Water quality postcode search

Enter your full postcode in this box (e.g. EX2 7HR) to obtain the water quality in your supply zone.

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.

The results will be presented below and will provide:

  • your sewerage company
  • the latest water quality report
  • a map of your supply zone
  • water hardness information

A detailed map of our entire supply area is available here.
