AQUILA OPERATING MANUAL
NW Explorations
4P4: Holding Tank
There is a 40-gallon holding tank on the boat midships under the generator. Unless the Y-valves are set so the
heads pump overboard (see above), the sewage from each head goes to the holding tank.
4P5: Head Holding Tank Level Gauge
The boat is equipped with a tank level indicator in the aft head compartment, so it is easy to tell if a tank is full.
Check this indicator regularly and don’t flush if full!
4P6: Head Holding Tank Pumpout
If dumped overboard from this tank, the effluent passes through
a through-hull valve which is normally in the correct position. To
dump the tank, use a shore side pump out station connecting to
the “Waste” deck fitting on the foredeck inside the Portuguese
bridge to starboard.
4P7: Head Waste Overboard Pump
If not in U.S. waters or a “no-discharge zone”, you can dump
the tanks overboard without a pump out station by turning “ON”
the macerator pump at the DC panel. Leave it on until you hear
the pump run free. This pump is under the master stateroom
berth’s foot. Do not leave the pump running dry for long as it will
damage the pump!
It takes about ten minutes to empty a full holding tank. The best way to monitor it is to run it until bubbles come
out from under the starboard side of the hull.
If it is emptied while underway, have someone monitor the operation, checking the tank level
indicator to be sure that the pump is not forgotten and left running, lest you ruin the pump!
4P8: Head Y-Valves
Each head is equipped with a Y-valve located on the forward side of each
fuel tank in the engine room. In US.
Waters, the
Coast Guard Rules require that the valves be “secured” in the holding tank position to assure that
all effluent will be kept aboard in the tank. If you turn the valve to overboard while in Canadian waters, re-
secure it with the wire ties supplied and stored near the valve when you return to the U.S.!
Holding tank gauge is inside cabinet
door above aft stateroom sink.
(Note the outlet also in a cabinet here.)
