Why does National Grid have to dig up the roads - isn't there a better alternative?
To operate a safe and efficient gas supply network it is necessary to continually invest in and improve our existing assets.
We have a continuing mains replacement programme, and Streetworks are an inevitable part of delivering such programmes.
Whenever possible we use new technology to help minimise disruption, such as inserting the new pipe inside the original main. These can help speed up the process and reduce the need for digging trenches.
