Progress - March 2022
All storage structures are now operational and the remaining minor works have been completed.
