My water quality

In the United Kingdom we have some of the highest standards of water quality and safety in the world.

We clean, disinfect and test your drinking water thoroughly, to make sure it’s safe to use, before it leaves our treatment sites and ends up at your taps.

However, sometimes your water can look, taste or smell different to usual. Often this is harmless, with a simple explanation for the change and an easy way to fix it.

Here we describe some common water quality problems, and how they can be solved.
