(1)
Storage assembly operators should report beginning and completion of tank filling operations.
(2)
Operators at lead pumping station should track status of advancing water column during packing operation.
During startup, they should monitor overall performance of system.
(3)
Once operation of complete system begins, operators on each pumping station must continue to monitor
suction and discharge pressures. They must report low suction pressure or high discharge pressure and take
corrective action immediately.
2-10. Operation of Lead Pumping Station. Open butterfly valves on pump suction. Refer to applicable technical
manual for the operation of the 600 GPM pump.
2-11. Operation of Boost Pumping Station. Open butterfly valves on suction and discharge lines and close the
butterfly valve on the bypass line. Reference applicable technical manual for the operation of the 600 GPM pumping
assembly.
2-12. Operation of Storage Assemblies. Reference applicable technical manual for the operation of 20,000 gallon
storage tank.
2-13. Operation of Distribution Points. Operation of distribution points can begin when storage tanks contain enough
water to allow a normal discharge rate. Refer to applicable technical manuals for the operation procedures for the 125
GPM centrifugal pump and the hypochlorination unit.
a. Set flow rate of hypochlorination unit to 14 GPM.
NOTE
Do not confuse the terms "dosage" and "residual".
Dosage refers to the amount of chlorine added to the water.
Residual refers to the amount of chloride remaining in the water after 10 minutes.
b. If chlorine requirement is unknown, start with 1.0 percent solution strength (5.00 ppm, 10 oz of hypochlorite).
NOTE
Thirty minute contact time is required to obtain an accurate chlorine residual as prescribed by
TB-MED-577 or by area medical officer.
c. Perform chloride residual tests as follows (Figure 2-29):
(1)
Place chlorine color disc (1) in the comparator (2).
(2)
Place prism eyepiece (3) over sample cell windows (4).
(3)
Select two clean comparator cells (5).
(4)
Fill one cell (1, Figure 2-30) to the mark with the water under test.
