Welsh Water to invest £1.1 million to upgrade water main in Holyhead


Welsh Water is set to invest £1.1 million to upgrade the water network in Holyhead which will ensure customers continue to receive a first class, reliable supply of tap water for decades to come.

Work to replace nearly 4km of water main will start on the 9th of May on Porthdafarch Road and will carry on all the way to Cwm reservoir. As part of the scheme, a section of the water main will also be replaced on Plas Road near the allotments.

The majority of the work, which will take around 20 weeks to be completed, will mainly be carried out in fields.

Some work will be required in the highway on Plas Road for around two weeks but to minimise disruption and to protect the safety of local residents and motorists, a traffic management system will be in place.

Jim Grundy, North West Distribution Manager for Welsh Water said: “We have had some bursts in the past on the water main in the area which on occasions has unfortunately affected the nearby allotments. As a result we are investing over £1 million in the main which will improve the reliability of the network and ensure customers continue to receive a high quality supply of water.

“The location of the main is quite challenging and will mean that we will use three different techniques to replace it. Using these techniques will not only make sure that disruption will be kept to a minimum but also allow us to work in very hard and rocky ground near the reservoir on Holyhead mountain.”

One of these techniques includes slip lining, where the new main is inserted into the old one. This technique will be used on Plas Road near homes and where the allotments are as it’s quieter and quicker and will keep disruption to residents to an absolute minimum. It will also mean that we do not need to dig a trench the allotments.

The work at Holyhead will be carried out by our contractors Morrison Utility.

Linda Mulligan, Chair of the Plas Road Allotments said: “The pipe at Plas Road has burst a few times lately and has affected a number of gardens at the allotments. It’s great to see that Welsh Water are investing and renewing the main to make sure that the risk of this happening again is kept to a minimum. It will also mean that our tenants can start to plant their flowers and vegetables ready for the summer.”

Local Councillor, Trefor Lloyd Hughes said; “I’m pleased to see that Welsh Water undertaking this work in Holyhead. Following the last burst near the allotments they assured local residents they would carry out improvements and it’s great to see this happening and putting customers first.”

While the work is being carried out there shouldn’t be any interruption to customers’ drinking water supply. Should any customer need to have their water turned off for a short period of time while they are connected to the new supply, Welsh Water will contact them to let them know.
