FEMA Trailer Suggestion

If its gonna be parked at the lake and NOT moved , you will have to empty the tanks somehow ? and somewhere ?

I'm sure it has been done.............legally is the question :B

Pumping water from a river to use as showering and flushing toilet is no different then swimming in said river.

Using one waste containment holding tank is nothing new either. Wasn't that many years ago RVs just had one waste tank for grey and black waste water.

Pump with suction screen and filter on discharge supplying your 'get away' camper........just need power source
Then means of collecting/containing all waste water to be hauled away and properly dumped

ford truck guy, yes the camper will stay on the river lot and not moved unless it is going to flood. I am not worried about taking the tanks with me when I leave to empty them, just wanting something easier than carrying 2 or more tanks with me every time we come and go. Old-Biscuit, the river is actually a clear river, one of the cleanest in my area. We will only be staying up to 3 nights at a time so I was thinking just trying to filter the sand would be good enough to at least rinse off with during the summer months. I have power on the lot so that is no worry's. Just need ideas for an easy pump and filter system. My camper has a hot water heater, but I think its just plumbed to all empty out of the same spot on the camper.

Composting toilet ? There are also toilets that use electric to reduce the waste to ash , common on ferry boats , I priced one at eleven hundred dollars ten years ago .

being in arkansas lets redneck it get some plastic 55 gal drums put a hose fitting on the bottom of them use gravity feed for water

septic get a blue tote for waste and hook it up empty as needed

At our wilderness property I dug a hole twice the width of a 50 gal drum and a little bit deeper. Punched a bunch of holes in the drum with a pickaxe and put it open end down into the hole. Cut a hole in the top for a pvc pipe to connect with my sewer hose. Filled the hole with 2 inch rock up to near the top and buried the whole thing. Put in SeptoBac twice a year and it has been working for going on 17 years now. Simple and easy.

you might check with the State you live in if you can pump water from a river. In Oregon where I live, water in lakes and rivers are public property and you must apply for water rights from the State.

11point - Just guessing, but you must be somewhere close to Pocahontas (near the 11 Point River)

Install a septic tank at the camp site?
