Household water and well water

Good household water is safe to drink, good-tasting, clear and colourless.

Household water refers to the water used by households for drinking and cooking and by the food industry for product manufacturing. There are health-based quality requirements and recommendations for household water quality.

In Lahti, the environmental health department monitors the quality of the household water supplied by the water supply plant on a regular basis. The water supply plant also conducts its own usage monitoring regarding the distributed water.

The purpose of the monitoring is to ensure that the distributed water is safe to consume. Household water must not contain any organisms (bacteria, viruses or parasites) or substances (chemicals) in amounts that could be detrimental to people's health. If you detect issues with the quality of the supplied water, you can call Lahti Aqua Ltd's around-the-clock service number. If you suspect your network or well water is causing a health risk, contact Lahti's environmental health services as well.

Well water

Tests concerning the water quality of private wells are primarily the well owner's responsibility. You should have the quality of your well water tested by an approved water laboratory every three years even if you do not notice any smell or taste issues. You should contact the laboratory in advance for instructions regarding sample collection.
