Hello, everyone. I bought a trailer recently that I use full-time that's parked in the backyard of my sisters home, and I have some concerns about the black water. I try not to use my bathroom in the trailer because I currently don't have my truck so I can't take it to dumping sites, but It's not 2/3 Full and the very close to being full. I was doing research and I found some portable Septic Holding tank that's 250 gallons. We have a septic system but it does not have hooks up, and the place that we use to empty said they will empty the trailer but it's at an expensive price since they are coming all this way to drain a trailer, so my question is ...Does anyone have any experience with portable septic holding tanks? I have provided a link below of the one I am looking at. Any advice will be great, I just don't know what else to do and I don't want it to fill up and then I have a huge mess in my hands. Thank you to all!https://www.ntotank.com/250gallon-nto-black-above-ground-septic-holding-tank-x9470922

Remember that water weighs 8.25 pounds per gallon. If your full tank is 40 gallons that's 330 pounds. NOT easy to move around a container weighing that much. And what does the proposed 250 gallon tank weigh empty? Be careful quickly pouring a large amount of water into a home septic system. It may not be able to handle that volume quickly.

Maybe I don't fully understand your solution but doesn't that just transfer your problem to the portable holding tank? How will you dump that? Remember your RV doesn't have a septic system, they are holding tanks and so is this portable one. So without dumping your blank tank in the RV or this "portable" one it will just continue to break down waste and stink to high heaven. Not sure how portable a full 250 gallon tank is - would weigh about 2,000 lbs. If you have a septic system at the house you could add a cleanout to it for less than the cost of this portable tank. For that matter you could get quite a few runs from a honey wagon for the price of a portable holding tank. Maybe I am missing it, but this doesn't really solve your problem. Seems like it creates a new problem. I think the purchase of this trailer was a bit ready, shoot, aim without considering this issue would come up.

Hose close is the Sewer/Septic Cleanout at your Sisters place?Buy a Flojet Portable Macerator Pump and a 3/4" garden hose in length needed to reach the cleanoutThen Dump/pimp your Waste tanks...black then grey into the clean out

Hello all. So I had a truck, but there's something wrong with the engine and that may take time to fix and lots of money, so that's why I can't go to a dumping ground. Theres a company we use for the septic tank that said they can come and empty my trailer, but I don't want to have to have them come out so often.The septic tank is about 30 feet away from my trailer. I just wanted to see if that for the moment if anyone had experience with these types of tanks. I usually use the restroom in the main house, but I had family members over who used my restroom in the trailer, even thought I asked for them to use the main house causing it to get full.

If you don’t mind dumping 5 gallons at a time you can buy a portable toilet and just use the bottom half to dump into. The hose fits perfectly into the valve and you just pour it into the house toilet. I use this to empty my tank when I get home. Takes a couple of trips but it’s cheap and easy.

Sonething like this

How close are you to the house?
With a macerator pump (garbage disposal for your black tank), you even run the garden hose up and into a first floor toilet. Just duct tape up the hose’s threaded end to protect the porcelain and feed the hose into and up through the the toilet’s S trap a foot or so.
Not so popular with Sis as using a septic clean out access, but still workable and can be fairly clean.
Black, then gray tanks, then flush clean water through the macerator. They have an inlet on the side.

If you're just going to dump it in the septic tank anyway, if it's a flat 30 foot run, I'd just get 30 feet of sewer hose or a macerator and avoid the portable tank completely.

30'? Just run your sewage hose to it. Or, get some 3" ABS pipe and slap it together (don't even need glue).

Keep It Simple...If a downhill run, just get a long sewer hose. If uphill, get a macerator pump
