Benefit: Groundwater

About 61% of the communal water supply originates from groundwater deposits. The communal water supply has been approximately 410 million cubic metres annually in recent years. About 90% of the population is inside the distribution network and 10% is dependent on their own water sources, most commonly private wells.

There are 6 020 classified groundwater areas in Finland which produce altogether 5.4 million m3 groundwater every day. More than half of these deposits are suitable for water supply and most of them have been assessed as good in quality. About 350 deposits were considered being at risk and 98 of them had bad water quality in 2013. In recent years the water quality has weakened in about a hundred deposits.
