for a person 135 lt/day: 90- domestic purpose, 45- flushing


Dear Sir

We need to know whether this is a metro city /non metro. Whether there is proper sewer lines or not.

In case of non -metro - 135 Lpcd holds good.
In case of Metro - 150 lpcd.

In case it is for a Villa / gate property with duplex/multi level construction style - then it is better u go for 200 LPCD, (devoid of bath tub)

90% of total water supplied can be taken as a sewage.
