New figures show sewage was released into rivers, lakes and the sea around Wales for more than 800,000 hours last year.

The charity Surfers Against Sewage, which has analysed data from Wales' water companies, said there were more than 100,000 sewage discharges in 2025 - or one every five minutes.

The figures are down on the year before when sewage was discharged for more than 970,000 hours.

Natural Resources Wales (NRW) said it had strengthened its approach as regulators through increased monitoring and tighter guidance, and had overseen "significant programmes of environmental investment" by water companies.

Surfers Against Sewage said part of the reason for the drop was the dry weather seen during the summer last year, but underinvestment and a lack of enforcement remained an issue.

In its annual assessment, it said since 2019 it had received 992 reports of sickness in Wales caused by sewage, with 215 of those coming in 2025.

It said the impact of those sickness reports led to more than 2,200 days off work.

According to the charity, sewage was discharged into Wales' designated bathing waters for a total of 35,669 hours over the year.

At Llyn Padarn, Gwynedd, despite the lake's designated bathing water being classified as "excellent" for water quality, discharges lasted 1,614 hours.

Rules allow a limited discharge of sewage in periods of excess rain, but environmental groups remain concerned the levels pose a threat to wildlife and a health risk to swimmers.

chief executive of Surfers Against Sewage, said last year's figures equated to a discharge every five minutes, which he called a "shocking statistic".

He pointed to 90 places that authorities have said are good places to swim, but said they'd "been impacted by over 4,000 hours of sewage pollution".

"It's a really terrible picture that we're seeing of continued underinvestment and a lack of enforcement to ensure that this isn't happening," he added.

"People's lives and their health are being put at risk when they go to enjoy these amazing places."

Welsh Water said it would invest a record £2.5bn over the next four years, and understood the concerns about sewage discharge.

Hafren Dyfrdwy - which operates in mid and north-east Wales - said it was "working tirelessly" to reduce the average number of spills but "we know more needs to be done".

"Which is why we're investing £11m at our storm overflows to reduce spills to fewer than 20 a year by 2030," it added.

The Welsh government said it was "taking full control of water in Wales" and would "apply the polluter-pays principle, including prosecuting serious and persistent offenders".

"We take our responsibility to protect these waters seriously and recognise that we need to improve," it said.

"In line with Welsh government policy, we are prioritising the overflows causing the greatest environmental harm."

Waited for a call from hafren dyfrdwy (severn trent water) today. Thought I would get an explanation re-some poor customer service issues that have happenend recently,Tracy called 2.40 ish she had no answers to my Qs, just that you must pay this new increase after living in the house for more than 8 years with no explanation why! apart from( its the rain that comes off your drive ) I wanted to know why they have waited this long to tell me about the increase without ever raising the issue, Tracy seemed to think this was way beyond her remit and advised me to go back to billing!?!So why did she telephone me?!!!

We noticed the water coming out of our taps was brown ? so rung our water supplier , firstly they took a long time to answer, with nothing on the call telling you how many people in front of you there was which is poor for a large company at least then you know the call is getting through at some time and you can decide whether to hang on or ring back ?
the lady we spoke to was nice but new and did not know anything and had to ask her manager and then still it was very vague what they were going to do ? if somebody could email us later ? the only thing they wanted was us [the paying customer ] to test our water and they said it was fine even though nobody had checked it ?
you cannot choose your water company if you colud it would not be this lot for sure, very poor service

45 minutes wait for reply to report no mains water,patiently.waiting as per the recorded message.Hung up in frustration.Apalling response

Speaking strictly as a residential customer I cannot fault them at all.

They answer the phone promptly and have always dealt with my requirements efficiently and quickly.

Makes a refreshing change from some utility companies.

I would give a zero but cant! So on a public pavement outside ours under the manholes there are toilets blocked- baby wipes. Not the 1st time!! We ask a plumber to look and he calls metro rod to blast. They say shared drains and likely to be a neighbour - so now a massive bill. Hafren Dyfrdwy then says we should have called them 1st (even though they would not come immediately and at the first stage there is water flowing from upstairs to downstairs out of a toilet). So if you do not know what the problem is with your house flooding and call for immediate help - thats wrong. Apparently we should have called HD and waited (for upstairs to fall through to downstairs). So how exactly are we supposed to know that we should not call a plumber out to investigate? You wont pay as you were not our first call. Our first call was to a local plumber who came immediately which took 4 to 5 minutes - to save the house. So you wash your hands of this as we didnt call you first and wait patiently. Crap service. Literally.

Emily in Wrexham has been a massive help and cannot fault her one bit! We need more Emily’s in the world!!

Kevin and mick they are very helpful
Amazing job thank you

Water meter reader cannot read a water meter correctly. Wrote to customer service months ago asking for a re-read, so now left with a large bill. Terrible.

We were having persistent issues with a backed up drain, with no luck of finding the problem. Had Wayne & Josh come out and they managed to find the issue very quickly and resolve the issue while explaining what had happened.
