Analyzing Sanitation Sustainability Assessment Frameworks for Resource-Limited Communities

Area of Science:

• Environmental Science
• Public Health
• Sustainable Development

Background:

• Numerous sanitation sustainability assessment frameworks exist, aiming to improve safe sanitation services, particularly in resource-limited settings.
• Despite framework development, many remain unused, and high sanitation system failure rates persist globally.
• Understanding framework definitions, measurement indicators, and their effectiveness is vital for achieving sustainable development goals in sanitation.

Purpose of the Study:

• To analyze and evaluate existing sanitation sustainability assessment frameworks.
• To identify commonalities and discrepancies in framework definitions and indicators.
• To assess the advantages and disadvantages of different frameworks in evaluating sanitation system success and failure.

Main Methods:

• A subset of sanitation sustainability assessment frameworks was reviewed.
• Frameworks were applied to evaluate both successful and failed community sanitation systems in India.
• Analysis focused on framework definitions, core indicators, data collection guidance, and differentiation capabilities between system outcomes.

Main Results:

• Evaluated frameworks lacked a shared definition of sanitation sustainability and a core set of essential indicators.
• Many indicators lacked clear definitions and guidance for data collection and analysis.
• Framework effectiveness in differentiating successful from failed sanitation systems varied significantly.

Conclusions:

• Improvements are needed, including indicator pilot testing, context-specific weightings, and project-specific framework selection.
• Clarifying and enhancing assessment frameworks can improve their effectiveness and adoption.
• Enhanced frameworks can lead to better decision-making, improving public health, environmental quality, economic viability, and sanitation acceptance.
