Grey Water Hacks: 5 Tricks For RV Life

Those of you that have been RVing for a while know the grey tank will reach capacity long before the black tank, and most likely before you deplete your potable fresh water tank as well.

To be able to extend the time you spend dry camping, you will need to learn some ways to minimize the amount of wastewater that enters your grey tank.  

1. Use a dish pan in your sink.

Purchase a dish pan that will fit in the kitchen sink of your RV. When you finish doing the dishes consider “disposing” of the dishwater in one of four ways rather than sending it down the kitchen drain to the grey tank:

  • Where legal (most everywhere), use it to water a thirsty bush just like tent camping.
  • Use it to quench the evening campfire.
  • Dump it down the toilet into the black tank.
  • Save it in a gallon milk jug and use it to flush the toilet.

 

Remember the black tank seldom fills up before the grey tank, so take advantage of the “extra” space. In addition, the soapy dishwater will help keep your black tank clean.

Be sure to use environmentally-friendly biodegradable dish soap if you will be disposing of dishwater on the ground.

2. Purchase an aerated showerhead with an on/off button.

An aerated showerhead utilizes less water than the showerhead that came with your RV, and the on/off feature will allow you to take “Navy Showers.” Less water used equals less wastewater in your grey tank.

3. Purchase a sewer cap with a hose connection.

This handy device allows you to adapt a non-potable garden hose to the 3” termination outlet on your RV and dispose of grey water in one of two ways:

  1. Where legal (not as many places as they were a few years ago) or with a rangers permission, you can slowly drain your grey water onto the ground in the boondocks. Dig a sump first, be sure to filter out small food particles with a screen to avoid attracting pests and cover when done.
  2. Route your grey water into an approved wastewater sump.

4. Spray your dishes before washing them.

Purchase a spray bottle and fill it with a mixture of dish soap, water, and a little vinegar. Spray the mixture on dirty dishes and wipe before washing which will greatly reduce the amount of water required to finish washing them.

Less water used equals less wastewater in the grey tank. Dawn dish soap is a favorite among many RVers.

5. Recycle your RV grey water.

The granddaddy of all grey water hacks is to recycle wastewater from your grey tank to flush the toilet.

This grey water hack employs a pump and filter to draw wastewater from the grey tank and uses it to rinse the toilet in place of potable water. This is the same concept as the last point in Hack #1, but a lot more convenient. Learn more about this hack here.
