Explain the design procedure for sanitary and storm sewer? According to your observation which type of sewer system is more effective? A catchment is having total area of 60 hectares. The rainfall intensity relation with duration ii. for this catchment is given by the relation I=100/(t+20),Where I is in cm/h and t is duration of rain in min. a) What will be the storm water runoff from this catchment if the average imperviousness factor is 0.64, and time of concentration is 35 min? b) If population density of the area is 350 persons per hectare and water consumption is 180 LPCD, what will be the design discharge for separate system and combined system?

Transcribed Image Text:Explain the design procedure for sanitary and storm sewer? According to your observation
which type of sewer system is more effective?
A catchment is having total area of 60 hectares. The rainfall intensity relation with duration
ii.
for this catchment is given by the relation I=100/(t+20),Where I is in cm/h and t is duration
of rain in min.
a) What will be the storm water runoff from this catchment if the average imperviousness
factor is 0.64, and time of concentration is 35 min?
Transcribed Image Text:b) If population density of the area is 350 persons per hectare and water consumption is
180 LPCD, what will be the design discharge for separate system and combined
system?
