Question juridique clé
Whether the water fee structure, including a high base-fee share, was lawful
Solution extraite
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.
Motifs extraits
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.
