“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.””

FlowFlow

800 gals per hour is the minimum flow rate that users would want accordingto our panel. 600 gals is too low. The current 4" metal pump is rated at1000 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.

The durability topic was big. Most field people think it will need to lastthree years to be of interest to farmers.  Or at least two years. We pushedthem a lot on this one. A one-year starter pump wouldn't be attractive theyclaim. 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 aproblem 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 onaverage. Typically for a couple hours in the morning and a couple hours inthe afternoon.
