Typically, managing gray water is the main challenge for most RVers when dry camping for extended periods. Most RVers generate way more gray water than black water and will fill up the tank by days or even weeks ahead of the black tank. Follow these tips to help limit the amount of gray water you generate and the amount that enters your gray tank.
1. Use paper plates and compostable disposable silverware that won’t need to be washed.
2. Cook meals ahead of time to reduce the amount or water used during meal prep and washing pots, pans, and utensils afterward.
3. Use paper towels or the paper napkin used during your meal to wipe debris from your plates before washing.
4. Use less dish soap and you won’t have to run as much water down the sink drain to rinse them. Not only do the above tips save gray water going down the drain to your gray tank, but also conserve precious fresh water.
5. Wash your dirty dishes in a dishpan that fits in your kitchen sink. Use the captured dish water to:
- Water a thirsty bush in the boondocks where it is legal to do so. Know the “Dispersed Camping” rules for where you plan to camp. You can typically do an online search using the name of the land agency where you plan to boondock along with the words “dispersed camping.” For example, if you search “Willamette National Forest Dispersed Camping” you will end up on a webpage showing the rules for dispersed camping in the Willamette National Forest and rules stating you may dispose waste water at least 100 feet from any water source. Beware that different governmental agencies sometimes have different definitions of “gray water,” “dish water,” and “waste water” than RVers. If in doubt of what you can or can’t do, call the land agency. Even when legal, please be discrete and don’t make a mess when disposing of waste water.
- Take advantage of the extra space in your black tank and pour it down the toilet. The soapy water will help keep your holding tank probes clean and the extra liquid will help keep solid waste covered, meaning you won’t need to use as much water when flushing.
- Pour it into a one-gallon milk jug and use it to flush the toilet in place of water from your fresh water tank.
Another option, if you’re tow vehicle is a truck, is to carry a large waste tote & have a macerator in the rv, either portable or permanently attached. That allows you to pump grey or black water up into the truck & take it any distance to dispose of it. I carry a 35 gal waste tote in my truck & have a macerator that increases my grey water capacity from 70 gal. to 105 gal. Add a 90 gal vinyl fresh water bladder & we can boondock indefinitely without ever having to move the rv.
Propane?
How about an outdoor hand washing station? Use 2 tubs; one with soapy water and another with clean water. When either water tub gets too ‘dirty’, add some soap to the ‘clean’ water tub and empty the soapy water tub. Refill with clean water. Repeat. And you’ll need an old towel too.
Good article! But don’t clean fish near the RV — it attracts bears! Also, for faster rinsing of the dishes, use an easy rinse soap, like Dr. Bronner, in a diluted solution.
good tips, all of them. I use what I call “utility cloths” that I made from colorful old dishcloths or cheap cloth napkins that are easy to spot. You can use them to wipe grease from pans, wipe up spills on floor, wrap washed vegetables to keep fresh… you will discover a lot of uses. Yeah, you have to wash them, but you save a LOT of paper towels.
I think that you are advocating too much use of disposable paper products that will end up in a landfill. Far better to rinse dishes in a dish pan and dump out the dishpan. Water a tree with it. Also, the “navy bath” is an excellent way! However, go one step further. Get a high quality, made for the body, microfiber. With it, you can wash without soap so rinsing is even easier. Sorry, no suggestions for replacing shampoo yet! Lol….
Dawn dish detergent….biodegradable & and works on animals too.
As suggested by Ken use 2 containers of water, soap and clear, and use cloth not paper it just adds to landfill.
We keep a spray bottle by the sink with a solution of Dawn, water and vinegar. We spray down our dishes with this solution, wipe them clean, then just dribble water from the sink to rinse them. (Catching the water in a dishpan of course, and disposing of it outdoors). This saves on fresh water as well as keeps the gray tank from filling as quickly.
Any particular ratio of ingredients of dawn, water and vinegar?
