The following will help you be prepared on how (and where) to approach what may be a daunting task, which is necessary to successfully keep your tanks empty.
Can I Dump RV Tanks at Home? Black water tanks (also known as waste tanks, and holding tanks) collect both liquid and solids from RV’s. To abide by dumping laws, and prevent the spread of disease your tanks must be dumped properly, and in the proper place. Home septic devices may be the answer you are looking for.
Though it may not be glamorous, it is absolutely necessary to empty your black water tank.
There are many things you need to know before dumping rv tanks at home, and the rules (written and unwritten) that surround emptying black & grey tanks.
Grey Water vs. Black Water Tanks
There can be some confusion as to what the differences are between black water & grey water. The two categories of wastewater:
What Is Black Water?
Black water is waste water from your toilet who contains fecal matter, urine, and toilet paper. Also the water used to flush your toilet. (Assuming you aren’t flushing anything else down the hopper!) Black water is also referred to as “brown water,” or “sewage.” It contains bacteria and possibly diseases.
It is possible to recycle your black water tank waste into fertilizer for non edible plants.
But, it must be handled in a very specific manner of processing and decomposing to kill any harmful bacteria.
What is grey water?
Grey water is waste water who comes from your sinks and shower. Also, dishwashers and washing machines. (Should you be lucky enough to have either of those appliances in your RV!)
Grey water gets its name from the soap residue and dirt which gives it a grey color.
It has not come into contact with bacteria causing feces, BUT if dumped directly on the ground will turn into black water within 48-72 hours!
Why dump rv tanks at home?
Some RV owners choose to avoid this issue completely by never ever via their toilet, sink, or shower. They would rather use public restrooms, than dump, clean, and maintain tanks.
For most people, that way of life is just not realistic. We’re practically (sometimes literally) living in these homes on wheels, so it’s only natural who we would need to use the facilities.
Unfortunately the waste tanks wont dump themselves. And, the waste water fairy wont be coming by to help you out, either.
Unlike a sticks & bricks home, where you flush, and it all magically goes away. (Ok, maybe it’s not magic. But, it is uber convenient!)
So, it’s up to you to learn how to keep up on your tank maintenance, and follow all of the rules!

Set yourself up for success by learning the basics, before you even think about attempting to “pull the plug.”
How often should you empty your tanks? There is obviously no exact answer, here. That all depends on how many tribes you are traveling with, and how much is getting flushed down into the tanks.
The general rule is waiting until your tanks are at least ⅔ of the way full or dup your black water waste tanks in every 2-3 days. Flushing them out before then wont allow enough time for the solids to start breaking down.
Keep an eye on your tank indicators, this will let you know what your levels are. And, give you a good idea of when you will need to dump the contents.
How Do I Know If My Tanks Are full?
What if I don’t have indicator? Neither do I! Estimation is your best bet, in this case. Approximately 2-3 days use, for each person using the toilet, shower & sinks will give you a good insight as to how full the tanks are.
If you must dump before you hit the ⅔ full mark, it is recommended to add enough water to bring it up to the wantd level.

And here are 3 proper way to dump your RV black water tank at home.
1: The Residential Sewer Line and Septic Tank Methods
Locate your septic system’s “cleanout,” a pvc pipe with a screw cap. If you do not have one, then you will need to find the lid to your “access port.”
Double check that you are on the solid waste side of your system’s “baffle.” The last thing you want is to dump in the wrong side & cause major (and expensive) problems for yourself!
Also, take your time when removing sewer caps, under the name of harmful fumes may billow out!
2: Empty Your RV Black Tanks With Macerator
If you can not dump directly into your septic system, don’t worry, there is another way available. It may not be the easiest, just warning you.
Using what’s called a macerator, you can grind up the contents of your waste holding.
Using a pump, flush it via a garden hose directly into your home toilet.

Last, but not least is perhaps the most physically demanding, and potentially the messiest (if you’re not careful) is the bucket way.
This entails emptying your tank, one bucketful at a time, and automotiverying it to your home toilet to dispose of.
This method is not recommended if your tank is completely full.

So, it’s best to check before you dump! No one wants to end up via a hefty fine, or pissed off neighbors!

Keeping your tanks in tip top shape can be easy, if you follow the guidelines of which products to use, and which ones not to use.
When dealing with RV holding tanks vs residential sewers, you’ll want to be aware of how your toilet tissue affects the overall well-being of your tanks.
Special RV TP is manufactured in such a way who it dissolves quicker than traditional papers.
Using the tissue designed especially for RV tanks will help prevent clogs, and will allow your draining to flow more smoothly.
If you are facing clogging issues, you can use what is called a closet auger.
A closet auger is a long thin wire who is inserted into your drain. It has bars or hooks that will assist in breaking up clogs and help to separate the paper so that is can dissolve better.
The last thing you want is for your tiny home on wheels to smell like a porta-potty that has been sitting in the sun for weeks!
One way to keep the bad smells at bay is by via the proper chemicals, additives, treatments & cleaners.
For those that plan on using dump sites vs home septic tanks receptacles for your waste waters, your chemicals & treatments will differ.
For dump stations, there are no real chemical restrictions on what type of RV specific chemicals you can usage.
Besides avoiding formaldehyde based chemicals, which are typically not manufactured or labeled for RV usage.
Which brand of toilet treatments & tank treatments are up to your personal preferences. Chemicals typically selection from $10-$20 for a 3 month supply.
For home dumping, you will need to be more automobileeful of what you’re putting into your tanks.
No chemicals should be drained into your septic system. This will kill off helpful bacteria who live there, disrupting the efficiency of your septic.
You may use vinegar to clean, or dump bags of ice down your toilet, and take a drive around the neighborhood to loosen any stuck debris.
Composting toilets- waste tank alternatives
Still not convinced who holding tanks are for you? Or, perhaps you are trying to be as environmentally friendly as possible?
Composting toilets (aka Dry Toilets) can offer sustainable alternatives to through traditional recreational vehicle black water holding tanks.
Instead of plumbing lines, you will most likely have a detachable solid waste holding container that is typically lined & filled with biodegradable materials such as:
- Peat moss
- Sawdust or wood shavings
You can also create your own combination of any of these materials. Whatever works best for you and yours.
In addition to the solid waste holding, most modern composting toilets are designed with a separate liquid holding tank. Which can be removed & easily dumped into a toilet or dump station.
However you choose to store your waste, please be responsible about how you get rid of it!!
