We estimate the impacts of two interventions implemented as field experiments in informal settlements by Nairobi’s water and sanitation utility to improve revenue collection efficiency and last mile connection loan repayment: (i) face-to-face engagement between utility staff and customers to...

Nearly 40% of England's privately built waterworks were municipalised in the late 19th century. We examine how this affected public health by pairing annual mortality data for over 600 registration districts, spanning 1869 to 1910, with detailed waterworks information. Identification is aided by...

Beginning around 1880, public health issues and engineering advances spurred the installation of city water and sewer systems. As part of this growth, many cities chose to use lead service pipes to connect residences to city water systems. This choice had negative consequences for child...

Urban water conservation is typically achieved through prescriptive regulations, including the rationing of water for particular uses and requirements for the installation of particular technologies. A significant shift has occurred in pollution control regulations toward market-based policies...

Fresh water supplies increasingly are under stress in many parts of the world due to rising populations, higher per capita incomes and corresponding consumption, greater environmental concerns, and the effects of climate change. Water rights and markets are part of the institutional menus for...

Poor water quality and sanitation are leading causes of mortality and disease in developing countries. However, interventions providing toilets in rural areas have not substantially improved health, likely because of incomplete coverage and low usage. This paper estimates the impact of an...

Providing clean water requires maintenance, as well as the initial connections that are typically measured. Frequently, the water supply fails in the developing world, especially when users don't pay the marginal cost of water. This paper uses the timing of frequent, unexpected water service...

The construction of municipal water systems was a major event in the history of American cities -- bringing relief from disease, providing resources to combat fires, attracting business investment, and promoting development generally. Although the first large-scale municipal water system in the...

Historically, improvements in municipal water quality reduced mortality substantially in wealthy countries. However, water disinfection has not produced equivalent benefits in developing countries today. We investigate this puzzle by analyzing a large-scale municipal water disinfection program...
