TM 10-4320-303-132.8 PREPARATION FOR MOVEMENT.2.8.1 ProceduresforPreparationforMovementofTWDS.This paragraph provides general information formovement of TWDS equipment. Detailed instructions for the movement of each major component will beprovided in paragraphs 2.8.2 through 2.8.6.a. Preparing TWDS for movement requires the following:(1) Removing water from system.(2) Shutting down and disassembling major components.(3) Repacking major components.b. Remove water at lead pumping station first, then move down the line to the last boost pumpingstation. After hoseline water has been removed, empty storage tanks and begin to disassemblemajor components.c. To begin emptying hoseline, reference applicable technical manual and shut down lead pump. Closebutterfly valves on suction and discharge ports of lead pump. Run boost pumping stations in manualmode until suction pressure drops to 10 psi. Shut down boost pumping stations.CAUTIONDo not operate 600 gpm pumping assemblies below 10 psi. Damage to 600 gpmpumping assemblies may result if they are operated below 10 psi.d. Close butterfly valves on suction and discharge ports of boost pumping stations.e. Once all pumping stations have been shut down and isolated from hoseline, use 125 GPM pumpingassembly to drain storage tanks. Empty solution from reservoirs on hypochlorination units.Temporarily leave units in operation to flush parts with untreated water. After flushing for 10minutes, disconnect hypochlorination units and continue to empty storage tanks. Detailedprocedures for removing water from storage tanks are provided in paragraph 2.8.6.f. Pumping stations can be disassembled when they are shut down. Distribution points can be partiallydisassembled while storage tanks are being drained, and completely disassembled when tanks areempty. Storage assemblies can be disassembled when tanks are collapsed.g. Begin hoseline shutdown at the first 500 foot length and move down the line. Move air compressordown two hose lengths. Evacuate trailing hose, then load hose length to minimize number of timesair compressor is to be moved. Repack hoseline lengths when they are evacuated and collapsed.Personnel repacking hoseline segments can follow behind those evacuating and collapsing hoseline.Suspension devices, road crossing guards, and the pressure-reducing valve assembly that wereplaced along hoseline route are removed when crews reach installation sites.h. The pumping stations, storage assemblies, and distribution points can be repacked in any sequence.Pack the 10-mile hoseline segment crate, containing kits required to repack the hoseline, last.i. Pack all components for the six pumping stations in one crate, except for trailer-mounted pumpassemblies. Refer to applicable technical manual for preparation of movement for 600 GPMpumping assemblies. Collect pumping station components and packing materials at a single sitebefore repacking crate. Otherwise, all packing materials must be shuttled to each installation site forpacking.2-89
