RV Dump Stations Williston, ND -- Free & Paid Sani-Dumps

Williston has several RV dump stations, with some free option available. That's a solid lineup for a city that's seen massive growth thanks to the oil boom and sits right in the heart of North Dakota's Bakken region.

You're in the northwest corner of the state, about 20 miles from Montana and an hour south of the Canadian border. This is serious oil country, which means the roads are built for heavy traffic -- good news for your rig. US-2 and US-85 intersect here, making Williston a natural stop for cross-country travelers and workers heading to the oil fields.

The dump station mix here leans heavily toward RV parks and campgrounds, which makes sense given the transient workforce and steady stream of travelers. You'll find sanitary dump stations at private parks like Prairie Acres Campground and Buffalo Trails, plus a couple of options at gas stations and truck stops. Most are designed to handle the constant flow of RVs that roll through town. The facilities are straightforward -- no frills, but they get the job done. Water fill-ups are available at most locations.

Access is easy from either highway. If you're coming from the east on US-2, you'll hit the main strip with several stations within a few miles of each other. From the south on US-85, it's a straight shot into town. Roads are wide and well-maintained year-round because of the industrial traffic.

Check the full list below for specific locations, hours, and whether you need to be a customer to dump. Some require a campground stay, others take drop-ins.

Of the several stations here, some (a portion%) are free, while a portion% charge a fee. That free option is at a city park, and it's first-come, first-served. Get there early in summer.

Paid stations run $5 to $15, with most landing around $10. RV parks typically charge $15-20 for non-guests to dump, but that often includes water fill-up and sometimes a quick rinse station. Gas station dumps are cheaper -- usually $5 to $8 -- but facilities are more basic.

If you're staying at a campground, dumping is included. Some parks offer discounted dump fees if you buy fuel or propane. There's no regional dump pass system in North Dakota, so you're paying per use unless you're a campground guest. Honestly, the free station works fine if you're not in a hurry and don't mind waiting your turn.
