A. The pump discharge capacity shall be based upon the perforation discharges for a minimum average head of 1.0 foot. Perforation discharge will be determined by the following formula:

Q = 19.65 cd2h1/2

where: Q = discharge in gallons per minute,

c = 0.60 = coefficient of discharge,

d = perforation diameter in inches, and

h = head in feet.

B. The pump discharge head shall be at least 5 feet greater than the head required to overcome pipe friction losses, and the elevation difference between the pump and the distribution device;

C. The quantity of effluent delivered for each pump cycle shall be no greater than 25% of the average design flow; and

D. A siphon will not be allowed as a dosing device to pressurize a system.
