Sewer mains in 45 Central Coast suburbs have been rehabilitated in the past financial year to improve the performance and reliability of the networking by extending the infrastructure’s life by up to 50 years.
Central Coast Council Director Water and Sewer Jamie Loader said the maintenance program, using “innovative technologies”, has improved reliability, lowered the risk of environmental disruption and ensured the region is well positioned to cater for future population growth.
“We have an ongoing maintenance program for our extensive 2,649 km sewer network and our focus is on rehabilitating damaged sewer pipelines or replacing end-of-design-life equipment,” said Mr Loader.
“We’re using an innovative technique to rehabilitate damaged sewer pipelines with structural re-lining, rather than replacing the infrastructure, and we start by clearing the pipe and assessing the conditions of sewer lines via CCTV camera.
“If required, we insert a liner that reinforces the existing pipe structure, sealing any leaks and significantly reduces the risk of future damage – particularly from tree roots, the number one cause of sewer blocks and overflows.
“This technique also eliminates the need to excavate in most cases, which minimises disruption to the community and reduces repair costs.”
This investment in critical infrastructure will now ease the pressure on the network for the growing population and enhance the liveability for residents, Mayor Lisa Matthews said.
The Central Coast Council has actively monitored and tested the effectiveness of its sewer mains network across the region to indicate areas due for maintenance, which it will continue to do following this rehabilitation program.
