Project Description• Identify methods to harvest waste
power generated by people for end use in Haiti.
• Low cost designs to improve quality of life such as:o Water Sanitation o Energy Generationo Portable Dry Toileto Rain-water Collection
Urine Diversion (UD) Toilet from SOIL

Background • Living conditions in Haiti
o Poverty stricken (GDP per capita of $1200)o Ineffective central government.o Little law enforcement.o Untreated water sources contaminated with
animal and human waste.o No active sewage system.o Most people are subsistence farmers. o Many people have cell phones. o No electricity in homes.o Very little education available. o Very religious.

Background cont.UV sanitation pumps are currently being
developed by B9 Plastics and RIT to eliminate bacteria in dirty water and make it safe to drink.

P11412 • Improve UV Water Sanitation System:
Senior Design Project o This project revolved around the
improvement of a current UC Berkeley project to eliminate contamination in the event of component failure.

Sanitation in Haiti• From 1998-2008 the percent of Haitians that
had access to "improved sanitation" went down from 45%-24%
• Only 14% of rural Haiti has access to "improved sanitation"o 'Improved Sanitation' means any sort of
waste sanitation beyond squatting in a bucket
• Today over 70% of Haiti is without proper sanitation

Agriculture in Haiti• 1950's: Employed 80% of Workforce, 50% of Nation's GDP, 90%
of Exports
• 1980's: Employed 66% of Workforce, 35% of Nation's GDP, 25% of Exports
• Today's decline in Haitian Agriculture is due to:o Extreme deforestationo Soil Erosiono Droughtso Floodingo Natural Disasters

Composting & Toilets in Haiti• Haitians have a need of a proper toilet (lavatory, lav, can, john,
privy, bathroom, commode, crapper, pot, potty, stool, throne, head, loo, plopper) for defecation and urination
• Due to the lack proper sanitation systems Haitians inevitably find the need to dispose of their... waste products
• To do so a common practice is to implement a:
Humanure Composter!!!• Using the waste from the toilet as fertile
soil for agricultural needs

Stakeholders• Sarah Brownell - Worked in Haiti for
10 years. • B9 Plastics - Sponsor for the UV
water disinfection design (Better Water Maker).
• Alex Martinez - Student in with a toilet and composter concept.

Next Steps• Determine what project path holds the
highest potential for major impact in the Haitian community and/or developing nations worldwide.
• Generate engineering specs from customer needs
