WORK by the national grid has started to dismantle an unused gas holder.

The gas holder on Navigation Road, Pocket Nook is to be cleared as part of National Grid’s ongoing nationwide programme. Gas holders are no longer required due to investments made to improve the national network, meaning gas can be stored in the pipe system underground.

Work on clearing the navigation Road gas holder is expected to be completed by the autumn.

The Coleman Group, specialist contractors appointed by National Grid, will first remove and treat any water from the gas holder, before removing the sludge and any other debris from inside. The holder will then be dismantled.

When removing the sludge, an unpleasant smell, similar to diesel, is sometimes noticed. This smell is not harmful to people who live in the surrounding community or the environment.

National Grid say they will do everything they can to make sure it does not become an issue, including using odour suppressants.

The site will remain securely fenced at all times with full CCTV coverage.

The work will be strictly controlled to minimise any potential disturbance for people who live and work close by.

Hannah White, land regeneration manager for National Grid, said: “We will remove the gas holder as safely, quickly and efficiently as possible to minimise the impact on the local community and the environment.

“We have written to people who live and work in the local area to explain what we will be doing. If anyone has any questions about the project they can contact our community relations team on 0800 8199 071.”

National Grid’s gas safety guidance remains unchanged by the work.

If anyone thinks they can smell gas they should contact the freephone gas emergency number 0800 111 999.

All reports will be investigated by gas engineers to check if there is a gas escape.
