Key legal question
Whether the water fee structure, including a high base-fee share, was lawful
Extracted holding
Yes. The municipality could levy both a base fee and a consumption fee, and the resulting allocation did not violate federal or cantonal law or the equivalence principle in this case.
Extracted reasoning
Federal law left municipalities wide discretion for water fees; cantonal law required a base and a consumption fee but set no fixed ratio. The appellant's property had unusually low water use, while water supply costs were largely fixed and related to network availability, not actual consumption.
