1 According to a project approved by seven water NGO peers at Peerwater.org, including one from CARE. On the upper right of that page is the "Application Summary" that shows "Status: Approved Accepted". Notice the project description on this page.
Specifically, about halfway down, it says "One Repairs kit for the Chiefdom, maintenance kits for thirty villages and India Mark II pumps." This and other text makes it clear that the project is solely for maintenance for 30 pumps in 30 villages. Toward the bottom of the page, where it says "Budget Details" is a link to a budget file (click on the Microsoft Excel icon). At the page, click "Download" to view the project details in an Excel file.

In the Budget, on line 113, in the far right column, is the U.S. dollar-denominated cost of solely the equipment (spares) - not including the how-to-maintain and fix training - for thirty wells: $17,663.79.
