Summary of "Reforming Urban Water Utilities in Western and Central Africa: Experiences with Public-Private Partnerships"

Core Content

This report analyzes the experiences of public-private partnerships (PPPs) in urban water utilities across Western and Central Africa, focusing on their impact, performance, and lessons learned. It presents 15 case studies from 11 countries, including both water supply and combined power/water utilities, to evaluate the effectiveness of PPPs in improving access, reliability, affordability, and financial sustainability of water services.

Main Points

Overview of PPPs in the Region

• Western and Central Africa has one of the longest experiences with PPPs in the developing world, particularly in water supply and combined power/water utilities.
• Côte d'Ivoire has a successful partnership dating back to 1959, while Senegal's began in 1996.
• Over the past two decades, 15 countries (out of 23 in the region) have experimented with PPPs.
• The total served population across all PPPs exceeds 29 million.

Types of PPPs

• Long-term concessions: Implemented in Gabon, Cape Verde, and Mali for combined power/water supply utilities.
• Medium-term afternage contracts: Used in Côte d'Ivoire, Senegal, Niger, Guinea, Central African Republic, and Cameroon for water supply, and in The Gambia for combined power/water.
• Short-term management contracts: Mostly in combined power/water utilities, including Chad, Guinea Bissau, Sao Tome, and Gabon.
• Alternative performance-based approaches: Burkina Faso's case is highlighted as an example of improving public utility operations through service contracts without full management delegation.

Performance of PPPs

• Successes: Five PPPs have been considered successful, including Côte d'Ivoire, Senegal, Niger, Burkina Faso, and Gabon. These have led to improved access, reliability, and affordability.
• Mixed outcomes: Three PPPs have shown some improvements but ultimately ended in termination or reversion to public management.
• Failures: Five PPPs have failed to significantly expand access or improve efficiency, often due to financial or operational challenges.
• Too early to judge: Two recent PPPs in Ghana and Cameroon are still under evaluation.

Key Impact Areas

• Access to piped water: PPPs have contributed to expanding access, especially through residential connections.
• Reliability and quality: Private operators have improved service continuity and water quality.
• Operational efficiency: Private operators have achieved significant gains in reducing water losses, improving bill collection, and increasing labor productivity.
• Financial sustainability: Successful PPPs have managed to reduce financial risks and improve cost recovery through efficient operations and supportive policies.

Key Lessons Learned

Sector Reforms and Governance

• Successful PPPs are part of well-designed sector reforms, which include clear policies, regulatory frameworks, and financial strategies.
• Governments must comply with their policy commitments, such as allowing tariff adjustments and paying water bills.
• The presence of a private operator has encouraged compliance with these commitments.

Role of Private Operators

• Private operators have been instrumental in improving service quality and financial sustainability.
• They have introduced operational efficiency and cost recovery strategies that have benefited customers and utilities alike.

Social and Financial Inclusion

• Social connection programs for poor households have been a major success factor, enabling rapid expansion of the customer base and affordability.
• Donor funding has played a significant role in supporting infrastructure rehabilitation and expansion.

Regulatory Framework

• Regulation by contract has generally been more effective than regulation by an independent body in the region.
• Independent regulatory agencies often lack clarity, tools, and capacity, making contract-based regulation more practical.

Local Partnerships

• Successful PPPs are implemented by local partners, indicating the importance of local ownership and management.
• The transfer of ownership and management to local investors and managers has been a key feature of the most successful PPPs.

Looking Forward

• A flexible and resilient regional PPP model has emerged, particularly the "African Affermage" approach.
• This model allows for gradual cost recovery and financial sustainability, with the public partner managing the financial risks and the private partner focusing on operational efficiency.
• The involvement of local private operators has increased, suggesting a move towards more regional and South-South collaboration.
• Continued commitment from both public and private stakeholders is essential for the long-term success of PPPs in the water sector.

Key Takeaways

• PPPs have shown mixed results in Western and Central Africa, with some successes and many challenges.
• The aftermage model has been particularly effective in the region, allowing for gradual and socially acceptable cost recovery.
• Successful PPPs rely on clear policies, local ownership, and effective regulation.
• Donor support and social connection programs have been crucial in enhancing financial viability and service expansion.
• The future of PPPs in the region depends on continued collaboration, commitment, and adaptability.
