Water quality

Excellent water quality is fundamental to providing the level of service our customers expect from us. Our aim is always to supply water that is not just safe to drink but is good to drink. We achieve this using advanced treatment processes and a team of highly trained staff.

Proof of this lies in our water quality results, with over 99.9% of the 120,000 drinking water tests carried out each year being compliant with UK and EU drinking water standards.

Continued investment in new treatment processes, renovation of water mains and partnerships with catchment stakeholders (click here to go to our section on catchment protection) ensures this high standard of water qualilty is maintained.
