2 Eradicate the world's water crisis. Water4 uses inexpensive materials and easily-transferable technology Training, equipping and supporting nationals to be the solution to their own community's water needs.

4 System that can be used by handicapped people and small children without assistance from others Ensure it can be continually improved The go to system for all manually pumped water wells.

5 176 gallons/day vs. 5 gallon/day. 1 37% of people on the African continent currently live in a water-scarce environment people in Africa die every hour from poor sanitation, poor hygiene, and contaminated water. 3 ¼ of the population spends at least half an hour per trip to collect water. 3

8 Build a pump jack with a mechanical advantage Pumps water on the downstroke Make pump system more accessible

9 Materials must cost less than $150 Must be able to be built and repaired with materials and tools in the region Anchored to a 3 foot diameter concrete pad A flow rate of 4 GPM or higher.

10 Must be capable of being operated by handicap people and young children 2:1 mechanical advantage Ex: Instead of requiring 40 lb f, only 20 lb f will be needed

12 Most mechanically advantaged pump jack patents had expired by early 1900s, eliminating possible design conflicts

36 After 24 hours of testing, system did not show significant wear and operated well when attached to the electric motor. The pulley system kept the rack aligned.

37 Downstroke: F 1 = 40 lb f F 2 = 12 lb f F 1 F 2 = 3.3 Mechanical Advantage of 3.3:1 Upstroke: F 1 = 22 lb f F 2 = 13 lb f F 1 F 2 = 1.7 Mechanical Advantage of 1.7:1

38

39 Design goals were achieved The 2:1 mechanical advantage for the downstroke was exceeded by a 3.3:1 ratio The 2:1 advantage can be met on the upstroke with counterbalance but it will require more down force Construction of design was completed under budget by $5.82 We limited the stroke to 12 inches for optimum performance A flow rate of at least 5 GPM was maintained at 44 strokes/min Moves the pump handle off of the edge of the concrete pad

40 Paint the system Lubrication Bolt on horse s head Wrap inner portion of the pulley with a piece of tire inner tube Further wear testing
