The quality of tap water in Espoo, Kauniainen, and Kirkkonummi was excellent in 2024, according to monitoring by Espoo Regional Environmental Health.
Nine water utilities supply drinking water in these areas, with the largest provider being Helsinki Region Environmental Services Authority (HSY). Several smaller water cooperatives also operate in Espoo and Kirkkonummi, though they do not produce or treat water themselves.
Water quality is assessed based on microbiological and chemical criteria set by law. These include testing for bacteria, metals, and other compounds.
All samples taken in 2024 met the required microbiological and chemical safety standards. However, two samples exceeded the guideline limits for bacterial colony counts, and two others had slightly elevated iron levels. These deviations were not considered a health risk.
Authorities test tap water based on supply volume and risk assessments. Larger suppliers, such as HSY, undergo frequent testing, with samples taken almost weekly. Smaller water cooperatives are tested annually. In 2024, more than 200 official water samples were collected.
There were 12 water quality incidents recorded last year. In nine cases, restrictions were placed on water use until additional testing confirmed safety. Environmental health authorities worked closely with water suppliers to manage these situations.
Tap water testing results from utilities serving at least 50 people or supplying 10 cubic metres per day are available at vesi.fi.
Espoo Regional Environmental Health advises residents to flush tap water before use, especially for drinking or cooking. Running the tap improves quality by ensuring fresh water from the mains. Water is ready for use once it feels cool and stable in temperature. If a tap has not been used for a long period, flushing for several minutes may be necessary.
