Kernrechtsfrage
Whether a sewer connection fee may be calculated by reference to the building insurance value rather than actual use.
Extrahierter Entscheid
Yes. The building insurance value is an admissible, schematic basis for the connection fee; actual use is decisive only for usage and treatment fees.
Extrahierte Begründung
The connection fee is a causal charge for the availability of the public sewer system. The law may use the building insurance value as a workable proxy for the owner’s interest in the municipal service.
