We would like to thank you for the patience shown during this tricky repair, and we are sorry for any inconvinience this has caused you.

This message will be removed Monday 12th after 08:00

Update 17:50

The repair on the main here was completed at 03:00 this morning. The main has since been flushed, sampled and returned to service.

The traffic management in place from our team was removed last night when the repair was completed. We currently have all lanes open along the A1 following the works. We are working on a two lane closure tomorrow morning from 09:30am, this will be required for plant and equipment to be removed from site and for the road restoration to take place.

We are planning to have completed our works and have all road lanes open for late afternoon tomorrow.

The pictures below were taken from the repair site.


Update 9:35

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.

Update 19:25

Our repair team are on site and work to fix the damaged water main is now underway.

We have isolated the damaged section of the water main, we anticipate all customers should have water during this repair. Our repair team will continue work throughout the evening.

The A1 now has 2 lanes open- 1 lane will remain closed for the duration of these works.

We will provide an update and estimate on when this work should be completed as soon as one becomes available.

We are sorry for the disruption to your supply and thank you for your patience.

We will update this message again after 08:00 on 8th February 2018

 Update 14:40 

In order to excavate the damaged water main, specialist equipment will be required, this work will take up a significant amount of space and in order to carry out works safely we will need to close two lanes (Southbound) from Trotters Bottom sliproad down to Stirling Corner roundabout. The team believe once they are set up on site there may be a possiblity that the lane closures can be reduced in size but this will need to be assessed once digging has commenced. 

We are sorry for the inconvience this has caused road users, and further updates will be provided when avalable. 

Update 13:30

If you are in the above area and are experiencing problems with your water supply we currently have a burst water main alongside the A1 near Galley Lane which may be affecting you.

Our technician has assessed the burst; a repair team have been called and are on their way to carry out the necessary work in order to restore supplies to normal.

During this repair there will be a full lane closure (Southbound) in place from the Trotters Bottom sliproad down to the Stirling Corner roundabout. This traffic managment will cause considerable delays, and we would strongly encourage road users to plan an alterntive route where possible.

We are sorry for the inconvenience caused.

We will update this message again after 17:00

If you are in the above area and are experiencing problems with your water supply, we currently have a burst water main on the Barnet By-Pass which may be affecting you. Our technician is on site and a further update will be provided as soon as possible.

During this time we ask you not to use any electrical appliances that require a water supply, for example washing machines or dishwashers and to conserve water from storage tanks during the time your water supply is interrupted.

If you do still have a supply, we would advise you to store some water for drinking, in case your water has to be switched off for a repair to be completed.

We are sorry for the inconvenience caused and aim to restore your supply to normal as soon as possible.
