Sewer mains in 45 Central Coast suburbs have been rehabilitated

Sewer line upgrades across 42 suburbs

Sewer mains in 45 Central Coast suburbs have been rehabilitated this financial year using an innovative technology that extends the life of the infrastructure by up to 50 years.

Almost half that number have been in the north, to ensure that infrastructure in the area is ready for the expected population growth.

Council Director, Water and Sewer, Jamie Loader, said that Council’s maintenance program has improved reliability, lowered the risk of environmental discharges and ensured the region is well positioned to cater for future population growth.

“We have an ongoing maintenance program for the extensive 2,649km sewer network across the whole Coast region and our focus is on rehabilitating damaged sewer pipelines or replacing end of design life equipment,” Loader said.

“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.”

Northern suburbs included in the maintenance program are Alison, Bateau Bay, Berkeley Vale, Blue Bay, Budgewoi, Buff Point, Gwandalan, Halekulani, Killarney Vale, Long Jetty, Norah Head, Ourimbah, San Remo, The Entrance, Tuggerah, Tumbi Umbi, Watanobbi, Wyong and Wyongah.

Council actively monitors and tests the effectiveness of the sewer mains network across the Coast and results indicate areas due for maintenance.
