Safe Way to Dump Black Water While Boondocked

I have a piece of property we plan to "boondock" at this summer for a couple months. It will have water and electric (so not really boondocking) but we don't have sewer. Does anyone know of any eco-conscience and safe way to dump the black tank on site? There is a small stream nearby and I wouldn't want to dump directly there but if would help dilute things down...

I should add that the location is out in the country and the next closet neighbor is a good 1/2 mile away.

I would run a garden hose to the nearest shrub or bush that needs water. I would avoid the stream. if that isn't possible, you could dig a deep hole, fill it with rock and top it off with dirt. This would loosely be classified as a dry well. Not unlike a drain field in a septic system.

Probably illegal but dig a hole and bury a fifty gallon barrel with holes cut in the bottom and bottom sides. Fill the bottom of the hole with gravel and place the barrel on top. Make sure the barrel is not noticeable from a distance. Cut a three inch hole in the top of the barrel and dump your black tank there. Must be far away from the creek and the well, so you may need to use a blue boy. Run a hose far out into a field and discard gray water that way as to not fill the barrel. This works, don't ask me how I know. Oh yes, fill the barrel with dirt when you leave, u less you want to use it again at a later date. Be sure this is okay with the landowner. Jim

When I was a kid we had a mobile home we used during the summer at the beach. It was permanently installed & my dad used the above mentioned 55 gallon barrel trick to create a septic system. I'm pretty sure it was installed as described by avionstream and it worked for over 10 years for us. He was always putting something down the drain to treat the waste, most likely today a product like Ridex thats used in septic systems would work. Our toilet was the normal flush type but I don's see why dumping a holding tank would make any difference as long as the barrel has time to drain between dumps.

I built a system, which is near complete that consists of a macerator pump which pumps up into a blue tote that is mounted on a cargo carrier on the front of my truck. I plan to offload black and grey then drive to the dump station. Obviously you would need a dump station nearby, there is an app called RV Dumps or something like that which shows the dump locations. Some of them are free municipal plants.

I would not dump raw blackwater on the ground or even in a hole. I would dump grey, but I would limit soaps and toxins. Even that however, is illegal around here.

I don't know of any state where it would be legal to dump black water tank on the ground or bushes. It will stink. Dig a small cess-pool with block liner and a lid.

My wifes grandmother describes her early life bathroom at such:

It was a building, made of wood, the bottom of the walls didn't meet the ground, it had a seat inside and you just poo'd through it. Chickens on site and other animals would move it around.

This is interesting: How to Construct a Small Septic System (with Pictures) - wikiHow

I personally would see no problem running the waste on your land, people did this for centuries and it was never a problem, course with todays population, if everyone did it, it would be a problem, for one or two people to do it - I wouldn't have an issue with it.

Please take some of the advice here with a grain of salt. Do it properly. Check with other locals even the county officials and see what is exceptable in the area.

Do you know what a learning experience is? A learning experience is one of those things that says "You know that thing that you just did? Don't do that."

My family have a small cabin on 18 acres up in the mountains. The cabin currently has no services but electricity is now getting close. Black waste became a problem soon after we built it in the late 70's. We used a standard cement holding tank and put in one leach line about 50 feet long. We also put in a cistern above the cabin with a water collection cistern below the cabin where we catch rainwater. We then use a little Honda pump that we transfer rainwater to the upper cistern. We have a RV type China Bowl toilet in the bathroom that dumps into a 3" drain pipe to the holding tank. We have been using this system since the late 70's and have not yet had to pump the tank out. We did the whole install with shovels and pick axes

I bought a hand auger many years ago at a farm hardware store - it makes a hole much easier and deeper than a clam shell hole digger.
Now that I have a AS - I throw the auger in the back of the truck when I think I'm going to be in a place without sewer (most of the time).
I dig (drill) a hole when I arrive, place a round plywood cover (bought at Home Depot) with a 3" hole I drilled in the center over it, place my tank drain hose in it and cover it with dirt.
This works great when the soil is porous - not so good when the soil is hard clay and rocks.
When I leave I just refill it with dirt -
Easy and cheap.

black tank

As said above I would create a"septic tank" with a drum/barrel and have a short perforated drain line running out of it for 10-30 ft depending how porous your soil around there is.
I had a country property with a proper septic tank and 100ft of 3" perforated drain pipe out of it (full time house with grey and black water going into it).... when we developed the property after several years, and dug up the system for sewers we found that in our soil conditions only the first 10-15ft of pipe had ever seen liquid!....the rest of the pipe was still like new! Use biodegradable products and you'll be fine.

Buy one if those blue portable waste tanks for your black water and take it to nearest dump station. Direct your gray water to trees that need a drink and ONLY use plant-based soaps and cleaners like Seventh Generation, etc.
