TM 10-4610-237-122.17 EMERGENCYPROCEDURES.The 20K Water Storage and Distribution System allows isolation and redirection of water flow around failedcomponents without a severe drop in operational capacity.a.ComponentFailure. Refer to Figure 2-9. In the event of a hose, coupling, tank or valve rupture, the failedcomponent must be isolated as soon as possible to stop the loss of water.WARNINGTo prevent injury to personnel, do not attempt to grab whipping hose.(1) If ruptured hose is whipping, shut down water pump.CAUTIONTo prevent damage to the equipment, water system must be shut down if isolating failed component(s) willblock water flow to or from the 125 gpm pump connection kit.(2) Close nearest upstream and downstream control valves to stop water flow through failed component.(3) If failed component is located in the 125 gpm pump connection kit, shut down the 125 gpm pump.Refer to the applicable TM.(4) Continue operation with failed component isolated from the system.b.WaterTankFailure. Refer to Figure 2-9. In the event the water tank fails, water can be pumped directlyfrom a source through the hypochlorination unit to the loading stations.(1) Connect the water source to the input of the single tank connection kit.(2)Isolate tank from system by closing gate valves V2 and V3.(3) Open gate valves V1, V5, V6 and V4.(4) Start and operate 125 gpm pump. Refer to the applicable TM.(5) Operate loading stations in the usual manner.2-43
