Dwr Cymru Welsh Water customers in Pembrokeshire can be assured of top quality drinking water for the future as investment in the area hits £2.5 million. Two major improvement schemes in the county are due to start, and will bring direct benefit to customers across the county. The first scheme, commencing on Monday, April 25, will involve renewing 10km of water mains as a first phase. This work will begin in Johnston village, and will progress through Sentry Cross and Waterston to the outskirts of Llanstadwell. The second scheme, commencing in the Llanteg, Ludchurch, Stepaside and Amroth areas, will begin on Monday, May 9, and will involve the replacement of 23km of water mains in the area. The combined works, costing £2.5 million, will continue to deliver a high standard drinking water from Dwr Cymru Welsh Water's treatment works direct to customers' taps. In preparation for the schemes, Dwr Cymru Welsh Water has liaised with Pembrokeshire County Council. As part of the traffic management plan it will be necessary to use temporary traffic lights and some road closures will be required. In these cases, alternative diversionary routes will be in place and will be clearly signposted in advance, giving local residents the opportunity to make alternative plans. Dwr Cymru Welsh Water asset manager, Peter Childs, said: "The essential water improvement work taking place in Pembrokeshire shows our commitment to supplying top quality, reliable water direct to our customers. "We apologise for any inconvenience that our customers may experience when the work takes place." He continued: "Before any work starts, all customers whose water supply will be directly affected will receive an information pack explaining how the work will impact on them. We ask people to read this carefully and keep it in a safe place to refer to whilst work is ongoing." The schemes will be delivered by Laing Utilities, working with United Utilities, ChandlerKBS and other partners carrying out the water mains refurbishments programme, on behalf of Dwr Cymru Welsh Water.
