Water balance
(K § 22 (1) of the Water Act)
(1) The water balance shall be compiled in the water catchment areas of surface water and in hydrogeological groundwater rajones for river basin areas, or for specific locations, and shall include the outputs to be used for decision-making by the water authorities, as well as the public authorities in decision-making under a specific legislation, (1) in particular for the determination of the amount of water available for the collection or determination of the permissible pollution of waste water discharged into surface or groundwater water in a specific location, for a cumulative assessment of surface and groundwater status and for reporting of water planning and other activities under the Water Law.
