3 Types of Toilets
We offer three types of toilets. Each toilet is waterless and doesn't require power or bulking agent of any kind. We provide complete toilet kits which include a seat (riser), toilet building, and waste vault. For front-country road accessible sites, we offer a standard pump-out vault toilet that costs less and looks better than the CXT. For back-country sites, we offer two options: the Decompose for sites with soil and vegetation and the Waste-Away for extreme environments like the alpine.
Mixed Waste / Vault Toilet
The mixed waste vault toilet consists of a Wishbone structure and a conventional riser seat above a vault; it does not divert urine and requires pump-out service.
Decompose or Waste Away?
The Decompose toilet utilizes the Behind-The-Wall urine diversion seat and functions as a composting toilet should, promoting decomposition of the solid waste, without the need of bulking agents or mixing. Units are sized to provide 10-20 years of waste retention in a 2-4' deep pre-fabricated open bottom vault (TTS DCV). This is possible because the urine diverted solid waste is consumed by invertebrates (they actually eat it, obtaining energy and nutrients from it). No bulking agent is necessary because urine (wet and smelly) is diverted into a shallow septic field for onsite treatment. This system evolved out of Toilet Tech's founder's PhD research.
Benefits: Produces lowest residual waste volume with onsite storage capacity of 10-20 years
Drawbacks: Requires excavation into soil, 2-4' below grade
Site Suitability: Forests, campgrounds, sub-alpine, remote parking lots, some front country sites

The Waste Away Toilet utilizes the BTW Urine Diversion Seat but collects dry, solid waste directly into structural bags or bins for hassle-free removal. The Waste Away toilet has replaced dozens of high-use high-alpine helicopter fly-out toilets including all the high camp toilets on Mt. Rainier National Park, Longs Peak in Rocky Mountain National Park, and Zion's Angel's Landing trail. Operators report 1/5 the hauling cost and 1/5 the waste volume as compared to the previous collection of mixed waste in fly-out drums. Waste can be collected in bags small enough for llamas to carry (as is done on Longs Peak) or in large 1 cubic yard stiff sided haul sacks. A single large tote bag can capture the waste of up to 10,000 toilet users per year. Download our planning and sizing guide to learn more.
No-touch waste collection system. Easiest storage, removal and disposal.
Waste is not decomposed and requires disposal (landfill, incineration, WWTP)
High elevation alpine or extreme desert locations (like Zion's Angels Landing)
