(a) when supplying water to any premises for domestic purposes to supply only water which is wholesome at the time of supply; and

(b) so far as reasonably practicable, to ensure, in relation to each source or combination of sources from which that undertaker supplies water to premises for domestic purposes, that there is, in general, no deterioration in the quality of the water which is supplied from time to time from that source or combination of sources.

(2) For the purposes of this section and section 53 below and subject to subsection (3) below, water supplied by a water undertaker to any premises shall not be regarded as unwholesome at the time of supply where it has ceased to be wholesome only after leaving the undertaker’s pipes.

(3) For the purposes of this section where water supplied by a water undertaker to any premises would not otherwise be regarded as unwholesome at the time of supply, that water shall be regarded as unwholesome at that time if—

(a) it has ceased to be wholesome after leaving the undertaker’s pipes but while in a pipe which is subject to water pressure from a water main or which would be so subject but for the closing of some valve; and

(b) it has so ceased in consequence of the failure of the undertaker, before supplying the water, to take such steps as may be prescribed for the purpose of securing the elimination, or reduction to a minimum, of any prescribed risk that the water would cease to be wholesome after leaving the undertaker’s pipes.

(4) The provisions of this section shall apply in relation to water which is supplied by a water undertaker whether or not the water is water which the undertaker is required to supply by virtue of any provision of this Act.
