Make water last longer when boondocking

Hi, Bob,
I find that I run out of water too quickly when boondocking. How can I either carry more water or conserve better? —Mike P.

Hey, Mike,

Coyote Camping near Lake Havasu, Arizona

There are two main ways to make your water last longer when boondocking. The first is to learn how to conserve your water usage, like taking “Navy” showers, not letting the water run when brushing teeth or washing dishes (turn on and off as needed), and collecting the water you run while waiting for it to get hot to use for rinsing dishes, cooking spaghetti, etc.

The second is to carry extra water in portable containers. Collapsible 5- gallon containers and Jerry jugs are the most common way. As your water tank level drops, pour the extra water into the outside water fill using a funnel to reduce spillage. Carry the empty jugs with you when you drive for supplies or sightseeing and refill them.

Installed an electric solenoid with a wall switch to route the cold water on the hot water side of the galley sink back to the fresh water tank. It’s not much, as we have a smaller camper, but in a motorhome it could mean a lot over a couple of days.

When it rains, I capture the water off my roof gutter drain spout and or from awning into a plastic bucket. Then I use an auxiliary water pump hooked to a filter and pump the water from the bucket and into my water tank.
This bucket method also works at state parks that don’t have water near RVs.


Good additions Robbie. Thanks.


Two more: Use collected shower water to flush the toilet. Rinse your dishes in a dish pan. Use paper towels to wipe off dishes and pots before soaping.
