IW have been given approval by the Commission for Regulation of Utilities to start charging people for using excessive amounts of water, above the 213,000L annual limit set by legislation. By the looks of it people will have plenty of time to conform and then there'll be a charge of €1.85 for each 1,000 litres above that limit. A sensible move in my view as there are an estimated 80,000 households going over the limit.
