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.

Well-run water utilities play an important role in ending poverty and boosting shared prosperity. Consumers need reliable access to high quality and affordable water and sanitation services. To deliver these basic services efficiently and effectively requires high-performing utilities that are able to respond to urban growth, to connect with the poor, and to improve wastewater disposal practices. The International Benchmarking Network for Water and Sanitation Utilities of the World Bank's Water and Sanitation Program (IBNET) has been involved in water sector monitoring since 1997.

Investments on the order of $US6 billion are estimated to be needed in the water sector in Nigeria in the next 10 years if the country is to achieve universal water supply coverage. This is the main finding of State Water Agencies in Nigeria: A Performance Assessment. The report focuses on water provision services from the state water authorities (SWAs), or water boards, as they are the major and only regulated agencies that provide water to the urban population. Sanitation provision is not addressed because the majority of SWAs do not provide this service to their customers. This report highlights the issues related to the performance of SWAs, tariff levels and structures, financing mechanisms, and concerns with governance within the SWAs and state governments. For example, as a result of accelerated urbanization and migration of the population to the large cities, the average coverage by SWAs is about 40 percent, and the average domestic water consumption was 26 liters per capita per day in 2013, well below the recommended average. The remaining majority of the population relies on alternative service providers. To the extent possible, the report also shows how institutional weaknesses affect customer costs, subsidies to the sector, and the financing required to scale up investment. It showcases how the related operational and maintenance expenditures of the SWAs can actually be covered from the various financing sources. Coping costs of the population getting water from alternative water providers is assessed at US$700 million a year, and this number is growing. In addition, utilities get about US$100 million in operational subsidies that cover labor, electricity, and other operational costs. State Water Agencies in Nigeria: A Performance Assessment provides the government of Nigeria with a structured and coherent quantitative snapshot of the state of its urban water sector. Ultimately, this report is a first step toward performance benchmarking in Nigeria's water and sanitation sector. The findings summarized in this publication should eventually serve as a tool for utilities and their authorities and stakeholders, as well as for bilateral and multilateral donors, in their efforts to monitor the performance and progress of each water provider and the sector as a whole.

This report explores how scarce public resources can be used most effectively to achieve universal delivery of water supply and sanitation services. It analyzes the prevalence and performance of subsidies in the sector, then guide policymakers on improving subsidy design and implementation to improve their efficacy and efficiency in attaining their objectives.

Establishing and maintaining public water services in fragile states is a significant development challenge. In anticipation of water infrastructure investments, this study compares drinking water sources and quality between Port Harcourt, Nigeria, and Monrovia, Liberia, two cities recovering from political and economic instability. In both cities, access to piped water is low, and residents rely on a range of other private and public water sources. In Port Harcourt, geographic points for sampling were randomly selected and stratified by population density, whereas in Monrovia, locations for sampling were selected from a current inventory of public water sources. In Port Harcourt, the sampling frame demonstrated extensive reliance on private boreholes and a preference, in both planned and unplanned settlements, for drinking bottled and sachet water. In Monrovia, sample collection focused on public sources (predominantly shallow dug wells). In Port Harcourt, fecal indicator bacteria (FIB) were detected in 25% of sources (N = 566), though concentrations were low. In Monrovia, 57% of sources contained FIB and 22% of sources had nitrate levels that exceeded standards (N = 204). In Monrovia, the convenience of piped water may promote acceptance of the associated water tariffs. However, in Port Harcourt, the high prevalence of self-supply and bottled and sachet drinking water suggests that the consumer's willingness to pay for ongoing municipal water supply improvements may be determined by service reliability and perceptions of water quality.
