Water levels in ‘good position’ but Dwr Cymru sounds warning

Dwr Cymru Welsh Water has ramped up production at its water treatment works and urged people to think about their water consumption.

March 2025 was the fourth driest March in history in Wales, with rainfall 30% lower than levels in 2022, when parts of Wales last faced restrictions on water usage.

Now, Wales has had the hottest beginning of May on record.

Welsh Water has said reservoir water levels are currently just below what is expected for this time of year.

But while the not-for-profit organisation said water resources are in a “good position” across Wales, it has still sounded a warning.

Ian Christie, of Welsh Water, said: “With the low rainfall levels, we are working around the clock to make sure we do everything we can to get as much treated water into the system, and our teams are out and about fixing 700 leaks per week.

“Although reservoir levels are at a comfortable level currently, we’re asking customers for their help so that we can make sure the water reaches everyone.”

He continued: “It’s essential that we help preserve the supplies in our reservoirs and rivers after what has been a dry Spring.

“Our advice is simple for customers, use the water you need but avoid wasting it.”

Welsh Water said its 61 treatment works produced an additional seven million litres of water on some of the warmest days this week – the equivalent of filling around 35,000 bathtubs each day.
