Drinking Water

Drinking water means water for human consumption and hygiene, whether delivered from taps, tanks, bottles or other sources. All water for household use should be of the same quality as drinking water. NIPH provides advice on drinking water, water supply and recreational water to central, regional and local authorities plus owners of water works and public swimming pools.

  2. UV Disinfection Units

    Ultraviolet radiation is rather a common method in Norway for the disinfection of drinking water. The development of highly efficient water radiation units in recent years has made UV disinfection reliable and economically competitive. According to the water works register at the Norwegian Institute of Public Health (NIPH), more Norwegian water works are using UV than chlorine disinfection, but most of these water works are relatively small. Today, Norway is among the leading nations in applying UV disinfection of drinking water.
