Summary of "Performance of Water Utilities in Africa"

Core Content

This report, authored by Caroline van den Berg and Alexander Danilenko, evaluates the performance of water utilities across Africa using a panel dataset of 120 utilities from low- and lower-middle-income countries. It analyzes operational, financial, and customer performance metrics and explores the institutional and economic factors influencing utility performance. The report also includes case studies of selected utilities and provides policy insights to support the achievement of the Sustainable Development Goals (SDGs) related to water and sanitation access.

Main Points

1. Overview of Water Utility Performance in Africa

• Africa's urban population grew by over 80% between 2000 and 2015, reaching 373 million.
• Despite increased access to piped water, the proportion of urban dwellers with piped water on premises declined from 40% to 33%.
• Water utilities in Africa generally show weak performance, though some operate relatively well.
• The report highlights the need for substantial investment in water and sanitation services to meet SDG targets.

2. Performance Analysis

• Operational Performance: Measured by non-revenue water (NRW), labor efficiency, and cost per cubic meter (m³).
• Financial Performance: Assessed using operating cost coverage ratio (OCCR) and revenue sufficiency.
• Customer Performance: Evaluated based on service quality, reliability, and affordability.
• The performance of utilities is highly variable, both within and across countries, due to local factors and national policies.

3. Composite Performance Index

• A composite index was developed to evaluate the overall performance of utilities by combining operational, financial, and customer performance.
• The index shows that African utilities are generally underperforming compared to global benchmarks.
• Utilities with a regulator tend to perform better in customer service but not necessarily in financial or operational performance.

4. Drivers of Utility Performance

• Economic Development: Has a positive effect on water coverage and customer performance.
• Regulation: Plays a role in improving customer performance but not in operational or financial performance.
• Service Delivery Models: District- or municipal-based models show better customer performance, but coverage is still limited.
• Scale and Scope: Larger utilities tend to have higher performance, but there is a point of diminishing returns. Economies of scope are evident when utilities provide both water and wastewater services.
• Data Quality: Is critical for assessing performance and guiding sector planning.

5. Case Studies

• The report includes case studies of five African utilities: ONEA (Burkina Faso), SODECI (Côte d'Ivoire), NCWSC (Kenya), SDE/SONES (Senegal), and NWSC (Uganda).
• These case studies reveal that even well-performing utilities face challenges in service quality and affordability.
• Cross-subsidies and tariff structures are important factors in service delivery and affordability.

6. Key Findings and Recommendations

• Affordability and Cost Recovery: There is a need to balance cost recovery with affordability to avoid increasing government subsidies.
• Investment Requirements: Significant investments are required to expand water coverage, especially in Sub-Saharan Africa.
• Governance and Regulation: Improved governance and regulation can enhance utility performance, particularly in customer service.
• Data and Transparency: Reliable data is essential for performance evaluation and strategic planning.
• Sector Reforms: Combinations of sector reforms and economic improvements can lead to better utility efficiency.

Key Information

• Non-Revenue Water (NRW): A major indicator of operational inefficiency, with significant variation across utilities.
• Operating Cost Coverage Ratio (OCCR): Used to assess financial performance, with many utilities failing to cover their O&M costs.
• Affordability: Median affordability levels vary, and improving it requires careful policy design.
• Economies of Scale and Scope: Suggest that larger and more integrated utilities may perform better.
• Government Role: Governments often bear the cost of O&M and expansion, which can limit investment in new connections.

Conclusion

The report underscores the challenges faced by African water utilities in achieving sustainable and equitable service delivery. While some utilities perform better than others, overall performance remains weak. The findings emphasize the importance of effective governance, regulation, and economic management in improving utility performance. It also highlights the need for large-scale investments and better data collection to support the growth and development of the water sector in Africa, particularly in the context of rapidly urbanizing populations and the pursuit of SDG targets.
