Mains Water Quality
We monitor the quality of water supplied by water companies. Our sampling is usually limited to the investigation of complaints from local residents or businesses concerning strange tastes or bits in the water.
Water supply testing
Most properties within the Dorset area receive their water from a water company (mains supply), but some depend on smaller private water supplies.
Depending where you live, mains water is provided by either:
-
Wessex Water (opens in a new window)
-
South West Water (opens in a new window)
-
Sembcorp Bournemouth Water (opens in a new window)

These companies must rigorously test the quality of their supplies to check that they comply with national standards. The results are publicly available - usually on their websites.
