Mentor: Dr. DeBartolo
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
o
o
o
Water Sanitation
Energy Generation
Portable Dry Toilet
Rain-water Collection
Urine Diversion (UD) Toilet from SOIL
Background
•
Living conditions in Haiti
o
o
o
o
o
o
o
o
o
Poverty stricken (GDP per capita of $1200)
Ineffective central government.
Little law enforcement.
Untreated water sources contaminated with animal
and human waste.
No active sewage system.
Most people are subsistence farmers.
Many people have cell phones.
No electricity in homes.
Very little education available.
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.

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
o
o
o
o
Extreme deforestation
Soil Erosion
Droughts
Flooding
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
