Quantity = Per capita sewage contributed per day x Population.(a) True(b) FalseThis question was addressed to me at a job interview.My question is from Principle for the Preparation of Water Supply in section Valuation, Reports Technical and Design Data of Civil Engineering Drawing

Answer»

The correct answer is (a) True

To explain I WOULD say: Wastewater Quantity Estimation – The flow of sanitary sewage ALONE in the absence of storms in dry season is known as dry weather flow (DWF).

Sanitary sewage is mostly the spent WATER of the community draining into the sewer system. It has been observed that a small portion of spent water is lost in evaporation, seepage in GROUND, leakage, etc. Usually 80% of the water supply may be expected to REACH the sewers.
