Welsh Water’s investment and performance: April to September 2025
We recently announced our half year results which outlined an investment of £650m in 2025/26, the first year of our 5 year investment plan. Between 2025 and 2030 we will invest a total of over £4bn, with £2.5bn of that sum invested in the environment.
The money will deliver improvements for customers, communities, and the environment, such as the recently opened £13 million wetland storm overflow at Pont-y-felin in Torfaen – the first of its kind in the UK. By harnessing the natural filtering power of wetlands, the site is already reducing the company’s impact on local rivers and setting a model for future sustainable investment.
We have also launched consultations on the largest infrastructure project in the company’s history – the Cwm Taf Water Supply Strategy. The plans will modernise the drinking water network across South Wales, replacing century-old treatment facilities and increasing clean water storage capacity.
Between April and September 2025, our investment led to progress on reducing incidents of internal and external flooding, improving river water quality and overall pollution incidents.
Environmental Performance Assessment remains at two stars, with improvements noted in four of the seven elements that measures performance in the last year, and the total number of pollution incidents is the second lowest in the industry.
Careful management of water supplies during the dry periods over spring and summer meant there was no need for temporary restrictions or ‘hosepipe bans’ across our operating area – unlike several parts of England.
The investment we have outlined will improve our service to customers and the environment through the acceleration of investment and a focus on performance results, across our operating area.
