This paper assesses the cost and benefits of "diggies”, the intermediate water storage structures in the
Indira Gandhi Nehar Pariyojana project in Rajasthan. A diggi helps provide reliable water deliveries to farms and
that in turn expects to increase crop production. Our analysis shows that through better water control, farmers with
diggi's have increased cropping intensity, input application and crop productivity. The net value of crop production
per ha of irrigated area of farms with diggi's is 68% higher than that of farms without diggi. A cost-benefit analysis
shows that diggi is a financially viable intervention for farms with size larger than 4 ha
