The government constructed hand pump is labeled by the team with a red circle, so the water fetchers can easily indicate what source they utilized in their water diaries.

Challenge:
Can we invent low-cost, remote sensors to better understand water fetching practices in the developing world?
Research Strategy
- Design and develop low-cost sensors that are adaptive to a variety of household water collection devices
- Provide households these sensor-enabled water collection devices (“smart buckets”) that collect data on households water fetching practices: distance to water source, fetching time, volume fetched, and water source selected
- Validate sensors under field conditions by comparing data obtained from “smart buckets” with household water diary surveys, where households self-report information on their water fetching
Project description
Since the discovery of arsenic in wells in Eastern India in the late 1980s, governments and nongovernmental organizations have sought to address the problem in rural villages by providing safe community water sources. Yet despite access to safe alternatives, many households still fetch and consume water from contaminated wells. As a result, approximately 40 million people across the region are at elevated risk of cancer, stroke, and heart disease from arsenic present in drinking water and cooked food. Women are the primary water fetchers for most families in rural India, but the scarcity of data on exactly how women choose water sources makes it difficult to develop strategies to reduce arsenic exposure.
Automated data collection of water fetching practices in the developing world could offer a cheap and accurate way to gather data with greater geographic scope and breadth. In this project, Bessette and Sampath are working on small sensors to be placed inside water fetching vessels to create “smart buckets” that can help obtain a clearer picture of fetching practices in arsenic affected villages. By demonstrating the efficacy of a sensor-based approach to understanding water fetching practices, the researchers hope to address a major data gap in international development.
Outcomes
- Designed a low-cost, mass-manufacturable sensor that can be used to understand water fetching in remote areas around the world
- Validated the sensor functionality with over 200 families in rural India by conducting surveys, interviews, and water diary studies
- Discovered that fetching behavior is often influenced by social factors, which create unintuitive behavior, like walking longer distances to fetch water or switching to lower quality water sources
