to be significant contributors to pollution to the waters of this

1. Roof drains shall not be connected to streets, sanitary or storm sewers, or roadside ditches, except as provided in §
23-901, Subsection
2.
2. When it is more advantageous to connect directly to streets or storm
sewers, connections of roof drains to streets or roadside ditches
may be permitted by the Township.
3. 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.
