Dŵr Cymru Welsh Water is introducing a Temporary Use Ban (also known as a ‘hosepipe ban’) across mid and south Ceredigion, together with parts of north Pembrokeshire and north Carmarthenshire, following a prolonged period of exceptionally high demand for drinking water. The area’s water supply is part of a single water supply zone served by two water treatment works.
The company is today issuing a public notice confirming that temporary restrictions will come into force from 10:00 on Sunday, 19th July to help protect essential water supplies after demand in the affected area remained significantly above normal throughout the recent spell of hot, dry weather, impacting on storage of treated water in the local network.
The company has experienced several weeks of sustained demand at unprecedented levels, with around one billion litres of drinking water being put into supply every day during the past week – around 20% more than would normally be expected at this time of year.
The affected area covers around 33,000 properties, stretching from Llanon, Llangwyryfon and Cwm Ystwyth in Ceredigion, across to Crymych, Llanfyrnach and Nevern in north Pembrokeshire, and into parts of north Carmarthenshire, including Farmers, Pencader and Hermon.
Unlike the short-lived peaks normally experienced during warm weather, demand has remained exceptionally high throughout the day and into the evening for several weeks. This sustained demand has placed unprecedented pressure on the local water supply network. Increased numbers of holiday makers and visitors to the area as the summer holiday season begins are expected to add further pressure to the local network.
While water resources and reservoir levels remain healthy, the challenge is producing, treating, storing and moving enough drinking water through the network quickly enough to meet this exceptional level of demand.
To maintain supplies, Welsh Water has already taken extensive action. Water treatment works are operating at maximum capacity, additional water is being moved around the network wherever possible, local service reservoirs (underground storage tanks) are being kept as full as possible, hundreds of frontline colleagues have been working around the clock repairing leaks and maintaining supplies, and the company’s entire tanker fleet has been deployed to support areas experiencing pressure.
Despite these measures, demand has continued to exceed what can be sustainably treated and supplied during the busiest periods of the day. As a result, local service reservoirs have been depleting faster than they can be replenished, increasing the risk of customers experiencing low water pressure or interruptions to supply.
The Temporary Use Ban is a short-term emergency measure designed to reduce non-essential water use, protect local storage levels and help ensure reliable water supplies continue for homes, businesses and essential services. It applies only to the affected area and will be lifted as soon as weather conditions improve, and local storage returns to sustainable levels.
Kit Wilson, Welsh Water’s Chief Customer Officer, said: “This has not been an easy decision, and we fully appreciate that these temporary restrictions will disappoint some customers, particularly during a period of warm weather. However, after several weeks of unprecedented demand, they have become necessary to help protect essential water supplies.
“Our teams have been working around the clock by increasing production, moving water around our network, deploying our tanker fleet and repairing leaks as quickly as possible. Every available operational measure has already been taken to maintain supplies.
“Over the past week we have been putting around one billion litres of drinking water into supply every day – around 20% more than we would normally expect at this time of year. Our reservoirs remain in a healthy position, but the challenge is producing, treating and moving enough drinking water through the network quickly enough to meet this exceptional and sustained level of demand.
“These restrictions are a temporary emergency measure and will remain in place only for as long as they are needed. We would like to thank our customers for their understanding and support. By reducing non-essential water use, everyone can help protect supplies and reduce the risk of further disruption.”
Under the Temporary Use Ban, customers must not use a hosepipe to:
- water a garden using a hosepipe
