Filling fresh water while dry camping

I use a small water pump powered by my electric drill that I can draw from a bucket or? with a short length of 5/8" hose into my normal fill fitting and filtration system.

I built a water filter so I can take water from a lake or stream and make it safe. I use a 20 gallon tub, a standard RV water pump and a 1 micron filter. I filter the water and pump it into the fresh water tank via the 12 volt RV pump. I also use a multi stage filter system for the gray water tank so I can reuse that water for watering trees etc. The final filter is activated charcoal. Everything going into the gray tank is environmentally safe. We have never had the smell problem some talk about. We only use this when dry camping when it is permissible.

Portable tank same as above, but for the pump there are a lot of options. If you have a cordless drill there are small pumps that are cheap but for very occasional service work well that just go on the drill, garden hose connections on both sides to allow connections.
Horrible Freight and others carry the little pumps.

I connect to the winterizing fitting (suction side of RV pump) and pull from 5 gallon jugs or a 60 gallon bladder. Installed an additional pump switch near the basement door side where the pump is.

When I installed dual filters and a pressure tank I also teed into the pressure side of the pump to the tank gravity fill hose so I can open a ball valve and fill the fresh tank from the jugs or bladder.

When I'm done I cap the winterizing port and stow the hose in my clean storage bag. If I get well water I bleach it. When storing jugs and bladder I bleach them first and rinse/bleach before using again if it's been awhile.

You’ll learn to watch closely for potable water and fill whenever available. RV Parky shows where water is most of the time. Ask camp hosts, they usually have water at their site, and ask other campers. Four to five gallon water jugs in the TV for when you go to town.

Thanks

I purchased a 35 gallon water tank that I keep in the bed of my pick-up (trailer camper, and truck has a shell). I fill the water tank and then I can transfer the water to the trailer using a simple, non expensive water transfer pump I purchased from Lowes. The pump is 120v AC, and this works great when we are at campsites that has electricity but no water on the site. But I also have a 400 watt inverter (battery 12v DC to 120 AC household current). I keep a lightweight extension cord in my truck. I plug in the inverter, plug in the extension cord, plug in the pump and let the water fill the trailer. Works absolutely marvelous. And yes, I use it mostly with AC power available, but have on several occasions also used it powering from the truck battery. What's so great about this set up, it's 100% portable! I can take water anywhere.
