This paper combines 172 Demography and Health Survey data sets from 70 countries to estimate the effect of water and sanitation on child mortality and morbidity. The results show a robust association between access to water and sanitation technologies and both child morbidity and child...

A management model provides the framework in which the roles and responsibilities of all the participatory forces that have a stake in the water supply and sanitation services sector are defined. In an effort to make service providers more accountable to citizens and due to the need to empower...

To many, reducing water losses is seen as key to more sustainable water management. The arguments to reduce water losses are compelling, but reducing water losses has turned out to be challenging. This paper applies a panel data analysis with fixed effects to determine the major drivers of...

The lack of an appropriate regulatory environment is a principal factor behind inadequate water and sanitation services in many parts of Latin America. Many governments recognize the need to improve cost recovery and accountability in services - and increasingly see private sector participation...

The authors show how willingness to pay surveys can be used to gauge household demand for improved network water and sanitation services. They do this by presenting a case-study from Sri Lanka, where they surveyed approximately 1,800 households in 2003. Using multivariate regression, they show...

Standpipes that dispense water from utilities are the most common alternatives to piped water connections for poor customers in the cities of Sub-Saharan Africa. Fifty-five percent of the unconnected urban population relies on standpipes as their first water source. Other informal water...

Water and sanitation utilities in Africa operate in a high-cost environment. They also have a mandate to at least partially recover their costs of operations and maintenance (O&M). As a result, water tariffs are higher than in other regions of the world. The increasing block tariff (IBT) is the...

From 1994 onward, Bolivia undertook a major reform of its infrastructure sectors. The authors examine the impact of the reforms from the perspective of poor households in the adjacent cities of La Paz and El Alto, particularly in terms of access to services. Different policies adopted across the...

Using data from the International Benchmarking NETwork database, the authors estimate measures of density and scale economies in the water industry in four countries (Brazil, Colombia, Moldova, and Vietnam) that differ substantially in economic development, piped water and sewerage coverage, and...

The Bolivian government awarded a concession for water and sewer services in La Pazand El Alto in 1997. One goal of doing so was to expand in-house water and sewer service to low-income households. The author uses the Aguas del Illimani case to explore how the design of typical concession...
