Welsh Water has confirmed that persistent water supply problems in Penderyn were caused by electrical faults at the local pumping station, in a formal response to a community petition — but has stopped short of committing to a public meeting or a timetable for further action.
Residents and businesses in the village have reported repeated incidents of low water pressure, discoloured water and loss of supply since 2024, with a petition submitted calling for greater transparency, a public meeting with local representatives, a clear timetable for improvements, and compensation for those affected.
In a written response, [Name], Chief Customer Officer at Dŵr Cymru Welsh Water, apologised for the disruption and said the company’s investigations had found the problems were caused by “a combination of electrical faults impacting the pumping equipment serving the locality, alongside wider power outages which intermittently affected the operation of the pumping station.”
The company said it has since installed new pumps and upgraded electrical drivers at the site, which it says will “improve the resilience” of the supply and “reduce the likelihood of similar disruption occurring in the future.” Welsh Water maintains that water supplied to the area continues to meet all regulatory drinking water quality standards.
No commitment to public meeting
Residents had specifically requested a public meeting with Welsh Water and local representatives. In its response, the company stopped short of agreeing to this, instead asking that “your local representative contacts us directly with the proposed criteria, so that this can be reviewed and suitable representatives arranged as appropriate.”
No date has been given for when, or if, such a meeting will take place.
Compensation left to individual claims
On compensation, Welsh Water pointed to its existing Guaranteed Standards Scheme (GSS), the industry-wide scheme that provides for automatic or claimed payments where customers experience qualifying interruptions to supply. The company said any entitlement would be “assessed against the specific circumstances of each incident,” and encouraged affected customers to contact it directly to have their case reviewed — rather than confirming blanket compensation for the community as a whole.
Under GSS rules, households can typically claim for supply interruptions that are not resolved within set timeframes, and for water pressure that repeatedly falls below the minimum standard, though claims generally must be made within three months of an incident.
Background: a recurring problem
This is understood not to be a new issue for Penderyn. The petition behind the complaint noted that previous improvement works carried out by Welsh Water have not resolved the underlying problems, and residents have raised concerns that without a clear timetable or independent verification, there is little assurance that the newly installed equipment will prevent further disruption.

What happens next
Welsh Water says customers who believe they have been financially or otherwise affected should contact the company directly to have their individual circumstances reviewed. The company has pointed residents to its “How we handle your complaints and compliments” booklet for further detail on its complaints process.
Welsh Water contacted for comment
Welsh Water was approached for comment on this story on Friday 24 July, three days ahead of publication. In response, a Welsh Water press officer, who signed as “Gwydd,” replied to say “you have already used our response – I’m not sure what else I can add.”
Three specific questions not addressed in the company’s earlier written response to the resident’s petition were then put to Welsh Water: whether it would commit to a public meeting and, if so, when; whether there was a specific date by which the newly installed pumps and electrical upgrades would be reviewed for effectiveness; and whether affected households would be proactively assessed for compensation under the Guaranteed Standards Scheme, or would need to claim individually. A named, attributable response was also requested for publication.
Welsh Water’s press office did not answer these questions in writing. Instead, over the following two days, two further members of the press team — Gwydd again, followed by duty press officer Danielle over the weekend — asked to arrange a phone call rather than respond in writing, and did not provide a written statement by the agreed publication deadline of 12pm on Monday 27 July.
Following the deadline, Welsh Water’s press office said it was “difficult… to comment on an issue when you have had a response from the company already,” and asked for clarification of the source of that earlier response, while again declining to provide a written statement and requesting a phone call instead.
At the time of publication, despite being contacted repeatedly over more than three days and given advance sight of the specific questions this article raises, Welsh Water had not provided a written, attributable comment.
