Previous open days
We had a successful open day at Bray Keleher Water Treatment Works, near Maidenhead, on Saturday 26 April 2025.
Visitors had three tours to choose from throughout the day. They were able to step inside the control room at the water treatment works, learn how we use technology to find and fix leaks, and see how we filter, treat, and pump drinking water to your homes and businesses.
