Question

Quizplus · Accepted Answer

A 15-foot by 10 foot by 8-foot deep detention basin with a required detention time of 60 minutes can treat approximately 0.22 MGD.
Solution: Basin Volume = length x width x depth
Given 7.48 gallons = 1 cubic foot
Basin Volume = (15 ft) x (10 ft) x (8 ft) x (7.48 gallons/cubic feet)
= 8,976 gallons
Flow Rate = 8,976 gallons/60 minutes
= 149.6 gallons/minute
149.6 gallons/minute x 1,440 minutes/day = 215,424 gallons
(approx. 0.22 MGD)
