Understanding your water

Our region is divided into a number of supply zones. A Water Supply zone is defined in order to enable the mandatory sampling programme to be undertaken at the correct frequency per populous. Each zone is a geographical area containing no more than 100,000 permanent residents.

Below, you’ll find useful information specific to your supply zone, including:

  • A map showing your water supply zone

  • The most recent water quality report

  • Details about water hardness in your area

We're committed to providing you with clear and transparent information about your water supply.
