Figure 2-44. Sandbag Installation.
b. If 20,000 gallon pillow tank (Figure 2-44, 1) rolls when being filled, place sandbags (2) along edge of
20,000 gallon pillow tank (1) to prevent further rolling.
c. Whenever a 20,000 gallon pillow tank (1) is being filled, inform operators at downline pumping
stations to expect reduction in hoseline pressure. The reduction in pressure can cause engines on
downline stations to reduce speed. Whenever possible, do not fill 20,000 gallon pillow tank(s) (1) at a
rate that causes downline pumping stations to reduce speed.
d. When 20,000 gallon pillow tank is full, close 4 inch gate valve (Figure 2-43, 1).
2.5.5 Operation of Distribution Points .
2.5.5.1 Distribution Point General Operating Procedures .
a. Before placing distribution point in operation, determine proper strength of hypochlorite solution, para
2.5.5.3.
b. After solution strength has been determined, reference applicable technical manual and start 125
GPM pumping assembly. Prepare solution and place hypochlorination unit into operation,
paragraphs 2.5.5.4, 2.5.5.5, or 2.5.5.6. When hypochlorination unit has been adjusted, open gate
valves in hoseline network. Water may now be distributed at manual disbursing stations.
c. When distribution point is not being used refer to applicable technical manual and shut down 125
GPM pumping assembly. Hypochlorination unit will stop automatically. Make sure nozzles and
elbow valves are hanging from nozzle stand assemblies. If distribution point will not be used for a
long period refer to paragraph 2.3.9.2 step an and install dust plugs on elbow valves and nozzles.
d. If hypochlorination unit stops working properly or residual test, para 2.5.5.7, does not give satisfactory
reading, immediately shut down operation of distribution point. Notify other operators and take
corrective action.
