Use
Emptying
The longer polluted water has been in the tank
the greater the risk of nuisance from smell.
Therefore, never leave a waste water tank filled
unnecessarily long, but pump the tank empty
or have it pumped empty once a week, or
whenever possible.
Pumping empty can be done in two ways:
1. by connecting a shore pumpout system to
the deck cap to pump the tank empty.
2. by using a pump present on the ship to
pump out the waste water directly over
board through the deck cap and a hose
connected to this. This pump must have in
ternal diameter of minimum ø 38 mm (1½
inch).
N
ote
Pumping waste water directly
overboard is in many places absolutely
not allowed!
If the tank is pumped empty by a high capacity
pump there is a risk of the tank collapsing due
to the reduced pressure caused. This problem
occurs particularly when using the pumpout
systems. The following measures can be taken
to prevent collapsing from occurring:
open the inspection cover on the tank
open a shutoff valve fitted to the tank for
this purpose
install an automatically working blow valve.
During your absence
The water in the siphons can evaporate when
no use is made of washbasins, showers etc. for
a long time (siphons act as smell traps in the
pipes). This causes smell nuisance. Therefore,
place plugs in all drains when the ship is not to
be manned for a longer period.
Disinfect the tank and pipes at least once a year
preferably at the end of the sailing season.
Cleaning
‘Grey water’ tank
Clean the inside of the tank with water and a
good degreasing household cleaner; use a
brush or a sponge for a rigid tank. Rinse the
tank with clean tap water.
‘Black water’ tank
Clean the inside of the tank with water and a
good toilet cleaner; add cleaning vinegar if
there are lime deposits; use a brush or a sponge
for a rigid tank. Rinse the tank with clean tap
water.
If required, add to reduce odors ‘Tank Fresh’.
Disinfecting
Disinfect the tank by filling it with a solution
of bleach in water (1: 1000). Circulate this dis
infecting mixture through the waste water sys
tem. Remove the solution and rinse the tank
with clean tap water.
