My Services

My water quality

Our commitment

Always clean and safe. Always wonderful. Always on tap. Since day one, that’s our commitment to you. We work hard every single day to make sure that you have a fresh, clean water supply straight to your home. For now, and for future generations.


Safety in numbers

We look after 185 water treatment works and over 46,000km of water mains (that's more than enough to go around the Earth once!) day and night, all year around. We test your water over 500,000 times every year to make sure the highest standards are met for your supply, consistently achieving a pass rate of over 99.9%. We also have 1,100 continuous automatic analysers that track a wide range of parameters to make sure your water is safe and wholesome. It all adds up to a service you can not only trust for clean, fresh water, but you can also rely on long into the future.


Monitoring water quality

When it comes to testing the quality of your wonderful water, we always go the extra mile. We know how important it is to have fresh, clean water on tap straight to your home. We monitor from the source to your tap to maintain the quality of our water at every point of its journey to your home. No shortcuts. No excuses. No compromise.




Regulations and standards

We take providing wonderful, clean water to you very seriously. It’s why we support stricter laws, tighter regulations and more thorough testing; and why we openly make the information about the quality of your water available. In fact, you can check your own water any time you like. 



Schemes and partnerships

We’re dedicated to delivering a world-leading level of drinking water that's clean and safe for you to drink. This is why we work closely with our regulators and other water companies. By doing so we can  continue to innovate and improve our processes, all whilst meeting the latest water supply laws and regulations.

In the event you ever have a problem, please talk to us first and we’ll do our best to sort the issue out. If we’re unable to resolve it ourselves, we’ll refer you to the appropriate agency or consumer group.







Local authorities

City and district councils have public health responsibilities to oversee the provision of sufficient and wholesome water supplies. Environmental health departments usually administer these functions.
