The Water Supply (Water Quality) Regulations 2001 (revoked)

Authorisation of supply points E+W

8.—(1) The National Assembly for Wales, being satisfied that analysis of samples taken from—

(a) any blending point;

(b) the water leaving any service reservoir which receives water from a treatment works before its supply to any consumer; and

(c) the water leaving any treatment works,

will produce data in respect of the parameters specified as items 7, 8 and 9 to 25 in column (1) of Table 3 in Schedule 3 which are unlikely to differ in any material respect from the data that would be produced in respect of those parameters from analysis of samples obtained from sampling points, hereby authorises the use for the purposes of regulation 6 of samples in relation to those parameters taken for a water supply zone from a blending point, a service reservoir of that description or a treatment works.

(2) Subject to paragraph (3), the National Assembly for Wales may, in relation to any parameter other than a parameter referred to in paragraph (1), on the written application of a water undertaker [F1 or on the joint written application of a water undertaker and combined licensee], authorise the use for the purposes of regulation 6 of samples taken for a water supply zone otherwise than from a sampling point; and any such authorisation may extend to all samples in relation to that parameter or to such number or proportion of those samples as is specified in the authorisation.

(3) The National Assembly for Wales shall not grant an authorisation under paragraph (2) unless it is satisfied that analysis of samples taken from a point other than a sampling point will produce data in respect of the parameter in question which are unlikely to differ in any material respect from the data that would be produced in respect of that parameter from analysis of samples obtained from sampling points.

(4) Subject to paragraph (5), the National Assembly for Wales may at any time modify or revoke an authorisation under paragraph (2).

(5) Unless it appears to the National Assembly for Wales that the immediate modification or revocation of an authorisation under paragraph (2) is required in the interests of public health, it shall not modify or revoke such an authorisation without giving to the water undertaker to which the authorisation relates at least six weeks’ notice of its intention to modify or revoke.

(6) A water undertaker shall notify the National Assembly for Wales as soon as it has reasonable grounds for believing that an analysis of samples taken for a water supply zone from a point other than a sampling point would produce data in respect of the parameter in question which would differ in a material respect from the data produced by an analysis of samples taken from any of the sampling points within that zone; and the National Assembly for Wales shall thereupon, and without the need for prior notice to the water undertaker, revoke the authorisation.
