Discharge of Sewage and Waste
State law prohibits the discharging of any sewage into the waters or onto the shorelines of Arizona. Use restroom facilities provided on the shore or floating restroom facilities. Consult a lake map for the locations of facilities.
If you have a vessel with installed toilet facilities, it must have an operable marine sanitation device (MSD) on board. All installed devices must be U.S. Coast Guard–certified. Vessels 65 feet or less in length may use a Type I, II, or III MSD. Vessels over 65 feet must install a Type II or III MSD.
Types of MSDs
A Type III MSD is the simplest and most common, consisting of a holding tank or portable toilet. Waste is to be discharged into a pump-out facility.
