Best RV Portable Waste Tanks For Black Water (2022)

Anyone who has fallen in love with the freedom that comes from traveling the open roads in an RV likely has complained at one point and time about having to empty the holding tank.

The holding tank is where all the water that is used in the RV -including what gets flushed- is collected and stored.

When the tank gets full, the contents need to be dumped, so there is room in the tank for the next time you wash dishes, take a shower, or flush the toilet.

The holding tank on most RVs has two different sides- black and greywater.

Blackwater is what wastewater from the toilet is referred to, whereas greywater is wastewater from the shower and sink.

There are two ways to empty the holding tank.

The first is to drive the RV to a designated dump site where you can hook up and drain the holding tanks.

The second is to empty the holding tank before it gets full and uses a portable waste tank to carry the water to the dumping station. For many RV enthusiasts, the portable waste tank is the preferred way to deal with things.

Why You Need A Portable Waste Tank

If you are new to the joys of RV life and travel, you may be wondering why you would need to bother with buying a portable dump tank. After all, your campground has a dump station on-site, and you can usually find RV access locations fairly quickly.

But any seasoned RVer will tell you that an excellent portable waste tank can be worth its weight in gold.

There are a number of key reasons why you should invest in one before you head out for your first camping trip in your RV:

dumping the RV tank

Freedom of Movement

One of the primary, as well as most obvious, benefits of having a portable waste tank is that it can let you camp longer because you don’t have to move sites or pack up whenever your tank gets full.

It can also be very useful if you’re not parked near a dump station, so you don’t have to drive your RV a long way to get the holding tank emptied.

When you camp in the same spot for weeks at a time, the ability to empty the holding tank and easily transport it to the dump station, all without having to pack up and move the entire RV off your campsite, is a major benefit you will greatly appreciate.

You can camp much easier where and for however long you want and be in more control over your movement and campground rotation. Doing it once without a portable tank is usually all it takes for beginners to learn how much freedom they really can provide.


Another benefit of these small water tanks is right in their name- they are portable. These water holding tanks are fitted with durable wheels and handle to make them easy to push or pull as needed.

They are easily be maneuvered under your RV for filling and can also be pulled to the dump station much easier than trying to move the entire RV. The portability is what makes them so popular and is one of the best benefits you can gain from having on with you on any RV trip that you take.

Even if you do not think you will be camping long enough to need one, it is always best to have one on hand. Better safe than sorry!

They are compact and easy to carry with you and can easily be stored on the campsite so they won’t be in the way or be a bother when they are not being used.

Health Benefits

You can also benefit by ensuring your camping experience doe not make yourself, your family, or other campers sick. There are strict rules at all campgrounds about how to hook up and dump wastewater while camping on their grounds.

A portable waste water tank makes it easy to keep this dirty water contained. Rather than leaking it all over the campsite by letting your tank get too full, you can empty it regularly to ensure it does not contaminate any of the camping areas and that the water is disposed of safely.

Being exposed to water contaminated with human waste is a significant health hazard, and knowing how to correctly use a portable waste tank can help ensure your camping experience is a safe and healthy, and happy one. It is a very small and simple thing that can have a truly enormous impact.


The final reason you should consider one of these dump tanks on wheels is that you basically are required to have one or some other alternative. As we have already established, you need to be able to safely empty your tanks to avoid contaminating the campsite.

It would be best if you also had something easy to use, so you do it as often as you need to. Violating regulations concerning safe and proper wastewater disposal is not only a guaranteed way to get kicked out of a campground, but it could also land you in serious legal trouble and can result in serious fines and other penalties.

There are many strict regulations in place to help keep everyone safe while camping in their RVs. And the use of a portable waste tank is pretty much inferred to be necessary and is something most campers use to help them easily comply with all regulations and requirements.

Getting The Right Size

Now that we understand how important and beneficial these portable dump tanks can be, the next obvious question is something along the lines of how big should the tank be?

There really is no right or wrong answer to this question as a large part of the decision for how big is big enough depends on your personal wants, needs, and situation.

Here are some general points to keep in mind as you consider the size you will need for your portable waste water tank:


  • Ideal for singles or couple camping trips
  • Best for short, long weekend RV outings
  • Used only for blackwater and not greywater
  • Usually holds around 10 gallons or less


  • Meant for longer trips that use little water
  • Suitable for singles and couples or small families
  • Can handle black and grey water separately
  • Usually holds about 15-20 gallons or so


  • Perfect for larger families that use more water
  • Accommodates longer camping trips
  • Allows for less frequent dumping of tanks
  • Usually holds somewhere around 25 or more gallons

Extra Large

  • Meant for longer camping trips and traveling
  • Sufficient for larger families with high water use
  • Can handle partial dumps of both grey and black tanks
  • Usually holds more than 30 gallons

Final Thoughts

Two, it is a versatile and vital part of your gear and can help you have a fun, safe, and enjoying camping trip. Three, there are many options available to choose from, so finding the waste tank that is right for you should be no trouble at all.

  1. We purchased a VINGLI waste tank to empty our travel trailer’s grey tank when we are not near “hookups”. The quality of the construction is excellent, with giant wheels for easy movement, and the price is less than half of the other brands we looked at. This makes transport and filling easy.

  2. We purchased an RV Portable Waste Tank for home use when we needed to clean out our septic system. This is one of the smoothest rolling tote buckets I’ve ever used. I like its 3-inch conventional drain valve because it makes the tank easier to use and more reliable. I don’t have to worry about lifting the jar to empty it. If you’re going on a long road trip, I recommend choosing a 42-gallon tank capacity. I’ve never had that problem with the Barker 42 Gallon Tote Tank, and I’ve been using the same model for over 5 years now.
