The objective was to address water and sanitation tariffs in Africa, along with their relationship to cost recovery, cross-subsidies, and financial sustainability. The study was conducted on 45 water utilities from 23 countries in Africa in 2006-2007.
Middle income countries (MIC):Cape Verde, Lesotho, Namibia, and South Africa others are low income countries(LIC). Water utilities covered are at national level for countries with single utility and at regional or provincial level for countries with many service providers in decentralized system.

Objectives and Topics
The primary objective of this work is to evaluate water and sanitation tariff structures across African utilities, specifically examining their impact on cost recovery, financial sustainability, and the effectiveness of cross-subsidies in achieving equity for different consumer groups.
- Analysis of tariff structure design and cost-recovery policies in African water utilities.
- Evaluation of efficiency through metering levels and price signals.
- Assessment of equity in connection charges and consumption-based billing.
- Performance benchmarking using a scorecard methodology for cost recovery and social equity.
- Comparison of African water tariffs against global regional standards.
Excerpt from the Book
2. An Overview of WSS tariffs in Africa
Water service costs include: 1. Initial infrastructure and connection cost and(fixed) 2. Operations and maintenance (O&M) and rehabilitation costs (variable). The common tariff structures in Africa are: 1. Metered water tariffs 2. Unmetered water tariffs 3. Nonresidential water tariffs 4. Waste water tariffs. Metered water tariff structure: In Africa, water metering is surprisingly widespread, with many utilities reporting 100 percent metering in their service areas. 9 utilities have implemented operating meters for all residential and nonresidential connections. For 35 utilities for which detailed information is available, the average metering ratio is 75 percent.
Types of block structures: Block tariffs are volumetric charges. Consumers must have a metered connexion to water services. They pay different amounts for different consumption levels. The water charge is set per unit (e.g. cubic meters) of water consumed and remains constant for a certain quantity of consumption (first block). The tariff shifts to the next block of consumption as water use increase, Block tariffs can be differentiated among consumer categories.
Summary of Chapters
Introduction: Provides the research scope, covering 45 utilities across 23 African countries, and defines the criteria for measuring tariff performance.
1 The conflicting goals of tariff design: Explains the dual necessity of delivering affordable services to consumers while maintaining an institutional system that ensures full cost recovery.
2 An overview of WSS tariffs in Africa: Details the various tariff mechanisms currently in use, including metered and unmetered structures, block tariffs, and the prevalence of O&M cost components.
3 Do tariffs recover costs?: Examines the financial sustainability of utilities and the role of government subsidies in covering operational shortfalls.
4 Do tariffs provide efficient price signals?: Discusses how metering and tariff structures influence consumer behavior and the necessity of water demand management in the African context.
5 Are tariffs equitable?: Analyzes whether current pricing policies protect low-income consumers and the fairness of connection charges relative to GNI per capita.
6 A scorecard of tariff performance: Presents a comparative assessment of utilities based on a multi-point criteria system involving equity, efficiency, and cost recovery metrics.
7 Conclusions: Summarizes the key finding that while many utilities succeed in O&M recovery, the equity objectives of increasing block tariffs are often not met, frequently burdening low-volume users.

Frequently Asked Questions
What is the primary focus of this research?
The work focuses on the evaluation of water supply and sanitation tariff structures in African utilities, specifically looking at how these tariffs balance cost recovery with equity and efficiency.
What are the central thematic fields covered?
The themes include tariff design goals, cost-recovery mandates, metering practices, price signals, equity in connection costs, and the usage of cross-subsidies within African water utilities.
What is the core research question?
The research seeks to determine whether existing African water tariffs effectively recover operational costs while ensuring equitable access for poor consumers and providing efficient market signals.
Which methodology is applied in this study?
The study utilizes a comparative analysis of 45 utilities across 23 countries, employing a scorecard system that awards points based on specific criteria for cost recovery, efficiency, and equity.
What topics are discussed in the main chapters?
The chapters cover the design of tariff structures (such as block tariffs), the financial performance of utilities, the impact of subsidies, and a comparative performance benchmarking against other global regions.
Which keywords best describe this research?
Key terms include water tariffs, cost recovery, increasing block tariffs (IBT), equity, water utility efficiency, and African infrastructure diagnostics.
Why are increasing block tariffs (IBT) often criticized in the study?
The study notes that IBT structures often have unintended consequences, as they may lead to low-volume consumers paying more, thereby failing to meet intended equity goals.
How do African utility tariffs compare to other regions globally?
African tariffs are generally higher than those in South Asia but remain somewhat comparable to averages in Latin America, largely due to high O&M costs in the African environment.
