Shoalhaven Water is commencing an investigation to upgrade the existing Sussex Inlet Effluent Exfiltration System located at Cudmirrah Beach.
The exfiltration system discharges high quality, treated effluent from the Sussex Inlet Treatment Plant into the sand dunes. The exfiltration system was installed in 1990 and has recently experienced blockages preventing optimal discharge. In order to alleviate the problems associated with the current system, Shoalhaven Water intends to undertake an investigation of the existing pipework and the surrounding structures with a view to replacement if and where required.
The works will be undertaken in stages with approximately 2,500m3 of sand being excavated per pipework section. Stockpiled material will be placed outside the excavation area but within the extent of works and then replaced upon the completion of works. Access to the work site will require some localised track widening and this will include some vegetation clearing. In addition, some reshaping of sand at the base of the track may be required to allow vehicles access.
Shoalhaven Water will be fencing the work area for public safety during this time. It is intended to commence the project in early July, and works are expected to be completed within 3 months.
An investigation is also being conducted on a collapsed sewer reticulation main in Lyons Road Sussex Inlet. Shoalhaven Water is working with pipe relining contractors to amend the problem and while the system continues to function the damaged section of the pipe requires the area to be fenced off for the next few weeks or until the rehabilitation works are complete.
