    What you must do in a no discharge zone is to be certain that the “Y” valve is secured in the closed position.

    There are certain rules that guide discharge of sewage and waste while on a vessel. Anyone that uses the boat might want to use the onboard facilities.

    Further Explanation

    The main concern of your sewage is actually not the urine but the feces, as it contains pathogens, bacteria and nutrients. To ensure proper discharge of sewage on boat, federal regulations were put in place in order to keep untreated sewage out of the coastal and inland waters, so that individuals don’t have to consume it.

    It is illegal for anyone to discharge untreated or treated sewage into waters. All recreational vessels must have a toilet facilities and operable marine sanitation device on board. Also, the device must be sealed to prevent waste discharge into water.n

    However, there are three types of marine sanitation device. The type I and II MSDs are mostly found on the large vessels and before waste can be discharged, it must be treated with chemicals in order to kill the bacteria.

    The type I and II MSDs with “Y” valves used in directing the waste overboard must be properly secured and the valve must be closed.

    The Type III MSDs doesn’t provide any treatment; however, collected waste taken should be disposed properly. It can be disposed of pump-out or in a dump station.n



    • no discharge zone
    • Y valve
    • vessels
