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.
