Summary of Technical Assistance Report: Supporting Impact Evaluation Studies in Water Supply and Sanitation in India (P144956)

Core Content

This report outlines the Technical Assistance (TA) initiative "Supporting Impact Evaluation Studies in Water Supply and Sanitation in India (P144956)" implemented by the World Bank's Water and Sanitation Program (WSP). The TA aimed to enhance the evidence base for policy decisions in the water and sanitation sector by supporting the design and implementation of impact evaluations and data-driven analytical work, as well as capacity building among government and project implementing agencies.

The report emphasizes the importance of rigorous impact evaluation in understanding the causal effects of water and sanitation interventions on health, welfare, and development outcomes. It highlights the limited exposure of India's water and sanitation sector to such methodologies and underscores the need for systematic analysis and evidence-based policy making.

Main Viewpoints

Impact Evaluation is critical for understanding the effectiveness of water and sanitation interventions.
The TA focused on two main areas: (i) Design and implementation of impact evaluations and (ii) Development of monitoring and information systems (MIS) and data collection tools.
Capacity building was a key outcome, with local institutions and project teams being actively involved in the process.
Data from existing surveys (e.g., MICS and DHS) was used to analyze the spillover effects of sanitation, particularly on child stunting.
The RCT methodology was employed where feasible, and quasi-experimental approaches were used in other contexts.

Key Information

I. Design and Implementation of Impact Evaluations and Data Driven Analytical Work

Functionality of Water Schemes: A concept paper was developed to define the multi-dimensional functionality of water schemes, including reliability, affordability, operation and maintenance, sustainability, and institutional aspects.
Kerala Study: A comprehensive evaluation of small rural water schemes in Kerala was conducted, comparing bottom-up (Jalanidhi) and top-down (KWA) approaches. The study found that Jalanidhi-I schemes performed 0.65 standard deviations better than top-down schemes.
Punjab Scoping Report: A scoping report was prepared to identify feasible activities for impact evaluation in Punjab, including social, technical, and financial audits, as well as an analysis of the impact of sanitation on health and education.
RCT in Punjab: The TA supported the design of a cluster randomized control trial (RCT) for evaluating the impact of sanitation interventions on child health and nutritional outcomes under the Second Punjab Rural Water Supply and Sanitation Project (P150520).
Sanitation and Stunting: Analytical work using data from Cambodia, Vietnam, and Sub-Saharan Africa demonstrated the spillover effects of sanitation on child height and stunting, showing that community-level sanitation significantly affects child health outcomes, even when individual households have improved facilities.

II. Development of Monitoring & Information System and Data Collection Tools

A web-based monitoring system (JIMS) was developed in Kerala, with enhanced features such as mobile survey systems, procurement, and financial modules.
Survey instruments for social, technical, and financial audits were created to facilitate data collection and analysis of performance of water schemes.
These tools can be customized and adapted for use in similar contexts and future studies.

III. Development of Institutional Capacity

The TA promoted collaboration between the World Bank, local agencies, and academics.
Workshops, seminars, and training programs were conducted to enhance the capacity of institutions to conduct impact evaluations.
Study instruments were developed to support sustainable water and sanitation systems, including cost recovery, operation and maintenance, and institutional sustainability.

Intermediate Outcomes

Enabling Monitoring and Evaluation: The development of a web-based monitoring system (JIMS) and survey instruments enabled more systematic and data-driven evaluation.
Enabling Policy: The findings from the TA informed policy refinement, particularly in understanding the impact of sanitation on child health and development.
Enabling Institutions: The TA increased the demand for evidence-based knowledge among state and central officials, promoting a culture of impact evaluation.

Conclusion

The TA was instrumental in building the capacity of local institutions and project teams to conduct rigorous impact evaluations in the water and sanitation sector. It highlighted the importance of spillover effects in sanitation and underscored the need for global knowledge sharing. The report calls for a larger regional or global activity to continue this work and expand the evidence base for policy formulation in water and sanitation in India.
