About Critical Practices...
And what we're up to
Critical Practices LLC is a USA based organization that provides services for design and implementation of sustainable technologies. The EarthAuger Composting Urine Diverting Dry Toilet (EA) has been the result of 13 years of development by Critical Practices LLC (CP). The original concept and subsequent prototype of the first EarthAuger was developed by University of Washington professor Chuck Henry in 2001.
The goal was to have a toilet that could:
- be installed inside the house and get treated solids and liquids out of the house, while avoiding smells and flies
- create usable end products
- operate effectively without power or water
- Through 2010 development of the EA was by Henry, supplemented by some University of Washington funds for materials and demonstration projects.
- In 2011 The Bill and Melinda Gates Foundation provided a Grand Challenges Phase I grant to enhance the interface of the toilet to make it more user friendly – the grant was through the Ecuadorian non-profit Fundación in Terris (FIT) with CP as a subgrantee. The success of these enhancements during that grant period resulted in a Phase II grant to commercialize the EA, again through FIT providing field testing and CP doing development and manufacturing.
- By 2014, all components were redesigned, molds were fabricated, and 650 units of the injection molded plastic model were produced. Of these:
- 435 toilets were sent Ecuador
- 25 to Seattle for testing and small demonstrations
- 190 remained at the factory for use in large-scale demonstrations
In addition to being supported by the Bill and Melinda Gates Foundation, CP recently received funding from the Washington Global Health Alliance (WGHA) for development of a community sanitation system.
Currently, CP’s work consists of continued:
- UDDT & Community system demonstrations
