2-11. ASSEMBLY AND PREPARATION FOR USE - cont.
g
Assemble Boost Pumping Stations. Refer to figure 2-16.
WARNING
To prevent contamination of water system and damage to components,
keep rocks, dirt, mud, sand and debris from entering open couplings and
hoses during assembly
NOTES
Assembly of one boost pumping station is shown. Assembly of three remaining
boost pumping stations is similar.
The TWDS Is supplied with six 600 gpm pumps. Only five pumps are used
during normal operation. The sixth pump is kept as a spare.
All components used to assemble the pumping stations are 6-inch diameter.
Refer to paragraph 2-11e to install coupling clamps.
(1)
Assemble and prepare 600 gpm pump for use. Refer to the applicable TM.
(2)
Position 600 gpm pump so that suction port is pointing upline to the water source.
Suction Line.
(3)
Connect 6-inch x 10-foot discharge hose (12) to suction port on 600 gpm pump with coupling
clamp (11).
(4)
Connect butterfly valve (14) to 6-inch x 10-foot discharge hose (12) with coupling clamp (13).
(5)
Connect lateral pipe fitting (wye) (16) to butterfly valve (14) with coupling clamp (15).
Discharge Line.
(6)
Connect check valve (2) to discharge port on 600 gpm pump with coupling clamp (1). Arrow on
side of valve must point away from pump.
WARNING
To prevent injury to personnel, open port of pressure relief valve must
point away from water pump.
(7)
Connect pressure relief valve (4) to check valve (2) with coupling clamp (3).
(8)
Connect 6-inch x 20-foot discharge hose (6) to pressure relief valve (4) with coupling clamp (5).
(9)
Connect butterfly valve (8) to 6-inch x 20-foot discharge hose (6) with coupling clamp (7).
(10)
Connect lateral pipe fitting (wye) (10) to butterfly valve (8) with coupling clamp (9).
