The discharge of marine toilets ("black water") and of sinks and showers ("grey water") directly overboard in yacht harbours or other sheltered water is more and more restricted nowadays.
In order to overcome this problem and yet fully comply with the rules, Vetus has developed a system for temporary onboard storage of waste water.
This waste can then be discharged overboard whilst sailing in open water or, preferably, pumped into a holding tank or sewer at a convenient point ashore.
These tanks may be installed in existing craft relative simply, without the necessity to replace the marine toilet.
Owing to the special odour imperemable material used and to the thick wall construction, these Vetus waste water tanks are designed for the temporary storage of "black water" (toilet waste).
The waste water tank will need an inlet connection for each toilet, shower, washbasin etc.
A connection kit BTKIT, "no-smell" sanitary hoses and angled connectors for inlet and tank ventilation in various diamters may be ordered separately to suit your requirements.
Please note that to prevent unpleasant odours, we recommend the use of separate tanks for "black water" and "grey water" waste.
When a marine toilet is connected to the tank the use of Vetus odour tight sanitation hose is an absolute must.
Other accessories such as deck plates, extraction pipes, hoses, etc. may be ordered separately as required.
The use of a Vetus diaphragm pump is recommended to empty the tank.
This type of pump is not prone to clogging with smi-solid waste.
These Vetus tanks are made in 9 different shapes and sizes, with contents of about 42, 61, 88, 110, 137, 170, 215, 335 or 390 litres. Provided with ISO 8099 identification.
The 88, 137, 170, 215, 335 and 390 litre models are provided with baffles, as a standard construction element.
