Welsh Water’s pollution incidents shot up last year, despite the company spending hundreds of millions of pounds to “improve services”.

The company recorded 107 pollution incidents in 2023-24, up from 89 the year before.

Welsh Water has faced criticism in recent months over its performance on leaks and raw sewage spills.

Chairman Alastair Lyons said the company had “still more to do” but was making “good progress”.

Natural Resources Wales (NRW) reduced the company’s rating in June 2023, meaning it “requires improvement”.

Welsh Water did not state how many of the 107 pollution incidents were serious.
