3. Our Point of View S mall-plot farmers need a cheaper pump so they can get a better pump S mall-plot farmers need a cheaper pump so they can get a better pump PumperNickel: PumperNickel: It will take some bread, It will take some bread, but not much… but not much…

4. Our Customers Name

5. Nanda-thida  Open well or pond  Tube well – hand pump  Maung dat – own land  Maung dat – rented land

6. It’s What the Farmers Need “ … when we mentioned there was a team looking at a $5 pump - boy did they light up! They all said a lower cost pump would be fantastic.” “There is so much interest in the metal pump, but people just don't have the money to buy it. So lowering the price point considerably would be huge.” ” “During our meeting yesterday, we had a long discussion with our field staff talking about why more potential users are not buying the pump. The NUMBER ONE reason is people don't have enough money to even afford our $13 pump.”

7. Design Requirements Req Justification Flow 800 gals per hour is the minimum flow rate that users would want according to our panel. 600 gals is too low. The current 4" metal pump is rated at 1000 gals/hr. They also said as long as the water output is greater than a hand pump (which is 400 gals/hr) then people would see it as a viable option. Durability Price The durability topic was big. Most field people think it will need to last three years to be of interest to farmers. Or at least two years. We pushed them a lot on this one. A one-year starter pump wouldn't be attractive they claim. A two or three year pump would have to come with a guaranty from IDE. Interestingly, this group said a one to two year pump life would not be a problem at all - if the cost was low. When asked about the potential market size, everyone said it would be bigger than the current market for the metal pump. At $5 it would be huge, at $10 less so. It is a steeply sloped demand curve! Our surveys show that people use the treadle pump for 4.5 hours a day on average. Typically for a couple hours in the morning and a couple hours in the afternoon.

8. Water Displacement

9. Rope and Washer

10. Diaphragm

11. Plastic Pump

12. Basic Economics: “The Rump”  Will the pump get the farmers to the next stage?  Cost of tube well = $20  Cost of metal pump = $15  Acre of Land = $400 NPV for “one-year” pump Cost of Pump = $8 Profit from Crop = $100 One Crop Two Crops Cost of Capital = 10% Cost of Capital = 20% $60.30 $63.48$40.23 $106.95

13. Our Future Explorations  Is a bamboo piston viable? What about a bamboo diaphragm?  Can we build a one piston pump?  Honing in on blow molding and injection molding  “Degrading” test of rope and washer

14. Vulnerability – potential pitfalls  Rope and Washer not high enough quality to last even one season – how long will it take for the rope/cloth to degrade?  There isn’t enough bamboo, and it isn’t strong enough to be the pump body  Blow-molding or injection molding is just too expensive  We can’t lift the water enough to make any of our solutions viable for most farmers  We’re missing major “social input” – what do the farmers want this to look/feel/act like? Is cheap sufficient?  Frame for plastic pump
