Roof drains, yard drains, sump pumps and other piping shall discharge
to infiltration or vegetative BMPs and, to the maximum extent practicable,
satisfy the criteria for disconnected impervious areas (DIAs). When
it is more advantageous to connect directly to storm sewers, such
connections may be permitted by the Township with written authorization
from the Township. Roof drains, yard drains, sump pumps and other
piping shall not discharge directly to streets.
