1. 
Roof drains shall not be connected to streets, sanitary or storm sewers, or roadside ditches, except as provided in § 23-901, Subsection 2.

Roof drains and sump pumps shall discharge to infiltration or vegetative BMPs, where feasible, and to the maximum extent practicable satisfy the criteria for disconnected impervious areas; provided, however, that roof drains may be connected to streets, roadside ditches or storm drains upon determination by the Township Engineer that such connection is the only practical alternative or will provide other offsetting advantages.
