This toilet was the first of its kind in North America and achieves urine diversion with a mechanism powered by the opening and closing of the door. This was an invention by Geoff Hill prior to his licence of the Ecodomeo Behind the Wall urine diverting conveyor in North and South America. The system is still operating but ToiletTech's preference is for the BTW conveyor seat. The structure of this toilet is of PanAbode cedar double T&G wall boards. It is fully bear proof. The system is highly functional and produces a highly stabilized end product each year that the operator utilizes in his onsite Waste Water Treatment Plant for annual startup for its microbial diversity.
