Trenchless upgrade for Bowral gas network

Gold-lining involves inserting modern, high-density nylon piping into existing gas mains – such as old cast iron mains and old high-density polyurethane gas mains.

“Rehabilitation of the Bowral network will minimise the likelihood of gas leaks or a loss of gas which sometimes happens when these old cast-iron pipes become rusted or the old HDPE gas mains start to crack,” said Jemena General Manager for Gas Peter Bowden.

The Bowral rehabilitation project is one of many that are part of Jemena’s $A810 million investment over a five-year period to upgrade and extend the Jemena Gas Network.

Since 1987, Jemena has rehabilitated almost 6,000 km of gas mains, which represents almost a quarter of the 25,000 km-long Jemena Gas Network in New South Wales. This network distributes natural gas to over 1.1 million homes and businesses throughout the state.
