Storm Water Runoff Sizing
• Determine discharge requirements (ppm)
• Calculate rainfall (in/hr)
• Calculate flow source area (ft2)
• Calculate treatment rate (GPM)
(GPM) = Area(ft2) x Rainfall
(in/hr/ft2) x 0.0104 (GPM/in/hr)
Storm Water Sizing Example
• 42,000 Sq. Ft.
• Lawrence, KS (2 in/hr.)
• Conversion Factor – 0.0104
• 42,000 x 2 x 0.0104 = 885.25 gallons per minute
9,000 gallon OWS (900 gpm)
Other Water Storage Applications
• Fire Protection
• Potable Water
• Rainwater
• Onsite Septic
• Grease Interceptor
