What must a type III Marine sanitation device have one boating on in land waters?

A Type III Marine Sanitation Device (MSD) must have a holding tank that temporarily stores wastewater and prevents it from being discharged into navigable waters. It is designed to retain sewage until it can be properly disposed of at a designated pump-out facility. This type of device is essential for compliance with regulations aimed at protecting water quality in inland waters. Proper maintenance and regular pump-outs are required to ensure it functions effectively.
