Trondheim municipality wishes, as the waterworks' owner, to limit the run-off of natural fertilisers which can reach the source of drinking water. The clause for the Jonsvatnet catchment area therefor includes limitations for use of fertilisers involving some of the agricultural properties. Fertiliser agreements have been entered into with the involved farms, where the municipality shall transport all surplus fertilisers out of the catchment area.
