4. Problem Definition Problem Community of Waspam, Nicaragua lacks access to clean water Our solution Long term durable UV disinfection system powered by solar panels with a grid backup Water purchased by individuals

5. System Requirements Compact Portable User-friendly Long design life Meets drinking water regulations set by WHO Easily maintained

6. System Design: Water Ultraviolet light Prescreening 304 micron 80 micron Filter 5 micron

7. Design Decisions: Energy Weight (1 - 5) Solar PVWind Turbine Mechanical Crank Gas GeneratorRiver Paddle Wheel Weather Resistant 541442 Initial Cost 431452 Operational Cost 555315 Durability 552232 Limited Amount of Components 342242 Easy Repair 222433 Energy Production 551254 Total 145123598510385

8. Design Decisions: Energy

10. Battery size limiting factor Low cost design Quality components Durability 1.5 hrs of sun = 3 days of energy needs

12. Current Status Constructing prototype design Creating solar panel racking system Testing design Creating owner’s manual

13. Future Work Adding LEDs to indicate when it’s safe to start filling containers Packaging system and shipping out

14. Lessons Learned Design tradeoffs Expect delays Long testing time Seek help
