Question juridique clé
Whether the ordinary sewer connection fee for the agricultural building had to be reduced under § 31 KER.
Solution extraite
The ordinary sewer connection fee was owed in full because the building generated significant stormwater and surface runoff that justified connection to the mixed sewer system.
Motifs extraits
Under the mixed system, disposal capacity is driven by peak rainwater load, not only by wastewater discharge. The barn-stable had a large roof and forecourt producing substantial meteor water; a reduction is justified only where no surface water occurs.
