Outline Problem Definition System Requirements Engineering Design Norms Design Decisions Water Energy Project Obstacles Lessons Learned Acknowledgements
Problem Definition Community of Waspam, Nicaragua Lacks Access to Clean Water Working with World Renew to Design Solution
Current Solutions Available Clay Pot Filter Affordable Local Materials Low Flow High Maintenance Easily Breakable Earthy Taste Carbon Membrane Filter Affordable Low Flow Transportable High Maintenance Individual Scale
Our Solution Long Term Durable UV Disinfection System Powered by Solar Panels with a Grid Backup Water Purchased by Individuals in Community Preliminary Design
Engineering Design Norms Integrating Faith into Design Stewardship Cultural Appropriateness Humility Caring
System Requirements Compact Portable User-Friendly Long Design Life Meets Drinking Water Regulations Set by the World Health Organization Easily Maintained
System Design: Water Ultraviolet Light Prescreening 304 Micron 80 Micron Filter 5 Micron
Design Decisions: Energy Weight (1 - 5)Solar PVWind TurbineMechanical CrankGas GeneratorRiver Paddle Wheel Weather Resistant Initial Cost Operational Cost Durability Limited Amount of Components Easy Repair Energy Production Total
Design Decisions: Energy
Battery Size Limiting Factor Low Cost Design Quality Components Durability 10 hrs of Sun Provides 3 Days of Energy Needs
Project Obstacles Constructing Prototype Design Flow Meter Replacement Flow Switch to Manual Switch Fear of Making Mistakes Decision Making Constructing Design
Water Testing
Electronic Testing Fully Charged Battery Powers Unit for 10.5 Hours Flow Switch to Manual Switch On a Slightly Hazy Day in Grand Rapids: More Power Production Than Power Consumption Additional Testing of Battery Required to Verify Long Term Functionality [Solar Panel Racking System Photo]
Lessons Learned Design Tradeoffs Expect Delays Add Contingencies Time Finances Seek Help
