Summary of "Prioritizing Water Supply Infrastructure Investments in Sri Lanka: An Application of the World Bank Infrastructure Prioritization Framework"

Core Content

This paper applies the World Bank's Infrastructure Prioritization Framework (IPF) to prioritize water supply infrastructure investments in Sri Lanka. The goal is to support the National Planning Department (NPD) in making informed decisions about public investment in water projects, given the limited financial resources and the need to align with national development goals.

The IPF is a multi-criteria, quantitative framework that evaluates infrastructure projects based on social-environmental (SEI) and financial-economic (FEI) indicators. It aims to balance technical and policy considerations in infrastructure decision-making, ensuring that projects are selected based on a comprehensive set of criteria that reflect both economic and non-economic values.

The paper outlines the steps of the IPF implementation process, including criteria selection, data consolidation, indicator calculation, plotting against budget constraints, and project selection. It also presents the results of the prioritization exercise and discusses the implications for future infrastructure planning.

Main Viewpoints

• Resource Constraints: Sri Lanka faces significant challenges in infrastructure development due to limited public funds and a growing gap between infrastructure demand and supply.
• IPF as a Tool: The IPF provides a systematic, transparent, and objective method for infrastructure prioritization, incorporating both social-environmental and financial-economic factors.
• Multi-Criteria Evaluation: The framework uses composite indices (SEI and FEI) to evaluate projects, allowing for a nuanced comparison that goes beyond purely economic metrics.
• Policy Integration: The IPF is designed to align with national policy objectives, including poverty reduction, service quality, and environmental sustainability.
• Administrative and Political Feasibility: The prioritization process must be both technically sound and politically acceptable, balancing evidence-based decision-making with stakeholder input and institutional capacity.

Key Information

4.1.1. Step 1: Criteria Selection

• A set of 28 water supply projects were selected for prioritization.
• Criteria were chosen through stakeholder consultations, including the NPD and water sector experts.
• The SEI includes 8 criteria, while the FEI includes 2.
• Criteria for SEI include: new beneficiaries per $ invested, jobs created (direct), poverty level, bacterial water quality, water-borne diseases, continuity of supply, and existing safe water coverage.
• Criteria for FEI include: benefit-cost ratio and existing water resource yield.

4.1.2. Step 2: Data Consolidation and Preparation

• An initial list of 27 projects was considered, with two removed due to differences in project nature and two excluded due to insufficient data.
• Six new projects from the Public Investment Program (2016–2020) were added, bringing the total to 28.
• Data were collected from pre-feasibility studies and supplemented where necessary.

4.1.3. Step 3: Calculation of the Indicators

• The SEI and FEI were calculated using a combination of quantitative and qualitative data.
• The SEI was based on social and environmental factors, while the FEI focused on financial and economic aspects.
• The framework allows for flexibility in weighting criteria based on policy priorities and stakeholder input.

4.1.4. Step 4: Plotting SEI and FEI Results

• The results were plotted to visualize the trade-offs between social-environmental and financial-economic benefits.
• This visual interface helps decision-makers understand the relative merits of different projects.

4.1.5. Sensitivity Analysis

• A sensitivity analysis was conducted to assess the impact of different weighting scenarios on the prioritization results.
• The analysis highlights the importance of stakeholder input and the need for robust, adaptable criteria.

4.1.6. Step 5: Project Selection

• Projects were selected based on their composite scores, with a focus on maximizing social and environmental benefits within budget constraints.
• The IPF allows for the identification of a subset of projects that can be implemented with available resources, ensuring efficient use of public funds.

Way Forward

• The IPF can be integrated into the existing infrastructure planning process in Sri Lanka to improve the efficiency and transparency of project selection.
• It is recommended to apply the IPF to other infrastructure sectors as well, given its adaptability and comprehensiveness.
• The framework supports evidence-based decision-making, which is essential for public legitimacy and effective resource allocation.

Conclusion

The IPF offers a structured, multi-criteria approach to infrastructure prioritization that can help governments like Sri Lanka make informed, efficient, and equitable investment decisions. By incorporating both social-environmental and financial-economic considerations, the framework ensures that projects are selected not only based on their economic viability but also on their contribution to broader development goals. The application of the IPF to water supply projects in Sri Lanka demonstrates its potential to enhance infrastructure planning and support sustainable development.
