The Drinking Water Inspectorate (DWI), which is responsible for regulating drinking water quality, has today published its Annual Report for 2021. It states that drinking water quality in Northern Ireland is of a high standard.
Northern Ireland Water Limited (NI Water) is required to undertake a stringent monitoring programme to verify that the tap water it supplies to consumers meets all the stringent quality standards set by the drinking water regulations. During 2021, over 95,000 tests were completed. As outlined in the DWI Report, the overall compliance for the mains water supply in 2021 was 99.88%. The results are based on samples taken from water treatment works, service reservoirs and consumers’ taps.
Welcoming publication of the report, Environment Minister Edwin Poots MLA, said: “I am pleased to endorse the Drinking Water Inspectorate’s annual report on Drinking Water Quality in Northern Ireland. The quality of our drinking water remains high which is vital for Public Health, the hospitality sector, farming and the economy.”
