Regulation 19 (Authorisations of different standards)

Regulation 19 makes provision for any relevant person to apply to the local authority for an authorised departure – that is, to supply water to a lower standard on a temporary basis while remedial action is taken as part of an agreed and timed programme of work. The likelihood of there being a basis in law for an authorised departure is diminishingly small.

The provision to apply for derogations still exists, and, if specific circumstances arise such as a new parameter being detected, the local authority can consider issuing authorisations, assessed and evidenced on a case by case basis. A local authority considering granting an authorised departure should approach the Inspectorate for advice on the specific case under consideration.
