Improving the wastewater system near Barney Street
We’ve been working to improve the wastewater system off Barney Street, Kiama, to help reduce wastewater overflows on private properties during wet weather events.
When we started in February 2022, we honestly thought our project would be finished by now and the new Emergency Relief Structure (ERS) that we’ve been building would be operational.
Unfortunately this project has not gone to plan and we’ve had a number of setbacks. The latest being deficiencies found in the Epoxy coating applied to the new ERS. Repairs will need to be made to this coating to ensure it functions as intended into the future.
The remaining work on site includes:
- remediation of the Epoxy coating inside the ERS
- test and commission the new ERS
- installation of safety screens beneath the concrete lids.
We’ll be starting to do these activities from Monday 12 February and will try to finish as soon as we can. Due to the nature of the remaining work, it will happen intermittently, and residents will notice some temporary ATF fencing around the ERS from time to time. We’ll aim to leave this in place for as short a time as possible.
Access to the beach, shared pathways, car park, picnic tables and showers will not be affected.
We sincerely appreciate the cooperation from the community that we’ve continued to receive and we apologise that this project has taken longer than originally expected.
Epoxy is a protective paint used on concrete surfaces in wastewater systems for water proofing and to protection against corrosion.
