Shire reaps benefits of trenchless

The council said the project will use Trenchless Technology to reline its ageing clay sewer pipes, in order to minimise disruption to residents and the environment.

The council will reline 4 km of sewer mains in twelve suburbs across the shire. Each location has a history of sewer blockages.

Instead of entering people’s backyards to excavate and replace the pipes, council will be using a technology that relines the existing pipes with a new PVC pipe, the council said.

Wyong Shire Council Asset Management Engineer Luke Drury said “Completing trenchless sewer rehabilitation on this scale is relatively new to council but it has many benefits over other traditional methods.

“There is less noise, traffic disruptions and restoration work required. It extends the life of the pipes for at least another 50 years and is more cost effective.

“About 2 km of pipes have been relined so far. As this technology is less intrusive we are coming in under budget and we may add more relining sites to the list,” Mr Drury said.
