This project started as a pilot project where ToiletTech loaned a BTW urine diverting conveyor belt toilet seat to the State Park and did the installation at no charge. The seat was retrofit into an existing composting toilet building (Phoenix). The park operators were not satisfied with the frequency by which they needed to excavate the contents of the Phoenix compost toilet chamber and displeased by the quality and smell of the waste product. It was the objective of the ToiletTech pilot to prove that the urine could be diverted away from solid waste, urine sent directly to the pre-existing drainfield, and the solid waste decomposed onsite, using only native invertebrates found onsite. After its second year of use, the project was deemed a success in 2017 and the unit was purchased. The park indicated they desire to do more retrofits in the near future.
