Introduction

These instructions apply to the Vetus flexible plastic waste water
tanks for grey water and black water.
Grey water tank
A grey water tank should only be used for collecting water
from the sink, shower, wash basin,air conditioning, etc..
The capacity of a waste water tank can never be too large.
Match the capacity to the amount of fresh water available; the
capacity of the water tank(s).
Fit sink, shower, wash basin, etc. with a drain with sieve, so
that coarse waste, such as hair etc., will be less likely to enter
the grey water tank.
Black water tank
A black water tank is used only for collecting toilet waste.
A black water tank should be installed in accordance with the
European Guidelines for Pleasure Boats (EGPB), ISO 8099
Standard.
The capacity of a waste water tank can never be too great.
The capacity should be calculated using the amount of flush-
ing water (outside water) used by the toilet. Reckon on 7 to 14
litres of black water per person per day.
Use only water-soluble toilet paper to prevent unnecessary
blockages.
N.B: Sanitary towels and tampons in the toilet and black water
tank will certainly cause blockages.
Clearing a blockage is an unpleasant job, make sure you have a
pair of rubber gloves on board.
Smell
Grey water tank
Unpleasant odours will be produced in every grey water tank.
Fit the sink, shower, wash basin, etc., with an S-bend (siphon
or stink trap) and a plug.
Black water tank
Unpleasant smells caused by faeces will be produced in
every black water tank. The use of sea water for flushing
will increase the smell. The algae in sea water also produce
unpleasant smells.
It is possible to add special additives to waste water tanks
to reduce the smell, called tank deodorants. A simple way of
reducing the smell is by using washing soda, which cleans and
sterilizes.
Leaking hoses,hose fittings, tanks, tank covers, etc., can also
cause a smell nuisance. So carry out a regular check of the
whole system.
For dimensions, see drawing on page 25.
Flexible Waste Water Tanks for grey water and black water

Use

Emptying
The longer waste water remains in the tank, the greater the risk
of smell. So do not leave a waste water tank full unnecessarily.
Pump the tank empty once a week, or whenever possible.
The tank can be pumped empty in two ways:
- A 'pump-out' system on the jetty is connected to the tank
cap. This will empty the tank out.
- A pump on board the ship pumps the waste water out via the
deck cap and a hose connected to it. This pump should have
a passage of at least 38 mm. diameter.
During your absence
When sinks, wash basins, showers, etc. are not used for a long
time, the water in the S-bends, fitted as a smell trap in the drain
pipes, will evaporate. This will lead to a smell nuisance. So
put plugs in all drains when the ship is not manned for a long
time.
Clean and sterilize the tank and pipes at least once a year, pref-
erably at the end of the season.
Cleaning
Grey water tank
Clean the inside of the tank with water and a good degreasing
household cleaner. Rinse the tank with clean tap water.
Black water tank
Clean the inside of the tank with water and a good toilet
cleaner, use household vinegar when there are scale deposits.
Rinse the tank with clean tap water.
Sterilizing
Sterilize the tank by filling with a solution of chlorine bleach
in water (1 : 1000). Allow this solution to circulate through the
waste water system. Remove the solution and rinse tank with
clean tap water.
