A dump station is a dedicated connection where you empty your RV’s black (toilet) and gray (sink/shower) wastewater tanks into a sewer system. You need one, because holding tanks have a limit and no hookup site means you must find one before both fill. Knowing where they are and how to use them is a basic renter skill.

Where to Find a Dump Station
| Location | Typical cost | Notes |
|---|---|---|
| Campgrounds (yours or nearby) | Free–$15 | Often free for registered campers |
| Travel centers (Pilot, Flying J, Love’s) | $5–$15 | Many list it on their app; Love’s has a filter |
| Truck stops and TA/Petro | $10–$20 | Call ahead; not all have one |
| Gas stations / rest areas | Free–$10 | Common in rural areas; ask inside |
| RV dealerships | Free–$15 | Friendly if you rented from them |
| Municipal / city sites | Free–$10 | Some towns offer a public station |
| BLM / national forest | Free | At developed recreation areas |
Apps and directories: Sanidumps, Campendium, RV Dump Sites (rVDumpsites.net), and state tourism pages. Save two options before you leave, since a station can be closed for repair.
How to Dump (Step by Step)
- Put on gloves. Keep the sewer hose and a tank rinse handle clear of your fresh-water hose.
- Pull up so the outlet is within hose reach of the dump inlet.
- Connect the sewer hose to your RV’s waste outlet, then to the station’s fixed pipe or a threaded fitting.
- Dump the black tank first, then the gray tank — gray water rinses the hose of black residue.
- Close the black valve, disconnect, and rinse the hose. Use the station’s non-potable water (never your drinking hose) to flush if a rinse connection exists.
- Rinse the black tank with a tank flush if equipped, or add a couple gallons and dump again.
- Cap everything, stow the hose in its own sealed compartment, and wash your hands.
Never leave the black tank valve open at a full hookup; let it fill so solids stay covered and rinse out on dump. Dump when it is about two-thirds full.
Legal Rules
Dumping RV waste anywhere but an approved station is illegal in every state and carries fines plus cleanup liability. That includes storm drains, vault toilets, and the ground. The same goes for gray water in many areas — dispose of it at a dump station, not on the dirt.
Rental Return Conditions
Some rental agreements require tanks emptied and the fresh tank refilled on return, or they charge a dumping fee (often $50–$100). Ask at pickup what the return condition is, and plan a station stop on the way back. Our how often to dump guide covers timing for renters.
