Project BackgroundB9 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 StatementThe 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 secondsGap between UV light and waterType 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.

3

Project ObjectivesRun “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.

Expected Project BenefitsAllow users in

developing countries access to disease-free water.

Improve RIT’s reputation in environmental sustainability.

Assumptions & ConstraintsUV disinfection system treats ½ gallon of water per

minuteManual power generation must generate at least 17

watts of powerTotal system cost must be less than or equal to

$100/unit for 1000 unitsUV lamp needs 10 second lead timeMust use off the shelf partsCannot alter UV disinfection system
