ADBI Policy Brief No. 2024-11 (June): Local Private Sector Involvement in Public-Private Partnerships for Sustainable Water and Sanitation in Asia

Key Points

1. PPP Definition and Models

   • Public-Private Partnerships (PPPs) are an alternative to traditional public infrastructure procurement methods.
   • PPPs involve various contract types and models, emphasizing private sector engagement while acknowledging the government's role.
   • Models range from operational management to asset concessions, varying by asset ownership, service provision, and risk transfer.

2. Importance of Contextual Appropriateness

   • PPPs should only be implemented if the local context is prepared and they are guaranteed to improve service delivery.
   • Successful implementation requires strong local government capacity, supportive regulations, clear risk allocation, and accountability.

3. Japan’s Experience

   • Japan emphasizes localization in PPPs, with 85% of PPPs at the local level.
   • Japan uses a mix of models: BTO (build-transfer-operate), outsourcing, and recently concessions.
   • Success examples include Hamamatsu's 20-year sewerage concession, which reduced costs and improved revenue.
   • Challenges include regulatory limitations, funding primarily from public sources, political sensitivities around tariffs, and technical infrastructure issues.

4. PPPs in Developing Asia

   • Success varies; even in Japan, outcomes depend on regulatory frameworks and operational environments.
   • Key challenges include inadequate regulatory frameworks, unclear responsibility sharing, and difficulty securing long-term private investment.
   • Success criteria include proper positioning of PPPs, stakeholder engagement, tariff regulation, and project feasibility.

5. Steps for Success

   • Step 1: Position PPPs within water and sanitation projects by understanding specific needs and objectives.
   • Step 2: Engage stakeholders effectively, ensuring clear communication and coordination.
   • Step 3: Secure supply sustainability through solid regulations for tariff setting and adjustment.
   • Step 4: Plan and execute PPPs carefully, avoiding pitfalls by defining clear terms and conducting thorough feasibility studies.

Conclusion

• PPPs offer a viable solution for enhancing water and sanitation services but must be implemented in a context-specific manner to address regional challenges.
• Effective stakeholder engagement and regulatory frameworks are critical for success.
