Improvement programmes

Water companies, if required by the Inspectorate or with the agreement of the Inspectorate, can put in place programmes of remedial action to improve drinking water quality whenever these are necessary.

List of current Improvement Programmes by company.

Programmes of work arise in four ways:

  • as a result of the process for setting price limits for a five year period (known as the price review process);
  • as a result of enforcement for contraventions of the drinking water standards for parameters in the regulations; and
  • as a result of enforcement for issues arising out of an assessment by the Inspectorate of a drinking water quality incident or technical audit;
  • following the identification of a risk to health through a risk assessment of a water supply system.

More detail is provided in the Guide to Improvement Programmes.
