“Dr. Jerry Dean Epps says the Eppivent is a waterless toilet that requires no electricity and has no bad smells. No working with waste required like with compost toilets. Internal flush moves contents out of sight. Waste is digested in main tank, moves through the bio-filter tank and the small amount of liquid discharged is safe for the environment but we send it to an underground evaporation/transpiration bed anyway. It is a stand alone and completely deals with waste on site.”
