This is over zealous regulations by the previous government, creating yet more beaurocracy in local government and unnecessary cost to householders.
The Private Water Supplies Regulations 2009. Passed by the previous government, these regulations require councils to enforce compliance with new water quality requirements. Affected households could be charged up to £500 for carrying out a "risk assessment" and further sums for sampling, investigating, and "granting an authorisation".
The 1998 EU Drinking Water Directive is intended to ensure mains water supplies meet good standards but states: "Member states may exempt water from an individual supply serving fewer than 50 persons."
However, the last government decided not to take advantage of the exemption, imposing burdens on users of spring water not demanded in other European countries.
Throw them on a bonfire of unnecessary regulations.
