4,468 RV dump stations listed by U.S. federal, state and local agencies and OpenStreetMap, plus 1,501 places where a dump station is likely but not confirmed. Pick a state to see each station and where its record comes from.
Choose a state to list its dump stations. The full map is on the campground map.
A dump station is a sewer inlet, usually a concrete pad with a hinged cap, where you empty your RV’s black (toilet) and gray (sink and shower) tanks. Most have a separate non-potable water spigot for rinsing. Pull up so your sewer outlet is on the same side as the inlet, and leave room for the next rig.
Disposable gloves, your sewer hose with its fittings, a hose support if the inlet is uphill, and a rinse hose that you never use for drinking water. Keep the rinse hose stored separately from your fresh-water hose and label it.
Connect the sewer hose to the RV first, then put the other end firmly into the inlet. Open the black tank valve first and let it drain completely. If your RV has a black tank flush, run it now with the black valve still open, following your owner’s manual, and stop the water before you close the valve. Then close the black valve and open the gray tank: the soapy gray water rinses the hose on its way out. Close the valves, lift the hose to drain it toward the inlet, rinse the pad, and cap everything before you leave.
Many dump stations are free at state parks and rest areas; others charge a few dollars, and campground stations are often for registered guests only. When a record includes access or fee information from its source we show it, but it can change — check posted signs or call ahead.
Listed A government agency or OpenStreetMap lists a dump station at this place. We show the source for every record. Being listed does not guarantee it is open, free, or open to the public.
Likely Not confirmed. Either a state rule requires a dump station at that type of place (for example some state codes require one at RV parks, usually for guests) or the record comes from a permit that suggests one. Call ahead before you plan around it.

No list is. It contains what U.S. agencies and OpenStreetMap publish. Dump stations at private businesses such as travel centers appear only when a public source lists them, and some listed stations may have closed. If you spot a mistake, OpenStreetMap is the fastest place to correct it for everyone.
