Requirement to carry out a risk assessment

6.—(1) A local authority(1) must carry out a risk assessment for every private water supply in its area and review and update that risk assessment every 5 years (or earlier if it considers that the existing risk assessment is inadequate).

(2) In the case of a supply provided to a single dwelling, the duty in paragraph (1) applies only where that supply is provided as part of a commercial or public activity or as part of a domestic tenancy.

(3) In the case of a supply provided to a single dwelling not falling within paragraph (2), a local authority must carry out a risk assessment if requested to do so by the owner or occupier of that dwelling.

(4) A risk assessment must—

(a) establish whether there is a significant risk of supplying water that would constitute a potential danger to human health;

(b) satisfy the requirements of the Security of Drinking Water Supply Guidelines for Risk and Crisis Management(2); and

(c) take into account the results from the monitoring programmes established by the second paragraph of Article 7(1) of Directive 2000/60/EC of the European Parliament and of the Council(3).

(5) A local authority must within 12 months of having carried out a risk assessment provide the Welsh Ministers with a summary of the results of that assessment.
