Sanitary Sewer Design Wastewater Components and Flows
faculty.washington.eduConsider peak storm flow and assume base flow was the same at the same hour on previous day. Peak storm flow is 606,000 m3/d at t=35 h. Flow one day earlier (t=11 h) was 340,000 m3/d. Inflow is therefore: ( ) 33 Infiltration is difference between average, daily, non-storm-influenced, wet-weather and dry-weather flow: Normalize to system ...
