5. Risk assessments

The regulations require the council to carry out a risk assessment of private water supplies every five years. This involves surveying the supply to identify potential contamination from the source to the consumer's tap.

Possible prevention measures and treatment options are identified to protect residents’ health. The results of the risk assessment help to identify which parameters need to be tested when sampling the water supply and act as a reference when determining potential causes of failure.
