Discharging drinking water to shore
Make sure discharge hose is properly deployed, valves are properly set, and shore facility is ready to receive
Make sure storage tanks are being tilled per instructions In paragraph 34.
EMS monitors water level in each storage tank and amount of
chlorine In water entering tanks. It also monitors salinity, flow rate,
pressure, and total amount of drinking water being discharged.
Make sure EMS Is operating If not, start up by following procedures in TM 55-1930--209-14&P-11.
Position drinking water valves as follows
o = open
x = closed
Discharge pump used
'On Barges 2 and 3 only
Open drain valve(s) of storage tank(s) to be drained as shown In table below Make sure valves of tank(s) not
being drained are closed
To prevent operating shore discharge pump when dry, make sure
that drain valve (DW6, DW7, DW8, or DW9) of tank selected on
selector switch Is open.
On drinking water tank and shore discharge pump selector switch (Figure 3-1 ), position switches as follows
(1) Set pump selector switch to pump 1 or pump 2.
Normally, all four tanks are filled and drained at same time. In this
case, tank selector switch can be positioned to any of the four tank
numbers (1, 2, 3, or 4). However, when all four tanks are not being
drained, tank selector switch must be positioned to a tank number of
any of tanks being drained.
(2) Position tank selector switch (Figure 3-1) to number 1, 2, 3, or 4 tank to be drained. High and low level
switches on liquid level Indicator (Figure 3-2) of tank selected then automatically start and stop pump
selected In step 1.
(3) Close switchboard circuit breaker P9 for shore discharge pump 1, or circuit breaker P15 for shore
discharge pump 2.
When high level switch senses a full tank, discharge pump starts
automatically if motor controller HAND/OFF/AUTO switch is on
AUTO. When low level switch senses tank is empty, pump stops
On discharge pump motor controller of pump selected in step f(1), close main switch (Figure 3-1) to ON.
Then position HAND/OFF/AUTO switch to AUTO.
