S.L. 449.63 Art. 11Risk assessment of domestic distribution systems.  S.L. 465.03.   S.L. 465.04.

(1) Risk assessment of domestic distribution systems shall comprise of the following elements:

(a) a general analysis of the potential risks associated with domestic distribution systems, and with related products and materials, and whether those potential risks affect the quality of water at the point where it emerges from the taps that are normally used for water intended for human consumption. This general analysis shall not entail an analysis of individual properties; and

(b) monitoring of the parameters listed in Part D of the Second Schedule in premises where specific risks to water quality and human health have been identified during the general analysis performed under paragraph (a):

Provided that in relation to Legionella or lead, the competent authority may decide to focus the monitoring referred to in paragraph (b) on priority premises.

(2) When the competent authority identifies, on the basis of the general analysis carried out under sub-regulation (1)(a), that there is a risk to human health stemming from domestic distribution systems or from the related products and materials, or when the monitoring performed in accordance with sub-regulation (1)(b) demonstrates that the parametric values set out in Part D of the Second Schedule are not met, the competent authority shall ensure that appropriate measures are taken to eliminate or reduce the risk of non-compliance with the parametric values set out in Part D of the Second Schedule:

Provided that in relation to Legionella, those measures shall target at least priority premises.

(3) Sub-regulation (2) shall be without prejudice to the provisions of the Control of Legionella Regulations and the

Registration of Cooling Towers and Evaporative Condensers

Regulations.

(4) In order to reduce the risks connected with domestic distribution across all domestic distribution systems, the competent authority assisted by supporting entities shall ensure that all of the following measures are considered and that those measures considered relevant are taken to:

(a) encourage owners of public and private premises to carry out a risk assessment of the domestic distribution system;

(b) inform the consumers and owners of public and private premises about the measures which aim to eliminate or reduce the risk of non-compliance with the quality standards for water intended for human consumption due to the domestic distribution system;

(c) advise consumers about the conditions of consumption and the use of water intended for human consumption, and about possible action to avoid the reoccurrence of those risks;

(d) promote training for plumbers and other professionals dealing with domestic distribution systems and the installation of construction products and materials that come into contact with water intended for human consumption;

(e) in relation to Legionella, ensure that effective control and management measures which are proportionate to the risk are in place to prevent and address possible outbreaks of the disease; and

(f) in relation to lead, if economically and technically feasible, implement measures for substitution of components made of lead in existing domestic distribution systems.
