Holding tank system – a clean and easy solution to fit every boat

Tighter laws against blackwater discharge! Clean water – a joint commitment
Boats contribute a very small volume of the total pollution entering our waterways. But discharge of sewage leads to visual pollution and takes the fun out of boating and time on the beach. It also creates local problems if discharged near swimming beaches, shellfish beds, coral reefs and other eco-sensitive waters.

Our role in this commitment is to provide on board sanitation equipment that is trouble-free and reliable. Join us in making a “clean water” commitment.

 

Examples of important steps on a national level:
Netherlands Netherlands
From 1st of January 2009, release of black water from any type of recreational craft is prohibited. All existing yachts with toilets must be equipped with holding tanks of adequate capacity as of January 1st 2009.
United United Kingdom
Direct discharge of sewage into inland waters is prohibited. Codes of Best Practice are strongly encouraged.
France France
Recreational boats equipped with toilets and built after January 1st 2008 which enter maritime or inland ports must be equipped with an installation that permits either to store toilet water or treat it.
Spain Spain
All vessels built per May 2004 or later must have a holding tank installed.

Baltic Sea
The Helsinki Convention for the protection of the Baltic Sea (HELCOM) recommends installation of toilet retention systems on all ships. The Recommendation must be taken up by national authorities.
