A Type 2 marine sanitation device, also known as an MSD, is a holding tank that is installed on a boat in order to collect sewage and wastewater. The waste is then pumped out of the holding tank and into a septic system or sewerage treatment plant.
Type 2 MSDs are required by law in many countries in order to prevent pollution of waterways from boats. They are also important for public health, as they help to prevent the spread of disease-causing bacteria and viruses.
There are two types of Type 2 MSDs: self-contained units and central systems. Self-contained units have their own pumps and tanks, while central systems connect multiple boats to a single pumpout station.
Most Type 2 MSDs use chemicals to break down waste and prevent odors. These chemicals can be harmful to the environment if they are not used properly, so it is important to follow the manufacturer’s instructions carefully.
