Its correct during non monsoon periods only 1/20th to 1/30 th of design discharge will be passing through the sewers if combined system is adopted.

I think it is 5.

How it is 20 I think it should be 5.

Can anyone explain it please?

How it is constant?

Percentage discharge in non monsoon will eliminate water coming through storm. So, as in sewer there will be sewage and drainage but in non monsoon it is only sewage.

So percentage discharge would be = Qs*100/(Qs+Qd) = 100/21.

Sewer are generally combined with drainage waste and domestic and industrial waste. Drainage is nothing but the storm water.

In case of non monsoon there will be no waste from drainage (storm drain) so the value is constant.
