encounter. Some of these situations were studied in the computer analysis
with the following results:

(a) Pumping directly from Well NO. I to Tank No. 2 by-passing the Wham

booster station, with Tank No.1 valved off will cause pressures

in Zone A to increase appro~imately 70 psi over normal static pressure

for that zone.

(b) Transferring water from Tan~ No. 2 to Tank No. I at the maximum rate

of 128 gpm will raise press~res in Zone A by approxi~ately 10 psi and

pressures in Zone B will be lowered in pressure 5 to 10 psi.

I

(c) Pu~ping from Well No.4 directly to Tank No.3 by-passing the swimming

pool booster pump with Tank No. 2 valved off will raise pressures in

Zone B 45 to 50 psi greater than encountered under normal static condi-

t ions.

4. Adequacy of Line Sizes - The distribution system consists almost exclu~

sively of 4" diameter cast iron lines. The lines conveying water from the

storage tanks are also 4" in diameter. Under peak hour conditions, the highest

flow rates would occur in lines nearest to the storage tanks. Using both the

present and future peak hourly demands, the velocities in the 4" diameter pipe

don not warrent increasing the diameter of the existing line. However, larger

diameter pipes, i.e. 6" in diameter, near the storage tank would increase the

system's capabilities in transporting increased supply rates.
