Design Review 2 Water Drop 4
Ramu – the dollar-a-day farmer
• Lower caste farmer • 2-acre plot growing beans and sorghum but nothing
in dry season• Supports a family of 9; save half of crop for
consumption• Get my info from radio or rare city visits
• Dream: grow tomatoes or eggplants in the dry season
• Problem: The well has dried up, and flood irrigation is expensive and inefficient.
• Drip irrigation is great, but requires a gravity tank.
Design Review 2 Water Drop 5
So what’s wrong with the Gravity Tank?
• Too expensive at Rs 600 ($12)
• Unnecessary valve• Need elevated
place• Theft (Rs 600 is ½
month’s income!)
The Need: A better way to get water from storage to drip-irrigation

Maintenance
Holes may form . . .
But they can be easily patched!
Design Review 2 Water Drop 11
Ramu’s buying decision• Cuts 60% off gravity tank price
• Cost of the micro-irrigation system reduced from Rs 950 to Rs 550!
• Rs 400 savings = •10 day’s income •My child’s annual school fee •The cost of seed/fertilizer for another season •Drip-irrigation system for another 100 m2

A Scalable Manufacturing Process
• Simple, scalable components– rope, flat sheet, PVC, bar, tube
• Flat sheet made watertight– Pinched between bar and PVC
• Low capital investment– Local assembly possible at low
labor cost

Viable Economics• Manufacturing cost: $2.75
– Direct Materials: $2.50– 0.5 hours of labor: $.25
• Retail price: $4.50– ~30% markup for both manufacturer and
distributor
Building 16 units per day with one employee would make $13 profit per day!

Marketing and Distribution• Primary audience:
– $1/day farmers in semi-arid, monsoon, no groundwater availability.
• Reach via:– Drip irrigation system demonstrations (IDE)
• Movievans!– Demonstrations of Taapu by local manufacturers
• Distribution channels:– Local manufacturers– Local resellers

Refinement Pilot Tests Develop Local Partners Rollout
Timeline for Expansion
• First step: Refinement of Design– Eliminate leaks, reduce costs
• Next: Test with Ramu and Friends– Tips for further refinement
February Feb/March March -- ?
Design Review 2 Water Drop 17
Problems and Questions• Is it durable?• It’s not very attractive!• How best to repair it?• Does it take up too much
space?• Are there alternate uses?• Can Ramu assemble for
himself?

Potential Refinements

Expert TestimonyMartin FisherTechnical Director, ApproTEC
•Cost Reduction is Key•Must determine appropriate bag size for market
- How often replenished?•User perspectives of “quality” may vary
Design Review 2 Water Drop 20
Summary and Conclusions• Current IDE Gravity Tank needs improvement
• A much cheaper, higher volume tank can be profitably manufactured
• All components are scalable, and bags could be manufactured or assembled locally
• A number of design problems remain to be solved
