Do we need to consider contributing flow from housing/industrial area in order to compute peak flow in drain, since MSMAM only outlines consideration of flow from rainfall (ARI)?

MSMA outlines consideration of flow from rainfall (ARI)?

>>>I think you meant by this:
MSMA says you must consider the rainfall on a catchment when computing the runoff.

housing/industrial area in order to compute peak flow in drain,

>>>If what I said is true then you must consider the runoff from any contributing catchment area whether it is housing/industrial use.
