Our goal is to have a working prototype for more efficient dewatering of human fecal sludge with a mode for agitation. Additionally, the prototype will have an efficient way to disassemble and/or clean the device while still maintaining dignity for the user.
Criteria for Acceptance:
- Achieve solid by mass content of waste after filtration (>15%)
- Filter should be replaceable and/or easily disposable
- System should be easily cleanable and/or filter replaceable
- Full preservation of human dignity for the user
- Device should have a cost/sq. ft reduction and still be able to process (volume of waste/time, 10^3 m per day)

“This was the most fulfilling engineering course I have taken at UT,”
– Annie Bourland
“This course is a very good experience especially if you want to go into design/product development in the future. It also looks very good on resumes and is a great talking point for recruiters! I would highly recommend.”
