The works involve inserting modern, high-density nylon piping into existing cast iron and high-density polyurethane (HDPE) gas mains.
This process, which derives its name from the yellow colour of the new piping, reduces the need to dig trenches in the street and will minimise safety and environmental risks.
“Rehabilitation of the Stockton 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 of Gas Peter Bowden.
The Stockton project is part of Jemena’s $A810 million investment over a five year period to upgrade and extend the Jemena Gas Network.
The Network distributes natural gas to over 1.1 million homes and businesses throughout New South Wales.
