Type III marine sanitation devices (MSDs), which are holding tanks, have the least effect on the environment. They do not discharge waste into the water but instead store it until it can be properly disposed of at designated pump-out facilities. This ensures that sewage is managed responsibly, minimizing pollution and protecting marine ecosystems.

A marine sanitation device is possibly a net or fluid of some sort that soaks up oils on the surface. Large harbors have small tugboats for this purpose that use a trapping net device to clean up spilled oil from freighters.

To prevent the discharge of untreated waste from a Type 1 or Type 2 marine sanitation device (MSD), ensure that the device is regularly inspected and maintained according to manufacturer guidelines. Always monitor and verify that the device is functioning correctly before use, and utilize the MSD only in compliance with local regulations regarding waste disposal. Additionally, ensure that the device is properly connected and that any discharge valves are securely closed when not in use. Lastly, educate all crew members on the proper operation and importance of the MSD to prevent accidental discharges.
