The Public Water Supplies (Scotland) Regulations 2014

Risk assessment of each treatment works and its connected supply system

30.—(1) This regulation applies to each treatment works and its connected supply system from which water is supplied, or is to be supplied, by Scottish Water for human consumption purposes.

(2) Scottish Water must assess each treatment works and its connected supply system (“the combined system”) so as to establish whether or not there is a significant risk of supplying unwholesome water from the combined system (or any part of it).

(3) Each risk assessment must be recorded in writing (or in electronic form) and include—

(a) a description of the methods used to prepare it;

(b) where the assessment establishes that there is no significant risk of supplying unwholesome water from the combined system (or any part of it), a statement confirming this; and

(c) where it establishes that measures have been taken to remove a significant risk of supplying unwholesome water from the combined system (or any part of it)—

(i) monitoring data which verifies this; and

(ii) details of those measures.

(4) Subject to paragraph (5), each risk assessment must be completed (and recorded) before 1st October 2015.

(5) If the combined system (or part of it) is not in use on 1st January 2015, the risk assessment must be completed (and recorded) before the combined system or, as the case may be, that part of it) is used by Scottish Water to supply water for human consumption purposes.

(6) Scottish Water must keep each risk assessment under review.

(7) The Drinking Water Quality Regulator for Scotland may, by notice given to Scottish Water, require it to complete (and record) a risk assessment or, as the case may be, a review by a date specified in the notice.

(8) Where Scottish Water becomes aware of any factors which make it likely that a risk assessment or a review will establish that there is a significant risk of supplying unwholesome water, it must inform the Drinking Water Quality Regulator for Scotland specifying the relevant factors and the measures it is taking or intends to take to mitigate the risk.
