A. Determine pump capacity -
Gravity Distribution
1. Minimum suggested is 600 gallons per hour (10 gpm) to stay ahead of
water use rate.
2. Maximum suggested for delivery to a drop box of a home system is 2,700
gallons per hour (45 gpm) to prevent build-up of pressure in drop box.
Pressure Distibution
3. a. Select number of perforated laterals
b. Select perforation spacing = 3 feet.
C. Su ct 2 ft from the rock layer length.
- 2 ft. = Co(0 feel
d. Detemnne the number of spaces between perforations.
Length perf. spacing = L. L, ft. • -,7,- ft. _ ZI.a spaces
e. �-I spaces+ 1 = ay perforations/lateral
f. Multiply perforations per lateral by number of laterals to 1)JU-0ta.

g. x � _ gpm.
SELECTED PUMP CAPACITY -?!2_ gpm
B. Determine head requirements:
1. Elevation difference between pump and point of discharge.
s feet
2. If pumping to a pressure distribution system, five feet for pressure
required at manifold if gravity s stem, zero.
S feet
3. Friction loss
a. Enter friction loss table with gpm and pipe diameter.
Read friction loss in feet per 100 feet from table.
F L. = D. L, ft./100 ft of pipe
b. Determine total pipe length from pump to discharge
point. Add 25 percent to pipe length for fitting
loss, or use a fitting loss chart. Equivalent pipe
length -1.25 times pipe length =
L4 �j- x 1.25 = :�O_ feet
c. C.lculate total friction loss by multiplying
K-tion loss in ft/100 ft by equivalent pipe length.
Total fr'cbon loss = D • 1, x !ro +100 = �_ feet
4. Total head required is the sum of elevation difference,
special head requirements, and total friction loss.

C. Pmnp selection
1. A pump must be selected to deliver at least
30) gpm (Step A) with at least i) feet of total head (Step B).
