Water Approved Products
On 1st October 2000, the withdrawal of Regulation 25(1)C, the 'traditional use of exemption' provision in the Water Supply (Water Quality) Regulations 1989, came into effect for materials use in water supply pipes, service reservoirs and water towers.
Where concrete repair and protection products are destined for use in public supply systems the new regulations comprise the following requirements:-
Water undertakers must specify structural design to BS8007:1987.
The chemical identity of the components of the products must be in accordance with the substances specified in the 'List of Authorised material Components'.
Water undertakers must obtain a declaration from the concrete repair and protection product producer that the products do not contain chemicals other than those on the Authorised List. Products whose components are on the 'List' require no additional testing even for BS 6920 (Water Quality effect); in effect such products have been pre-approved by virtue of inclusion of their components on the List.
