Interested in getting a composting toilet for your home or are you building a new home and plan to install a composting toilet? This document will help step you through permitting requirements.
Arizona Department of Environmental Quality (ADEQ) approved, on December 28, 2016, for permitting the construction and use of two site-built designs piloted by Watershed Management Group through a two-year process with 22 participating sites. The Proprietary Treatment Product Listing for the two designs now expands the range of composting toilet options available to Arizonans. The two batch-style composting toilet system designs are 1) a 55-gallon barrel system and 2) a masonry chamber system.
