As we head into a dry and hot summer, learn how to keep you and your family safe
A review of the existing South Nowra Surcharge Main (SNSM) network has identified a need for the system to be significantly upgraded to address future growth and system pressure constraints.
By upgrading the system, the SNSM will be able to meet its operational needs and future demands. The upgrade will provide increased wet weather storage, improved pumping efficiencies and a reduction in sewerage retention times which will reduce the amount of odour being produced by the current system.
A Review of Environmental Factors (REF) report has been prepared for this project and publicly exhibited as part of the South Nowra Surcharge Main Upgrade project.
