Designed, tested, and refined over the years by David Omick, a local southern Arizona expert, the barrel composting tiolet system is practical and cost effective. This toilet design features a series of 55-gallon high-density polyethylene barrels as the collection and composting container. A customized HDPE panel top serves as a removable lid and a seat, vent, and light trap platform. To compliment the barrel composting toilet design a low-cost, practical urine diversion system is included to provide additional nutrients to your plants.

If you are potentially interested in purchasing a kit (includes Compost Crank for easy maintenance) to take home please note the following costs:
- 2 barrel system - $ 755.00

Please note that these systems are listed on Arizona Department of Environmental Quality's (ADEQ) approved composting toilet list, which means you may be able to permit your system for use. If you decide to permit your system then a typical permit may cost $500 if you reside in Pima County Department of Environmental Quality (PDEQ permit) or up to $1000 if your county delegates authority back to Arizona Department of Environmental Quality (ADEQ).
