EWB-USA Overview
A non-profit humanitarian organization established to partner with developing communities worldwide in order to improve their quality of life
Involves the implementation of sustainable engineering projects, while involving and training internationally responsible engineers and engineering students
EWB-USA History
Founded by Dr. Bernard Amadei, at the University of Colorado at Boulder, in April 2000
First Project – San Pablo, Belize water supply system Mobilized 8 University of Colorado students, forming
the founding members of the first chapter Demonstrated the potential of professional and student
engineers working together
EWB-USA Mission Statement
To partner with developing communities to improve their quality of life through the implementation of environmentally sustainable, equitable, and economical engineering projects.
In the process of working to advance developing communities, EWB-USA promotes the development of globally aware and internationally responsible engineers, students, and professionals

Water Tank & Tower Installation Goals:
Elevate the 2500-liter tank currently on ground Locate tower for this tank Construct the concrete tower footings Isolate the current tower for continued facility water service. Install the tank
Elevate the new 5000-liter tank Construct the concrete footings for the second new tower. Install the tank
Connect tanks
