What is a Marine Sanitation Device (MSDs)?
A marine sanitation device (MSD) is “any equipment for installation on board a vessel which is designed to receive, retain, treat, or discharge sewage, and any process to treat such sewage.” Under Section 312 of the Clean Water Act (CWA), sewage discharges from vessels are controlled in part by regulating the equipment that treats or holds the sewage (marine sanitation devices).

What are the three different types of Marine Sanitation Devices (MSDs)?
Type I MSDs are flow-through devices suitable for vessels up to 65 feet in length. Coast Guard approved Type I marine sanitation devices use a combination of maceration and disinfection to treat vessel sewage. After pulverizing the solids, the effluent is exposed to disinfectants (often chlorine tablets) that reduce bacteria levels to below the established limits under the Clean Water Act. In some cases, bactericide can be generated from the saltwater using special electrodes so that no added disinfectant products are needed.
Type II MSDs are flow-through devices suitable for larger vessels. Coast Guard approved Type II marine sanitation devices are biological systems. First, sewage is aerated so that the bacteria already present in the sewage can thrive and begin to consume/break down the sewage as their food supply. As with the Type I devices, the remaining liquid waste is then treated via contact with chlorine tablets, UV disinfection, or other disinfection methods. Overall, Type II devices can achieve better treatment levels than Type I devices because of the biological component of the system, as opposed to maceration.
Type III MSDs are holding tanks that do not treat sewage onboard the vessel. A Coast Guard approved Type III devices are designed to store treated or untreated sewage effluent while preventing overboard discharge.
| Coast Guard Type I MSD | Flow-through treatment devices that commonly use maceration and disinfection for the treatment of sewage | It may be installed only on vessels less than or equal to 65 feet in length |
Must produce an effluent with:
|
| Coast Guard Type II MSD | Flow-through treatment devices that may employ biological treatment and disinfection (some Type II MSDs may use maceration and disinfection) | It may be installed on vessels of any length |
Must produce an effluent with:
|
| Coast Guard Type III MSD | Typically, a holding tank where sewage is stored until it can be discharged shore-side or at sea (beyond three miles from shore) | It may be installed on vessels of any length | No performance standard; must “be designed to prevent the overboard discharge of treated sewage or untreated sewage or any waste derived from sewage.” 33 CFR 159.53(c) (PDF)(2 pp, 163 K)). |
