Questione giuridica chiave
Under what conditions may a building permit be granted in non-zoned territory without a general sewer plan?
Decisione estratta
Permits may be granted only within the narrower building area, covering serviced land and land about to be serviced; connection to sewerage must be ensured, wastewater load must not exceed 12 population equivalents, and an adequate interim single-treatment facility must be provided.
Motivazione estratta
Art. 28 of the General Sewerage Ordinance refers expressly to Art. 19 GSchG and requires treatment as if a general sewer plan existed. The legislature intended permit decisions to proceed only where the connection is at least guaranteed; Art. 26(1) further specifies the timing of the connection and the transitional technical requirements.
