Around 400 customers in the villages of Upper Cumberworth and some parts of Denby Dale, near Wakefield, were affected by severe problems with their gas pressure early on Monday October 27.
Northern Gas Networks and its operating partner United Utilities instigated a full emergency response to the situation. This involved visiting all affected homes to carry out essential safety checks. As a precautionary measure, 143 customers had their gas supplies temporarily switched off.
The problem was caused by water which had entered the gas mains system. The prompt action of engineers prevented the need for further losses of supply and 6,000 litres of water was safely siphoned from the local mains network late yesterday afternoon to restore normal operating pressures.
Emergency engineers worked late into the night re-connecting customers and visiting all affected homes and businesses. Where access was not possible, information has been left. However engineers are on site today.
Northern Gas Networks would like to apologise to customers in Upper Cumberworth and Denby Dale for the unexpected pressure problems, particularly to those who were without gas. Further investigations are continuing into the cause of the problem to prevent it happening again.
