Water treatment to minimise contamination from pipesE+W
29.—(1) Paragraph (2) applies where there is a risk (“the prescribed risk”) that water supplied by a relevant supplier would, for the reason mentioned in paragraph (3), after leaving the relevant supplier's pipes—
(a)contain a concentration of copper in excess of 2mg/litre, or
(b)contain a concentration of lead in excess of 10µg/litre.
(2) Every water undertaker or [F1wholesale licensee] which introduces water into the supply system used by the relevant supplier must, subject to paragraph (4), treat the water in such a way as will, in its opinion, eliminate the prescribed risk or reduce it to a minimum.
(3) The reason referred to in paragraph (1) is the presence in the water of a concentration of copper or lead which is attributable to the fact that copper or lead is the major component of such a pipe as is mentioned in section 68(3) of the Act M1, or its associated fittings.
(4) Paragraph (1) does not require a water undertaker or [F2wholesale licensee] to treat water if—
(a)the treatment is unlikely to achieve a significant reduction in the concentration of copper or lead, or
(b)treatment is not reasonably practicable.
