Impact of Low-Cost In-Line Chlorination Systems in Urban Dhaka on Water Quality and Child Health
- Location: Bangladesh
- World Bank contact: Pratibha Mistry
- Principal investigator: Stephen Luby, Stanford University
- Timeline: January 2013 to January 2016
- Evaluation: In Bangladesh, limited water supply and poor sanitation infrastructure in dense slums is associated with high rates of child diarrhea, stunting, and wasting. Yet central treatment and delivery of water supply is prohibitively expensive for municipal governments to implement in low-income areas. Point-of-use water treatment has been developed as an alternative, but uptake among at-risk households remains low. To address this problem, the government has started to administer automated chlorination at water dispensing sites in poor areas. Researchers seek to determine the effectiveness and cost-effectiveness of using automated chlorination in reducing child diarrhea and other water-borne illnesses.
Improving Access to Safe Water in Semi-Arid Areas Through Rainwater Storage Cisterns
- Location: Brazil
- World Bank contact: Juliana Garrido
- Principal investigator: Paul Gertler, University of California, Berkeley
- Timeline: September 2010 to June 2014
- Evaluation: In Brazil, access to clean water in rural, semi-arid areas is a recurring problem. Researchers will evaluate the impact and cost-effectiveness of a project designed to improve access to safe water in semi-arid areas through the use of rainwater storage cisterns. The evaluation will help determine how best to scale up the use of cisterns to provide clean water to affected areas and improve child health outcomes.
Incentivizing Sanitation Uptake and Sustainable Usage through Micro Health Insurance
- Location: India
- World Bank contact: Manish Kuman
- Principal investigator: Orazio Attanasio, University College London
- Timeline: June 2012 to March 2016
- Evaluation: India accounts for 33 percent of the global population without access to safe water and adequate sanitation. At the same time, the number of Indians with health insurance coverage is low, and out-of-pocket expenditures pay for most health care costs. Researchers will examine the link between improved health status and reduced health expenditures in poor areas of rural India by evaluating the effects of a community-based health care program and a sanitation program that provides access to credit to construct safe sanitation systems.
Turning Pipe Dreams into Reality: Maximizing the Impact of Sanitation and Water Pipe Infrastructure through Connection Subsidies and Life Skills Training
- Location: Kenya
- World Bank contact: Arianna Legovini
- Principal investigator: Arianna Legovini, World Bank
- Timeline: May 2012 to December 2015
- Evaluation: In Kenya, researchers will study the effects of combining a social intervention (water storage and hand-washing) with a traditional supply-based intervention (providing access to better water and sanitation) to determine the best way to increase hygiene. The results will help development experts in Kenya and elsewhere determine how best to encourage behavioral changes that can improve water quality, hygiene, and health status.
