Drinking water quality
Supplying high quality drinking water at all times is a priority to us. Sometimes things can go wrong, so we've provided some information to help if your water doesn't seem right.
Over the course of a year some 300,000 water tests are taken and analysed, and of the water we supply, 99.96% meet drinking water quality standards at customer taps.
Your water can also be affected by work or incidents in your area. You can check for planned or emergency works near you with our In Your Area service below.
