This evaluation planned to employ a continuous treatment approach to understand how different levels of water supply affect behavior at the household level. This design relied on a critical assumption that increasing water production at water treatment plants would automatically result in more water per customer. This assumption was not realistic and did not hold, which posed a challenge for being able to attribute the results of the continuous treatment analysis to MCC’s investment. Future applications of this methodology must carefully consider attribution and validation of outputs and intermediate outcomes.
