About RV Dump Station Map

RV Dump Station Map is a free, fast directory of places to empty your RV's black and grey tanks. It currently lists 3,687 dump stations across 49 states, organized by state and town so you can find one without wading through ads or sign-ups.

Where the data comes from

We combine several open and public sources, remove duplicates (for example, a campground and its dump station listed twice), and drop private campsite hookups that aren't open to travelers:

• OpenStreetMap, the open map built by volunteers, available under the Open Database License (ODbL): most standalone dump stations, campgrounds and RV parks, and interstate exits.
• Recreation.gov (RIDB): federal campgrounds run by the Forest Service, Army Corps of Engineers, National Park Service and Bureau of Land Management, including posted dump fees.
• Truck stop chains' own public store listings (Love's, Pilot and Flying J) for which locations have an RV dump.
• The U.S. Census Bureau for town, county and state names, and OpenStreetMap Nominatim for street addresses.

Accuracy

Fees, hours and seasonal closures change, and some listings are missing details. Treat each listing as a strong lead, and call ahead before you drive out of your way. "Fee unknown" means we don't have a confirmed price, not that the station is free.

Fix or add a dump station

Use our report form to tell us about a closed station, a new fee, fresh water or a station we're missing. You can also edit OpenStreetMap directly (tag itamenity=sanitary_dump_station); your change will show up here after our next data refresh.
