The Company Today

Bristol Water has supplied drinking water for over 167 years, always striving to provide high quality services and value for money.

We serve a population of 1.1 million people and all the associated businesses in an area of 2,400 square kilometres (1,000 square miles) centred on Bristol. Our area of supply ranges from Thornbury and Tetbury in the north to Street and Glastonbury in the south, from Weston-super-Mare in the west to Frome in the east. We provide a bulk supply of water to Bath. Wessex Water provide sewerage services in much of our area.

We own three major reservoirs (Chew, Blagdon and Cheddar) and a number of boreholes as sources of raw water. But nearly half the water used in our area comes from rivers outside our area of supply including the River Severn.

We have a range of treatment works from the simple to the highly complex. These feed water into a network of pumping stations, storage reservoirs and mains so that we can deliver high quality water to customers’ properties as they want to use it.

On average each person uses over a tonne (1,000 litres) of water each week.
