Every fall the same question comes up from snowbirds heading south, weekenders winterizing their rigs, and drivers on late-season trips: "The dump station I always use is closed. Where do I go now?" Here's what the official sources actually say, and how to avoid pulling into a locked dump.

What closes in winter (and why)

• State rest area dump stations. Some are seasonal. Washington's DOT rest area page has a separate filter for "RV Dumping Station Closed During Winter," and it lists the dump station's status apart from the rest area's. A rest area can be open while its dump station is closed (WSDOT rest areas). Oregon's TripCheck lists six rest stops with RV sanitary dump stations and marks Clyde Holiday State Park's as "open March through November" (ODOT TripCheck).
• State park dump stations. Many follow the camping season. Wyoming's Keyhole State Park says its dump station "is seasonal" and the season "normally runs from the 1st of May to the 30th of September," weather dependent (Wyoming State Parks).
• Rinse water gets shut off first. Even where the dump stays open, the water is often turned off for freezing weather. On October 7, 2026, the City of Paynesville, Minnesota posted that "the parks and RV Dump site can still be used, but ... no water will be available" (City of Paynesville on X). Carry your own rinse water.
• Maintenance closures can happen any time of year. See our closures log for current examples on I-5 in Washington.

How to check before you drive

1. Use the state DOT's own rest area page, not last year's app review. If the state publishes a live status (Washington does), trust that over a map pin. If it publishes only a list (Oregon), call ahead. Oregon's page links to the Oregon State Parks status page to confirm current park facilities.
2. Check the park's own page or call. State park pages often post end-of-season dates and a phone number. Keyhole, for example, says "Call 307-756-3596 to check current availability."
3. Check the truck stop location page or app. Pilot Flying J lists RV dump stations among its RV services (Pilot RV Services) and Love's lists dump stations among its RV amenities (Love's), but not every location has one. Filter by location before you exit. More in our truck stop dump station guide.
4. Look at the interstate pages here. Our I-5 Washington page shows each station with a last-verified date and its official source.

Where else to dump when your usual spot is closed

These are places RVers commonly use off-season. Availability, fees and rules are set locally, so call first:

• Truck stops with RV dump stations (see above). Pilot notes Good Sam members get "Discounted Dumping Fees" at participating locations; it doesn't publish one national price (Pilot).
• Year-round private RV parks and campgrounds. Many let non-guests dump for a fee. Ask at the office. See how to book RV parks.
• Your city's wastewater treatment plant or public works yard. Some towns run a public dump site. Ask your local public works or sewer utility.
• RV dealers and service centers. If you're winterizing at a shop, ask whether they'll empty your tanks as part of the job.
• At home, only if your local rules allow it. Ask your sewer utility or septic professional first. The EPA warns that some holding tank chemicals (for example, formaldehyde-based deodorizers) can harm septic systems and pollute groundwater (EPA: Safe wastewater disposal for RV owners).

Never dump onto the ground, into the street, or into a storm drain. It's illegal in many places. For example, the City of Oakland, California says its municipal code, Alameda County regulation, and California state law "prohibit pollutant discharge to the street, gutter, or storm drain system," and that dump stations and mobile pump-outs are the legal way to dispose of RV wastewater (City of Oakland). Check your own city's rules.

Cold-weather dumping tips

• Bring your own water for rinsing, because station water is often shut off (see above).
• Dump before a hard freeze, not after. A frozen valve or hose is the worst time to find out the station is closed.
• Store your sewer hose drained. Water left in a hose can freeze and crack it.
• Winterizing? Empty and rinse the tanks first, then follow your RV manufacturer's winterizing procedure in the owner's manual. Don't guess at antifreeze amounts or bypass valve positions; they're specific to your rig.
• Wear gloves and wash up after.

FAQ

Do rest area dump stations close in winter? Some do. Washington tracks dump stations "Closed During Winter" separately, and Oregon lists at least one rest stop dump station as open March through November. Check the state DOT's page for your route.

Is the dump station open if the rest area is open? Not necessarily. Washington lists the two statuses separately, and a rest area can be open with its dump station closed.

Will there be water to rinse my hose? Don't count on it in cold months. Bring your own.

What does it cost to dump at a truck stop? The chains don't publish one national price. Ask at the location; Pilot advertises discounted dumping fees for linked Good Sam members.
