2-19. OPERATIONS IN DUSTY OR SANDY AREAS - cont.
(7) Following operation in dusty or sandy areas, rinse all components with clean, fresh water to
remove sand, dust and grit. Direct special attention to quick disconnect coupling gaskets and
2-20. OPERATION IN SALT WATER AREAS.
Operation in salt water areas accelerates corrosion on bare metal surfaces. Observe the following
precautions when operating the water system in this environment.
(1) Carefully inspect water system components during installation. If bare metal is found, notify unit
maintenance to preserve or paint the metal as required.
(2) Refer to the applicable TM for operation of the 600 gpm pump in salt water areas.
(3) Refer to the applicable TM for operation of the 125 gpm pump in salt water areas.
(4) Refer to the applicable TM for operation of the hypochlorination unit in salt water areas.
(5) Refer to the applicable TM for operation of the 20K collapsible fabric tanks in salt water areas.
(6) Following operation in salt water areas, rinse components with clean fresh water, to remove salt
spray and/or deposits.
2-21. EMERGENCY PROCEDURES.
The TWDS provides sufficient water storage and pumping capacity to allow isolation and redirection of water
flow around failed pumping components without a severe drop in operational capacity. Failure of the lead
pumping station 600 gpm pump will require replacement of the pump for continued system operation.
Lead Pumping Station Failure Refer to figure 2-30.
To prevent damage to the equipment, downline boost pumping stations must be shutdown if lead
pumping station is inoperable.
(1) Shutdown boost pumping stations (para 2-13d).
(2) Shutdown 600 gpm pump at lead pumping station (para 2-13d).
(3) Close valves L1 and L2.
(5) Remove lead pumping station components from 600 gpm pump (para 2-16i).
(6) Remove defective 600 gpm pump from water system.
(7) Position spare 600 gpm pump in lead pumping station.
