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.

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

Ans is 5.
Q= Qd+ Qs = 21 Qs (wet weather) and Q =0 +Qs in dry weather. So discharge in dry weather is (1/21) * 100 = approx 5%
Q= Qd+ Qs = 21 Qs (wet weather) and Q =0 +Qs in dry weather. So discharge in dry weather is (1/21) * 100 = approx 5%

How it is 20 I think it should be 5.
Can anyone explain it please?

21 = 100%.
1 = 100/21.
4.76 = 100 * 4.76/21 = 22 = 20.
1 = 100/21.
4.76 = 100 * 4.76/21 = 22 = 20.

Qd/Qs=20.
So, Qd=20xQs.
Q= Qd+Qs.
Q= 20Qs+Qs. = 21Qs.
So, Qd=20xQs.
Q= Qd+Qs.
Q= 20Qs+Qs. = 21Qs.
