My water supply

On average, we supply 83 million litres of water to over 138,000 homes and 8,000 business customers.

Our treatment processes ensure that our water is clean and pleasant to drink.

Each year, we carry out thousands of tests on samples we have taken from treatment works, service reservoirs and homes across the region.

Water quality reports

The samples are analysed in a UKAS-accredited laboratory, to ensure they comply with drinking water safety standards.
