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
