Resources for Finding Free Potable Water and Dump Stations for RVs

Free RV water and dump stations are more available than you might think. Many of them are actually hiding in plain sight. From parks to gas stations, rest stops, and visitor centers. Chances are, there are free public water refill and dump stations near you. Here, you will learn how to find them and some good practices for using them.

Starting with their characteristic signs. Be on the lookout for the (usually brown) RV dump station sign or the cup of water icon. You can conveniently find these at rest stops, visitor centers, truck stops, and near main RV attractions like national parks, national forests, and state parks. Some lesser-known locations for these services are gas stations, parks, storage lots, rest stops, and even stores like Autozone and Napa. 

To plan your trip and refill stops ahead of time, use phone apps like Campedium, iOverlander, or Trucker Path. Just zoom in on the map to the area you are interested in and look for the water drop or the dump station icon. The best part of these apps is not only that they offer the exact locations but that they have plenty of recent reviews from fellow travelers. Read them through to best prepare for what to expect at your chosen site.

Where to Find Free RV Water Fill-Up Stations 

The usual set-up you’ll find in water refill stations is as simple as a free-standing water spigot. To use, simply connect your hose between the spigot and your water intake. To find an RV water fill station near you, use the apps mentioned above, or stay on the lookout for a spigot.

Best Practice for Using Free Water Fill-Up Stations

The most important part of using free water fill-up stations is to Bring Your Own Hose! There won’t usually be one available, so this is very important! And if you will be resorting to public stations regularly, we recommend getting an extra-long and high-quality one paired with a water filter.

One important thing to mention when it comes to water refilling stations is potable vs non-potable water. Potable water = safe drinking water; this is the water you want to refill your tanks with. Non-potable water is not recommended for your RV tanks, as you will be using it for things like brushing your teeth or cooking. Non-potable water is considered unsafe for human consumption.

Usually, a blue spigot signifies potable water and a brown/red spigot non-potable water. In most cases, clarifying signs will accompany the stations, but don’t hesitate to ask for clarification from employees if you are unsure. Investing in a water filtration system, whether under sink or independent, is a great idea if you plan to use these stations often.

Finding Free Dump Stations

Free RV dump stations are harder to find but still around. Just two important things to know before using public dump stations: bring your own sewage hose and clean up after yourself!

Common places with free dump stations:

Best Practice for Using Free Dump Stations

To use a free dump station, make sure the sewer opening is unlocked and in working condition before securing your drain hose. A good practice is to run water through the sewer opening before starting to dump your tanks to ensure everything works as needed.

Before you start, get familiar with the establishment. Make sure your connections are secure before draining your waste tanks. Never done it before? No problem. We have an easy video guide for you. Leaks and spills are normal, but try to contain them the best you can. Most importantly, don’t skip the final rinse. Many of the public stations you will come across will have a water hose or spigot nearby, they are provided to help clean up the area. So, no excuse not to rinse and clean up after you are done.
