A sani-dump is a public-access facility for emptying RV black-water and grey-water tanks. The term is most common in Canada; the equivalent is 'dump station' in the US and 'dump point' in Australia.

Sani-Dump Near You

Q: How do you actually use one?

Pull up so your sewer outlet is over the drain. Connect the sewer hose to your RV first, then to the drain. Black tank first, then grey. Backflush if there's a rinse hose. Treat and refill with a small amount of fresh water before driving.

Q: What if I'm in the US side of the border?

This page lists every verified sani-dump within about 80 km of your location — provincial-park dumps, municipal facilities, commercial dumps, and campgrounds that accept outside dumpers. Allow location and we'll show what's nearby; the manual search by town or postal code still works if you decline.

The kinds of sani-dumps you'll find

Provincial-park sani-dumps. Free or low-fee dumps at Parks Canada and provincial-park campgrounds. Most are seasonal (mid-May through Thanksgiving). Ontario, Quebec, BC, and Alberta have especially well-developed networks.
Municipal sani-dumps. Town and city-operated facilities, often beside an arena or works yard. Usually free or token-fee, often seasonal in colder regions.
Commercial truck-stop sani-dumps. Petro-Canada, Pioneer, Husky/Cenovus, and some Canadian Tire locations have sani-dumps. Pay CA$10-$20 typically, year-round availability, easy highway access.
Campground sani-dumps. Free for guests, usually CA$5-$15 for non-guests. KOA and Good Sam parks are reliable; smaller independents may restrict outside dumpers in peak season.

What to bring

Sewer hose, 15-20 ft.Drain positioning varies; longer is better than shorter.
Clear elbow / 90° fitting.Lets you see when the tank is empty.
Disposable nitrile gloves.Every dump, every time.
A dedicated rinse hose.Never the drinking-water hose. Black or white, not green.
A hose adapter kit.Threads aren't standardized; a small kit covers most stations.
Tank treatment / digester.Drop one in after dumping so the tank is ready for the next trip.

Winter sani-dump strategy

Most provincial-park and municipal sani-dumps in Canada close from late October through April or May. If you're snowbird-bound or winter-camping:

Plan around commercial truck-stop sani-dumps along your route.
Some larger Canadian Tire and Petro-Canada locations heat-trace their lines and stay open year-round.
Full-service RV parks with sewered sites are the most reliable; many remain open in southern BC and parts of southern Ontario.

Cross-border RVing

Sani-dump networks don't stop at the border. The underlying database covers both sides, so a search from southern Ontario will surface northern New York and Michigan facilities; a BC search picks up Washington State sani-dumps. Pricing flips between currencies in the listing; the conventions (paid vs. free, RV park vs. truck stop) map cleanly across.

Frequently asked questions

What is a sani-dump?

A sani-dump (sanitary dump station) is a public-access facility for emptying RV black-water and grey-water tanks. The term is used most across Canada — particularly in Quebec, Ontario, and the Prairies. In the US the same facilities are called dump stations or sani-stations; in Australia they're dump points. All refer to the same thing: a drain, usually a rinse hose, and somewhere to dispose of cassette waste.

Are sani-dumps free in Canada?

Many are. Free sani-dumps are common at provincial parks, municipal recreation areas, and a number of Canadian Tire and truck-stop locations. Paid sani-dumps typically run CA$5-$15 and often include potable water for refilling fresh tanks. Walmart Canada parking lots are not reliable overnight dump locations the way US Walmarts sometimes are — check the specific store first.

Can I use a sani-dump at a campground if I'm not staying?

Most Canadian campgrounds let outside dumpers use the sani-dump for a small fee — typically CA$5-$15. Provincial-park campgrounds vary; some restrict dumping to overnight guests. Call ahead in peak season.

How do you actually use one?

Pull up so your sewer outlet is over the drain. Glove up. Connect the sewer hose to your RV first, then to the drain. Open the black-tank valve and wait until flow stops. Close, then open grey — the grey water rinses the hose on its way out. Backflush if there's a rinse hose at the station. Treat and refill your tanks with a small amount of fresh water before driving.

Are sani-dumps open in winter?

Most provincial-park and municipal sani-dumps close from mid-October through April-May to prevent freeze damage. Reliable winter options in cold-climate Canada are commercial truck-stop sani-dumps, some larger Canadian Tire locations, and full-service RV parks that heat-trace their lines. Reviews flag closures faster than the official listing metadata.

What if I'm in the US side of the border?

Try RV dump stations near me instead — same listings, US terminology. Cross-border travel is common in BC/WA, ON/NY, and QC/VT, so the underlying database covers both sides.
