A.4 Disinfestation, Disinfection or Cleaning Agents of
Waterworks Apparatus and Distribution Systems
With effect from 1st October 2015 a policy change has been implemented to the requirement for
regulatory approval of products and substances clearly intended to be used whilst plant/equipment is off
line. These products or substances are normally flushed away or their concentration is reduced to a
minimum, that gives rise to no, or negligible risk, to water quality, before the supply is resumed.
Since these substances and products are not intended to be introduced or applied to water intended to be
supplied for domestic purposes they do not come within the scope of regulation 31 and approval is no
longer required.
The current listings in section A4 below will however remain until the five year period of validity of the
existing approval has expired
During the approval process there is no evaluation of a product’s effectiveness, only of its safety in use.
An approval given in this section does not certify that the Authorities are satisfied that the product is
effective, but only that it is safe for use in accordance with the Instructions for Use supplied.
The fact that a product is approved does not justify any claim about its effectiveness.
Permission or consent for disposal of any wastewater generated to a sewer or watercourse must be
obtained from the relevant water Service Company, or Environment Agency in England and Wales or
Scottish Environment Protection Agency (SEPA) in Scotland as appropriate.
