Thames Water is investing more than £20m to upgrade water infrastructure in Berkshire.

The investment will fund a series of projects across Woodley and surrounding areas, including an £8.4m improvement at Bowsey Hill Service Reservoir and an £11m upgrade at Sheeplands Water Treatment Works.

The investment will deliver upgraded water treatment and monitoring systems, new chemical dosing processes to improve drinking water quality and infrastructure improvements that help maintain supply during planned outages.

Thames Water said for customers this means “stronger compliance with Drinking Water Inspectorate standards, improved resilience for the area and a lower risk of water quality issues or service disruptions”.

The majority of the work will be delivered over the next five years as part of Thames Water’s Asset Management Period 8 (AMP8) investment programme, with some elements completed sooner and others extending over a longer-term period.

Paul Wetton, director of water programmes at Thames Water, said: “This investment is an important part of the biggest upgrade to our infrastructure in 150 years, helping us modernise our network, protect water supplies and deliver a more resilient service for customers.

“By upgrading treatment works, improving monitoring and investing in new processes, we are helping to maintain high standards of drinking water quality while supporting future demand and population growth.”
