Thousands Face Extended Boil Water Advisory Following Storm Damage

An advisory for thousands of residents to boil their tap water has been extended for an additional week, as repair work proceeds at a water treatment facility that experienced flooding during Storm Bert. Dŵr Cymru Welsh Water has issued an apology and enhanced its compensation offer to both affected customers and businesses. According to its chief executive, teams are operating “24/7” in an effort to expedite repairs to the drinking water storage tank located at the Tynywaun treatment works, situated above Treherbert in Rhondda Cynon Taf. He stated that nearly 100 staff members were engaged in managing the incident, staffing bottled water distribution points, and delivering supplies to vulnerable customers. A “boil water notice” was initially issued to approximately 12,000 households in Rhondda last Sunday, and this advisory has now been prolonged until Sunday, 8 December. This notice affects residents residing in Blaenrhondda, Blaencwm, Tynewydd, Treherbert, Treorchy, Cwmparc, Ton Pentre, Gelli, specific areas of Pentre, Tonypandy, and Ystrad. Additionally, fourteen schools, two hospitals, eight care homes, and 17 childminders are receiving alternative water provisions, supplied through tankers or bottled water deliveries. Victoria Vickery, from Only Crumbs sandwich shop in Treorchy, stated: “We can’t serve hot drinks at the moment and when we’re preparing food we’ve got to wash the veg and salad in boiled or bottled water.” She added: “It’s taking time and obviously it’s affecting us money-wise.” On the high street, shopper Janice Cook described the necessity of continually boiling water at home as “terrible”. She further commented: “You forget sometimes and then think ‘oh, I better not use that now’ – it’s hard work.” Ann Clarke remarked, “I won’t touch my tap,” but also noted that Welsh Water had been delivering bottled water to her residence because she is categorized as a vulnerable customer, which she found “marvellous”. Rhys Richards, a teacher, characterized the situation as “certainly inconvenient and less than ideal at this time of year with Christmas on the horizon”. He expressed that Welsh Water’s messaging and communication had been clear, adding, “but let’s hope they can sort it soon.” In a communication addressed to residents, Welsh Water chief executive Peter Perry stated that the weather gauge at Tynywaun recorded “the second highest rainfall in the UK last Saturday and Sunday”. “This resulted in a significant amount of flooding (at the treatment works) and surface water running from the hill onto the drinking water storage tank and impacting the tank.” Mr Perry indicated that the necessary repair to reseal the tank would typically require “over a month”, but staff were working “flat out” to complete it within two weeks. He further explained that continuous rainfall had impeded progress, as dry conditions are essential for laying protective membranes. “We understand the inconvenience this has caused for customers… and we’ll do all we can to bring that boil notice off as quickly as possible.” An additional £100 is now being provided to affected households, supplementing the £150 previously committed, while businesses will receive a total of £500. Concurrently, Rhondda Cynon Taf council is providing a £1,000 grant for impacted businesses and residents, and reported on Thursday that 192 applications had been submitted to date. The council reported that approximately 249 properties experienced internal flooding as a result of Storm Bert. An additional 140 residential and commercial properties in Caerphilly have also been flooded, as per the council’s information. In other areas, Powys council has confirmed that 16 properties sustained flood damage. Powys currently lacks a financial assistance program but is seeking aid from the Welsh government; individuals affected by flooding are eligible to apply for council tax relief. Welsh Water stated that it had dedicated months to preparing for winter demands, following a series of critical assessments by regulators concerning its overall performance in recent years. In October, Ofwat mandated the firm to pay a £24.1m penalty, and it was identified as one of only three water companies in Wales and England classified as “lagging”. The regulator for the water industry criticized its performance in areas such as addressing supply interruptions, conducting mains repairs, managing leakage, and handling pollution incidents. Furthermore, its environmental credentials have been consistently downgraded by Natural Resources Wales (NRW), declining from a four-star rating (industry leading) to two stars (requires improvement). Kit Wilson of Welsh Water commented that the current examination of the sector places “even more importance” on how the firm manages the upcoming colder, wetter months. He stated: “Winter is when we see the most impacts to our network, and that’s becoming even more prevalent as the impacts of climate change grow stronger and stronger.” When questioned about why customers should trust the firm’s preparations, Mr Wilson responded that it was “always disappointing when we as a company don’t meet the expectations of our customers or our regulators”. “However we have a really ambitious investment programme planned for the next five years, which will invest a huge amount of money – over £4bn – into our network.” He concluded: “We really think this will be a step change and start to change some of those perceptions.” At the company’s headquarters on the outskirts of Cardiff, Mr Wilson provided BBC Wales with a tour of its “gold room,” the central point for managing incidents impacting the water network. Team leaders representing various departments were seated around a table, with additional members participating remotely, and the surrounding walls and screens displayed numerous maps and diagrams. Mr Wilson stated that artificial intelligence (AI) technology was being utilized for the first time to help forecast potential issues, such as blockages or pollution, thereby enabling staff “to intervene before problems can escalate”. At Welsh Water’s Clydach depot, operational supervisor Lauren Johns mentioned that winter preparation efforts commenced in the summer, involving teams inspecting and maintaining tankers, generators, and other equipment, as well as accumulating bottled water. Characterizing winter as “a real challenge,” she affirmed that the company’s “absolute goal is to ensure that customers are kept on supply even if there’s an issue, and ideally, never find out that there was an issue in the first place”. Mr Perry indicated that Storm Bert served as an early assessment of the firm’s winter preparations. He noted: “We had an emergency planning exercise in the schedule for this week.” “But now that plan is in full swing and we’ll sustain that for as long as we need to.”
