The IBNET Water Supply and Sanitation Performance Blue Book
(World Bank, 2011)The International Benchmarking Network for Water and Sanitation Utilities (IBNET) blue book creates a baseline and, at the same time, offers a global vision of the state of the sector in developing countries. By tracking progress in and quantifying and assessing the water supply and sanitation sectors, IBNET helps meet the goal of providing safe, sustainable, and affordable water and sanitation for all. This report serves three purposes. First, it aims to raise awareness of how IBNET can help utilities identify ways to improve urban water and wastewater services. Second, it provides an introduction to benchmarking and to IBNET's objectives, scope, focus, and some recent achievements. Third, it elaborates the methodology and data behind IBNET and presents an overview of IBNET results and country data. By providing comparative information on utilities' costs and performance, IBNET and this study can be used by a wide range of stakeholders, including: 1) utilities: to identify areas of improvement and set realistic targets; 2) governments: to monitor and adjust sector policies and programs; 3) regulators: to ensure that adequate incentives are provided for improved utility performance and that consumers obtain value services; 4) consumers and civil society: to express valid concerns; 5) international agencies and advisers: to perform an evaluation of utilities for lending purposes; and 6) private investors: to identify opportunities and viable markets for investments. -

Performance of Water Utilities in Africa
(World Bank, Washington, DC, 2017-03)Africa’s urban population is growing rapidly. Between 2000 and 2015, the urban population increased by more than 80 percent from 206 million to 373 million people. Although access to piped water increased over the period (from 82 million urban dwellers with piped water in 2000 to 124 million in 2015), African utilities were not able to keep up with the rapid urbanization as reflected in the decline of piped water as a primary source of water supply in percentage terms. The objective of this assessment is to inform Bank and government policies and projects on the drivers of utility performance. The report describes the main outcomes and lessons learned from the assessment that identified and analyzed the main features of water utility performance in Africa. The report includes the following chapters: chapter one gives introduction, chapter two describes the methodology used in the study, including details on the data collection process. In chapter three, the study team undertook a trend analysis of utility performance of the sector. Chapter four examines the efficiency of utilities using a data envelopment analysis (DEA) while also using an absolute performance approach. Chapter five investigates the effect of institutional factors on utility performance. Chapter six presents an econometric analysis of the drivers of utility performance, using various definitions of utility performance. The results from the econometric models are triangulated with a set of case studies of five utilities (Burkina Faso’s l’Office National de l’Eau et de l’Assainissement (ONEA), Cote d’Ivoire’s la société de distribution d’eau de la Côte d’Ivoire (SODECI), Kenya’s Nairobi City Water and Sewerage Company (NCWSC), Senegal’s Sénégalaise des Eaux (SDE), and Uganda’s National Water and Sewerage Corporation (NWSC), similar to those that the electricity study team undertook, which are presented in chapter seven. The report concludes in chapter eight with the lessons learned from the assessment. -

Guidance Note : Public Expenditure Review from the Perspective of the Water and Sanitation Sector
(World Bank, Washington, DC, 2012-06)The objective of this guidance note: public expenditure review from the perspective of the water supply and sanitation sector is to provide World Bank staff with a body of knowledge and good practice guidelines to help them evaluate the allocation of public resources to water and sanitation services in a consistent manner and to increase their knowledge of public expenditure issues in the sector. This guidance note discusses the challenges that are specific to public expenditure management in water and sanitation and the difficulties often involved in identifying sector expenditures. The challenges particular to this sector stem from three factors. First, countries define water and sanitation differently (e.g., drainage may or may not be included, rural services may be considered separately). Second, responsibilities for water and sanitation policy are often divided horizontally across government ministries and agencies, vertically between national and local governments and functionally among the public, private, and non-governmental sectors. Third, the roles of these multiple actors may be unclear or overlapping. -

Investing in Water Infrastructure : Capital, Operations and Maintenance
(World Bank, Washington, DC, 2012-11)This paper provides background information for development practitioners in the water and other infrastructure sectors. It outlines the major challenges related to financing the gap in global water infrastructure, including those systems that provide urban and rural water supply, and sanitation and irrigation services. Water infrastructure finance includes costs for capital works as well as the operations and maintenance costs that motivate sustainable service delivery. Section one introduces the linkages between water infrastructure and growing global challenges, including food and energy security as well as climate change. Section two describes investment needs in the sector and details various traditional funding sources. Section three proposes a five step reform cycle for making better use of limited funding in the sector. Tools for making these improvements are outlined in section four. The paper concludes with section five, a summary of the challenges and recommendations for the way forward. -

The Drivers of Non-Revenue Water : How Effective are Non-Revenue Water Reduction Programs?
(World Bank Group, Washington, DC, 2014-08)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 non-revenue water, which is define as the volume of water losses per kilometer of network per day. The analysis uses data from the International Benchmarking Network for Water and Sanitation Utilities, covering utilities in 68 countries between 2006 and 2011. The analysis finds that non-revenue water is driven by many factors. Some of the most important drivers are beyond the control of the utility, such as population density per kilometer of network, the type of distribution network, and the length of the network, which are largely the result of urbanization and settlement patterns in the localities that the utility serves. The opportunity costs of water losses are also key in explaining what drives non-revenue water. The paper finds that very low opportunity costs of water losses have an adverse effect on the reduction of non-revenue water. Country fixed effects turn out to be important, meaning that the environment in which the utility operates has an important impact on non-revenue water levels. An important conclusion is that the design of non-revenue water reduction programs should study the main drivers of non-revenue water to provide utility managers with a better understanding of what can be achieved in terms of non-revenue water reduction and whether the benefits of these reductions exceed their costs. -

Heterogeneity in the Cost Structure of Water and Sanitation Services : A Cross-Country Comparison of Conditions for Scale Economies
( 2010)The main purpose of this article is to compare the cost structure of water utilities across a set of 14 countries with different levels of economic development. As far as is known, the cross-country perspective is novel in this literature. This article first provides new measures of returns to scale in the water and sanitation sector for a set of countries, most of them from the developing world. It is then shown that the probability of a utility operating under decreasing, constant, or increasing returns to scale depends not only on its characteristics (the volume of water produced in particular), but also on the country's level of economic development (gross national income) and business environment as measured by investor protection, the cost of enforcing contracts and perceptions of corruption.
