Project Background B9 Plastic’s Better Water Maker strives to provide clean, disinfected water to over 800 million people worldwide. The current system treats ½ gallon of water per minute by the use of a manual hand crank to provide power to the pump and UV light. The water passes by the UV light where it is sanitized. Previous Projects One design utilized a hand crank flywheel as a method of power generation. Second design improved upon the first and used a recumbent foot petal instead of the hand crank. Third design focused on removing the turbidity of the water by the use of a French press style of filter. Previous iterations of the projected were regarded as good ideas but were not executed.

Problem Statement The goal of this project is to create a cheaper system that requires less effort to operate and is fun for women and children to use. Cost of the system must be reduced to $100/unit for 1000 units. The components of the UV system must not altered. Lamp must be powered on for 10 seconds Gap between UV light and water Type of bulb The complete system should be mobile and lightweight to allow for easy storage. Fully functioning prototype must be completed by the end of MSD II.

Project Objectives Run “some amount” of <5 turbidity water through the UV system to sanitize it to “certain level”. Redesigned mechanical power generation system. Reduced cost from $200/unit to $100/unit. System is easy and fun to use.

Deliverables Completed BWM that meets the needs of the users and B9 Plastics Bill of materials Design drawings for manufacturing or modifying by users Assembly plan User manual for low literacy users Test plan and documented results

Expected Project Benefits Allow users in developing countries access to disease-free water. Improve RIT’s reputation in environmental sustainability.

Assumptions & Constraints UV disinfection system treats ½ gallon of water per minute Manual power generation must generate at least 17 watts of power Total system cost must be less than or equal to $100/unit for 1000 units UV lamp needs 10 second lead time Must use off the shelf parts Cannot alter UV disinfection system

Issues & Risks Project Risks Technical Risks Keeping unit cost under $100 Not finishing before ImagineRIT or at all New topics that team is not familiar with Technical Risks Product is not safe to use Failure modes not accounted for before production Users have no interest in product (not fun to use) Lifetime of product not to desired length
