RV Waste Water Treatment
Below is a quote!
"One concern I had about recommending no chemicals in the holding tank was that we were hooked up to a sewer system at the time so I could completely rinse my blackwater tank each time I flushed it (about every ten days). I thought I might think differently once I began the boondock lifestyle. Well, it's been nearly a year since we began boondocking and we still use no chemicals in our holding tanks. I DO wash out the graywater holding tank with vinegar every chance I get because it does create a foul odor if I don't but still nothing in the blackwater tank."
