 Mahendra K said: (Jan 16, 2017) How it's?

 Praveen Bhaskar said: (Jun 26, 2017) Maximum daily flow = 2*avg. Daily flow. (In this case diameter do not matter).

 Debasish said: (Jun 29, 2017) Maximum daily flow = Two times the annual average daily flow (representing seasonal variations). Maximum hourly flow = 1.5 times the maximum daily flow (accounting hourly variations). = Three times the annual average daily flow.

 Kapil Dev Sharma said: (Jul 14, 2018) Mains up to 1m in dia = 2. Branches up to 0.5m into = 3.

 Avi said: (Aug 30, 2018) MAX FLOW = 2 x average flow. Max flow = 4 x minimum flow.

 Sunil Meena said: (Oct 2, 2018) Main sewer upto diameter 1m = 2. Branch sewer upto diameter .5m = 3. Lateral sewer upto diameter .25m = 4.

 Sanket said: (Sep 26, 2019) Trunk mains above 1.25m in dia 1.5.

 Amitesh said: (Jan 2, 2020) Max flow is 3 times of avg flow please correct.

 Abubakar said: (Jan 20, 2021) Above 1.25 = 1.5, Upto 1 = 2.0, Upto .5 = 3.0, Upto .25 = 4.0. Reference S.K. Garg.
