 Friday 2 March 2018

Due to extreme weather conditions and concerns around the health and safety of the teams on site, and members of the public. We have decided to postpone works to connect the water mains until Monday. Due to the postponing of these works, work to fully restore the road will be delayed further, unfortunately we can not confirm a date the road will be opened at this stage. We will provide a further update on Monday 5th March.

We are sorry for any inconvenience caused and would like to thank our customers for their patience during this time.

 

Further updates to follow Monday 5 March


Wednesday 28th February 2018

Tests to the new water mains have now been completed and work to connect the new mains will begin on Thursday 1st March as scheduled. 

However, due to the adverse weather conditions, work to restore the road will be delayed.

Friday 23 February 2018

Our team are now in the process of placing the welded pipework into the large trench previously shown in the photos below. We anticipate this will be fully laid before the weekend ends. Once this work has been carried out we will secure our final fittings on the ends of the pipework and plan to carry out our final connection to the surrounding pipework on Wednesday 28th February. 

Providing there and no complications, this will give us time to fully pressure test and chlorinate the water main, and begin the process of backfilling and reinstating the considerable excavation on site.

We anticipate that we will be in a strong position to re-open the slip-road to traffic on the 5th of March as previously communicated. We would like to thank all our customers and road users for their understanding and patience during this tricky repair, and once again apologise for the disruption this incident has caused road users.

Thursday 22 February 2018

Update 19:40

Yesterday our repair teams completed a connection at one end of Rowley Lane and have continued the welding of 100 meters worth of large 560mm thick pipework today.

We will be working overnight on a major connection of our new pipework between 21:00 - 06:00. On completion of the mains replacment we will begin required water sampling and testing to ensure our high water quality standards for new pipework. An extensive reinstatment and tidy up will then be required. 

We are currently on target to have all works completed by Monday 5 March. We appreciate the continued patience of road users, and apologise for the delays this has caused customers who travel through this area.

Wednesday 21 February 2018

Update 19:05

Our repair teams have completed a conection at one end of Rowley Lane and have nearly completed the welding of 100 meters worth of large 560mm thick pipework. We anticipate we will have this completed and the second connection at the far end of the water main completed by tomorow night.  Following this water sampling and testing will take place. Due to the understandibly high water quality standards this sampling will take aproximatly 5 days before we are able to return the water main to general service. An extensive reinstatment and tidy up will then be required. 

We are currently on target to have all works completed by Monday 5th March.

We appreciate the continued patience of road users, and apologise for the delays this has caused customers who travel through this area.

Tuesday 20th February 2018

Update 18:30

Our teams remain on site and work is well underway. We have successfully tunnelled a trench from Rowley lane to the A1 connection point and will begin the laying of our new 560mm wide pipework. During this time we will also be replacing two connection points, one at either end of the 100meters of pipework that is being laid. We have deployed a pipe welding robot to speed up the process of laying this pipework and additional fittings are en-route to the location to ensure we are prepared for any further complications. 

We appreciate this complex repair is causing traffic delays, and we would like to thank all of our customers for their continued patience.

Monday 19th February 2018

Update 16:45

Our teams are continuing to work to excavate and prepare the site to lay over 100 metres of new mains pipes following the bursts along Rowley Lane, just off the A1 in Borehamwood.

The new mains will improve the resilience of the water network in the area and minimalise unplanned interruptions in the future. 

We plan to install the new mains on Thursday and begin our testing process soon after. This process can take up to five days as we must ensure the new pipe meets our high water quality standards before we can put it into service.

After the testing process is complete, we will then work on restoring the area and reopening the slip road. Due to the extensive excavation required to lay the new main, restoration may take some time and we hope to complete this by 05/03/2018. 

We realise that this work is causing delays for commuters and we are very sorry for the distrubtion that this has caused. Rest assured, we are working hard to complete the installation of the new mains as quickly and safely as possible and we would like to thank our customers for their patience during this time.

Friday 16th February 2018

Update 09:15

 

We are sorry for any inconvenience caused by the recent major bursts on one of our large diameter water mains on Rowley Lane, just off the A1 in Borehamwood.

Our teams worked hard to excavate the water main, which was much deeper than usual at over seven meters below ground. This required an extensive excavation which added to the complexity of the repairs.

On further investigation, our technicians have found the water main to be in worse condition than expected. As a result we have taken the decision to completely replace a large section of the water main in this area. This will improve the resilience of the water network in this area and minimise unplanned interruptions in the future.

We realise that this work is causing delays for commuters and we are very sorry for the disruption that has been caused to date. As we are now replacing the water main, we will now need to extend the road closure on the slip road to the A1 until this is complete to ensure the safety of our technicians and commuters.

Rest assured, we are working closely with the local authorities to keep disruption to a minimum and working hard to complete the repairs as quickly and safely as possible.

We would like to thank our customers and commuters for their patience during this time.

This message will be updated as soon as an update becomes available.

 


 

Wednesday 14th February 2018

Update 13:30

 

Following the repair and re-charge of the water main on Rowley Lane, we have experienced another burst further down the pipe work in a grass verge closer to the A1.

Our repair team are on site and have managed to isolate the main which has since stopped the flooding onto the lanes on the A1.  As a result of this follow on burst we will be required to excavate further along the pipework.

During this work the slip road will have to remain closed to ensure the safety of commuters and our technicians working there.

We're very sorry for the disruption that this has caused and we will update customers with a realistic timescale for Rowley Lane slip road to be re-opened as soon as possible.

We would recommend that road users plan an alternative route on their journeys if possible, as there is likely to be continued congestion along this part of the A1.

We would like to thank our customers and the commuters for their patience whilst these repair are carried out.


 

Tuesday 13th February 2018

Update 16:45

 

We are sorry for any inconvenience caused by a burst along Rowley Lane, which has led to a road closure on the slip road off the A1 exit for Borehamwood. 

Our technicians have successfully charged the water main back up, however due to the impact of this incident we will be flushing the main a substantial amount over night in preparation for samples to be taken tomorrow.

As the burst has caused a large amount of damage to the road surface and a nearby drain network which will require repair by a 3rd party.

We are aiming to complete the repairs, restore the road surface and have the slip road re-opened by the end of this week.

During this time, the slip road will remain closed to ensure the safety of commuters and our technicians working on this complicated repair.

This is likely to cause traffic delays in the area and we would request commuters to find an alternative route during this time.

We would like to thank our customers and commuters for their patience whilst these repairs are carried out.

 


 

Monday 12th February 2018

Update 15:30

 

We are sorry for any inconvenience caused by a burst along Rowley Lane, which has led to a road closure on the slip road off the A1 exit for Borehamwood. 

Our technicians have now fully excavated the damage area of the main. We have obtained replacement sections to begin carrying out repairs on this main, however we are still awaiting additional sections of the main. 

With this in mind, we are still anticipating that works will likely be completed later this week. We will provide a further update tomorrow.

During this time, the slip road will remain closed to ensure the saftey of commuters and our technicians working on this complicated repair.

This is likely to cause traffic delays in the area and we would request that commuters find an alternative route during this time.

We would like to thank our customers and commuters for their patiences whilst these repairs are carried out.


 

Friday 9 February 2018

Update 14:00

 

We are sorry for any inconvenience caused by a burst along Rowley Lane, which has led to a road closure on the slip road off the A1 exit for Borehamwood.

Our technicians are working hard to fully excavate the area so that repairs can begin. However, the pipework is over 6 meters deep and the burst is located on a 6 meter long section of the main.

A wide section of this area needs to be excavated so we can fully expose the pipework. Due to its extreme depth, we estimate that we will not be able to fully expose the damaged main until Sunday evening.

The burst also caused a large amount of damage to the road surface and a nearby drain network which will require repair by a 3rd party.

We are aiming to complete the repairs, restore the road surface and have the slip road re-opened by the end of next week.

During this time, the slip road will remain closed to ensure the safety of commuters and our technicians working on this complicated repair.

This is likely to cause traffic delays in the area and we would request commuters to find an alternative route during this time.

We would like to thank our customers and commuters for their patience whilst these repairs are carried out.

Thursday 8 February 2018

Update 16:20

 

All customers should have a fully restored water supply.

Repairs are continuing to the burst water main along Rowley Lane, which has led to a road closure on the slip road off the A1 exit for Borehamwood. This is a complex repair as the pipework is over 6 metres deep underground and excavations are still in progress to fully expose the main.

The road closures are in place to ensure the safety of our technicians and commuters in the area and we would like to thank our customers and motorists for their patience whilst these repairs are carried out. These are likely to continue over the new few days into the weekend.

We apologise for the inconvenience and will provide an update as soon as one becomes available.

The pictures below were taken from the repair site:


 

Wednesday 7th February

Update 12:00

 

Although all customers have now seen full restoration of their water supplies,where it has been necessary to excavate the area there remains a significant impact to road users passing through the area. Our team will continue repairs on the damage pipework, and we would strongly advise road users to plan an alternitive route where possible.

There is a road closure in place along the sliplane exit for Borehamwood which will impact traffic levels along the A1 heavily.

We will continue to work with the local Highways Authority to return the road surface area to normal and ensure that the road is safe for all vehicle traffic. This will mean that we have to maintain the site and any necessary traffic management until this works are complete.

*Photos Below*

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

 


 

Update 13:00

 

We have successfully diverted water to the surrounding area and aniticipate full restoration of your water supply within the next hour.

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

 


 

If you are in the above area and are experiencing problems with your water supply, we currently have a burst water main on Rowley Lane which may be affecting you. Our repair team are on site and work to fix the damaged water main is now underway. We will provide an update and estimate on when this work should be completed as soon as one becomes available.

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.
