Welsh Water has issued an urgent warning to residents in specific areas of south Wales regarding tap water safety. This advisory follows a recent issue identified at the Maerdy Water Treatment Works.
Details of the Boil Water Notice
The warning covers the Rhondda and the broader Rhondda Cynon Taf region. An issue with the chemical treatment process for drinking water was discovered during routine inspections on Friday morning. As a precaution, Welsh Water has temporarily halted the flow of water from this site into the distribution network.

Customer Communication and Support
Welsh Water is actively communicating with affected customers by sending text messages. For those who haven’t received notifications, a postcode checker is available to confirm whether they are in the impacted area. This lack of communication has raised concerns, as some residents reported consuming unboiled tap water before the alert.
In response, bottled water stations are being established to assist vulnerable customers registered on Welsh Water’s Priority Services Register. The organization aims to ensure access to safe drinking water while the issue is being resolved.
