RV Dump Stations on Road Trips: A Look by Region

On a long trip, the dump station question comes up every few days. How easy it is to find one depends a lot on where you're driving. This is a region-by-region look at what Dumpmapper's RV dump & water layer lists today, based on the 3,663 RV listings in our data. Coverage reflects what public data sources map, not how many stations really exist, so thin areas are a cue to call ahead rather than proof there's nothing there.

Listings by region

The top states by listings are California (340), Washington (226) and Texas (189). Remember that these counts reflect how well each state is mapped in open data.

The West

The West has 1,385 RV listings on the map across 13 states, led by California (340), Washington (226) and Utah (155). Highway agencies help: Washington's DOT rest area list shows which rest areas have an RV dumping station and whether it's currently open or closed. Oregon's TripCheck publishes a list of rest areas with RV sanitary dump stations, for example Charles Reynolds on I-84 about 9 miles east of La Grande (eastbound side) and Clyde Holiday State Park on US 26, whose dump station is open March through November. Wyoming's DOT lists seven rest areas and information centers with RV dump stations, including Cheyenne, Chugwater, Dwyer Junction, Orin Junction and Sundance.

Dump stations at federal campgrounds may be for campers only or charge a fee, so check before you rely on one.

The Midwest and Plains

The Midwest has 1,004 RV listings on the map across 12 states, led by Michigan (187), Minnesota (152) and Wisconsin (112). Seasonal closures are rarely tagged in open data, so call ahead in late fall and early spring. Search your next overnight stop, then look along your route rather than only at the closest pin.

The South

The South has 950 RV listings on the map across 16 states, led by Texas (189), Florida (108) and Tennessee (86). Florida law requires RV liquid waste to go into an approved sewerage system, so plan on a listed station rather than improvising.

The Northeast

The Northeast has 324 RV listings on the map across 9 states, led by Pennsylvania (167), New York (58) and Maine (20). With fewer mapped stations, it pays to ask the campground you're heading to whether non-guests can dump, or to dump at your overnight stop before you leave.

Common questions

Which states have the most RV dump stations on Dumpmapper?

At launch the most listings are in California (340), Washington (226) and Texas (189).

Do highway rest areas have RV dump stations?

Some do. Washington, Oregon and Wyoming DOTs publish lists of rest areas with RV dump stations, and Washington shows whether each is open.

Why does my state show only a few listings?

The layer uses public data, and some states are mapped less thoroughly. Many campground stations aren't tagged yet. You can suggest missing ones.

Can I see RV dump stations for just one state?

Yes. The RV dump stations by state page links to a page for each state with a map and county list.

Planning dump stops on a long drive

1. Before you leave, open the RV layer and search each overnight stop. Note the nearest two stations, in case one is closed.
2. Check each listing's fee and access notes. Customers-only and campers-only stations are common.
3. Look for seasonal notes, and call ahead in shoulder seasons.
4. Dump when you have the chance, not when you're forced to. The City of Springfield, Oregon suggests dumping the black tank once it's more than half full so it drains properly.
5. Read our tank dumping guide before your first stop.
