Giải thích
CPC 1101.0 and related sections require storm drainage to be conveyed by an independent system rather than combined with sanitary drainage, except where a combined system is specifically approved. Mixing them can overload the sanitary sewer and treatment system during rain. Planning separate systems on the drawings keeps the layout compliant.
