Water Supply Problems - Potters Bar - EN6 - Saturday 20th July 2019

Update 19:00

We have successfully repaired the burst water main and anticipate full restoration of your water supply.

Should you experience any discoloured or aerated water which is not uncommon following a mains interruption, we recommend that you leave a mains fed tap running for approximately 5-10 minutes. Discolouration of the water is caused by small particles of iron which are within the mains and disturbed during interruptions.

Cloudy water is caused by air that becomes trapped in the mains, neither of these are harmful to your health. To see more about how to clear discoloured or aerated water why not watch our short video guide here

Where it has been necessary to excavate the area we will continue to work with the local Highways Authority to return the road surface area to normal and ensure that the road or footway is safe for all vehicle and pedestrian traffic. This may mean that we have to maintain the site and any necessary traffic management until this is the case.

We are sorry for the inconvenience caused by this incident and would like to thank our customers for their patience today.
