spillage catchment port drains in ROWPU space, and forward toilet deck drain in ROWPU space to aft void
2 port shell overboard discharge.
Nonoily liquid gravity draining from heating and air conditioning unit in workshop, drinking water fountain in
dayroom, and sink in dayroom to forward void 2 starboard shell overboard discharge.
Nonoily liquid gravity draining from two ROWPU spillage catchment starboard drains and forward starboard
deck drain to void 2 starboard overboard discharge.

5-10.2.1 Transferring bilge water from voids to sludge tank
When audible and visual alarms are activated and EMS BILGE ALARMS display
page (Figure 5-6) Indicate which void must be drained. When alarms are activated,
turn off alarms according to TM 55-1930-209-14&P-11.
At void bilge to be drained, connect 25-foot suction hose with foot valve to quick disconnect coupling on bilge
suction line and lower foot valve into bilge.
Open bilge drain (BD) valve listed below for bilge to be drained. Make sure all others are closed.
Bilge to be
Open valve no.:
Open valves BD7 and BD11. Close valve BD8.
On bilge pump motor controller, push main switch ON and press START button.
If monitoring system alarm sounds during operation, sludge tank is full. Bilge
pump must be stopped immediately.
When bilge is empty, stop bilge pump by pressing STOP button on motor controller.
Close valve opened in step b above and disconnect suction hose.
Repeat steps a thru f until all bilges are drained.
Immediately clean up any spills on decks.
Close valve BD11.
5-10.2.2 Transferring void bilge water to sludge facility
USCG regulations prohibit discharge of oil, fuel or chemically contaminated water
upon the navigable waters and contiguous zones of the United States. If such a
discharge causes a film or sheen upon or discoloration on the surface of the water
or causes a sludge or emulsion beneath the surface of the water, the USCG must
be notified by telephone or radio as soon as contamination takes place. As soon
as steps have been taken to stop spillage, the USCG must be contacted again.
Anyone violating these regulations is subject to a fine.
