Registration Info for Temporary Services

Upon the first service, vessels will be provided an orange pump-out flag to be flown when service is requested. This flag shall be flown from a visible location aboard the vessel. Service will be provided only when the pump-out flag is properly displayed. A monthly endorsement sticker will also be placed on the vessel upon the first service. For each new month of service thereafter, a new endorsement sticker will be placed on the vessel. This sticker shall serve as documentation for compliance with the Monroe County Proof of Pumpout Ordinance.

Every effort will be made to provide your vessel with a routine, weekly pump out service if requested. However, weather, safety, or other scheduling considerations cannot guarantee that you will be provided service on a routine schedule.

Additional Pump-out Options

There are more than 30 shoreside pump-out facilities located throughout the Florida Keys.

Florida Keys No-Discharge Zone

The Florida Keys is entirely within the Florida Keys National Marine Sanctuary (FKNMS). Waters of the Florida Keys have been designated as a federal No Discharge Zone (NDZ) by the Environmental Protection Agency and FKNMS in order to help preserve the water quality of our nearshore environment and coral reef system.

Proof of Pump Ordinance Highlights

Vessels anchored or moored for more than ten consecutive days, and which are required to have a marine sanitation device in accordance with F.S. § 327.53, must provide proof of pump-out. 

Vessel owners may utilize a pump-out service that may be provided by the City of Key West, City of Marathon, Monroe County, or other authorized vessel pump-out facility or vendor. This can include locations such as public or private marinas, mobile pump-out trucks, and/or RV park dump stations. 

If a vessel owner utilizes another vessel pump out provider, the vessel owner is required to maintain documentation (ie. a receipt) and pump out logs to demonstrate the use of pump-out.   

Pumping out beyond the boundaries of the No-Discharge Zone may also be considered proof of pump-out if substantiated with sufficient GPS data and pump out logs.  

Proof of pump-out, regardless of the type of proof, must indicate that the vessel was pumped out within the last thirty (30) days.

Penalties for non-compliance are outlined in Section 26-104 of the ordinance.


The nearshore waters of Monroe County are popular for transient and local boaters, many of which liveaboard. However, many of these boaters anchor out for extended periods of time and do not boat into shore to have their marine sanitation devices properly emptied. 

In 2009, Monroe County established an internally-operated mobile vessel pump-out program in Key Largo to assist boaters. 

In 2013, Monroe County partnered with the State of Florida Department of Environmental Protection Clean Vessel Act Program to expand and contract the services to a private vendor in order to provide the services Keys-wide. The service was provided free to anchored-out vessels to ensure boaters in our many anchorages have the means to properly and legally pump out.

Since this time, the program has been a great success by preventing millions of gallons of sewage from entering the sensitive marine environment. 

As of 2019, the service had registered over 3,500 customers and regularly serviced over 700 vessels throughout Monroe County waters (both shoreside and anchored vessels). This resulted in over 2,000 pump-outs being performed each month which collected more than 280,000 gallons per year. 

The program is funded in part by state and federal funding assistance as well as through recreational vessel registration fees. The table below shows the funding history since the program's inception.
