Every RVer who enjoys dry camping understands the tricky nature of balancing the amount of fresh and grey water that gets put into holding tanks on a camping trip. Being forced to make a trip to the dump station and replenish fresh water supplies is an annoyance that we try to avoid but sometimes even the most conservative water usage can’t prevent this kind of disruption.
Thanks to a RV grey water recycling system developed by Greg Corwin, founder of Chicago-based USI RV, now we can all spend more time camping and less time dumping. Here’s how his grey water recycling system works:
Corwin has created the Extend Your Stay Tank Saver Kit, a DIY grey water recycling system for RVs of all sizes that uses a secondary water pump to move used kitchen and bathing water out of your grey water holding tank, through a filtration system and finally into your toilet for flushing water. For those times when you’re enjoying the convenience of full-hookups, a lever placed near the toilet allows you to easily return to non-recycling mode.
By using filtered grey water in the toilet, you’re:
- Saving fresh water for better uses, like drinking
- Reducing inflow into your grey water holding tank
- Extending your dry camping days by avoiding a dump station trip
What the Kit Includes
The Extend Your Stay Tank Saver Kit is a collection of about 60 standard and hard-to-find parts that comprise Greg’s engineered and tested grey water recycling system. For $275 you’ll have access to the parts, a detailed step-by-step installation manual and any customer support you need from Greg himself. This price doesn’t include the secondary water pump, but to get more efficiency out of your entire fresh and grey water system, Corwin recommends reassigning your existing water pump to this system and purchasing a newer, better pump for your main house needs.
USI assures buyers that anyone who can operate a drill can install this system, but a little mechanical aptitude can definitely reduce the amount of time needed to complete the installation. Expect to set aside anywhere from two to four hours depending on your capabilities and knowledge about basic electrical connections, which you must perform in order to connect your new water pump to your system.
Worry-Free from Odors
Once installed you don’t need to worry about bacteria and odors coming from the recycled water. USI’s kit includes a premium carbon-wrapped filter that won’t restrict water flow but will help take away the particulates that can cause odors emitted from your grey water tanks. In addition, the implementation of good dry camping habits will also protect against that rotten egg smell. For example:
- Use a paper towel to clean all food debris from plates and cookware before washing in your sink.
- Purchase mesh drain covers to prevent large food particles from going down the drain.
- Only use your bathtub and sink for their intended purposes. All other waste should be put in the black tank through the toilet.
If you’re still skeptical about how this system will enhance your RV camping trips, you can purchase the company’s Gray Water Recycling Calculator, an inexpensive spreadsheet with embedded calculations that help you determine how much longer you can dry camp with this RV grey water recycling system once you input certain parameters like your dish washing frequency, daily toilet flushes, the number of people in the RV and more.
Better Camping, Cleaner Planet
RVers get quite creative when trying to boost fresh water tank capacity. With the Tank Saver system, you can skip the idea of adding a secondary water tank or bladder to your setup, and avoid touchy conversations about dumping grey water on the ground. Camping in the outback without hookups has never been easier and better for the environment.
