The overboard disposal of treated effluent has proven to be a realistic alternative for many boaters interested in fewer visits to pump-out stations. With this technology you can be environmentally responsible and compliant with all but "zero discharge zone" regulations, and with a twist of the Y-valve, the holding tank can be put back into use making the vessel fully compliant.</em></p> <p><em>Federal and Local regulations determine whether treated sewage can be pumped overboard or into holding tank. Ensure holding tank is empty, prior to operating in restricted pumping areas.</em></p> <p><em>So the answer is they still need a method of prohibiting accidental discharge.</em></p><div class="item_footer"><p><small><a href="http://blogs-it.cgaux.org/mqa.php/2012/05/18/lectra-san-msd-marine-sanitation-device">Original post</a> blogged on <a href="http://b2evolution.net/">b2evolution</a>.</small></p></div> http://blogs-it.cgaux.org/mqa.php/2012/05/18/lectra-san-msd-marine-sanitation-device
