Fecal Sludge Management: Diagnostics and Guidelines for Service Delivery in Poor Urban Areas

Core Content

This report, authored by the World Bank, provides an overview of fecal sludge management (FSM) in poor urban areas and outlines diagnostic tools and policy recommendations to improve service delivery. It is based on fieldwork conducted in five cities: Balikpapan (Indonesia), Dhaka (Bangladesh), Hawassa (Ethiopia), Lima (Peru), and Santa Cruz (Bolivia).

Main Points

1. Urban Sanitation Context

• Urban sanitation remains a major challenge in low- and middle-income countries.
• The urban population in Least Developed Countries (LDCs) has more than tripled between 1990 and 2015.
• Access to sanitation has improved in relative terms, but absolute numbers of people using unimproved sanitation have increased.
• Under the post-2015 Sustainable Development Goals (SDGs), there is a focus on the entire sanitation service chain, from containment to disposal.
• Universal access to toilets is not sufficient; safe management of excreta along the entire chain is also required.

2. Fecal Sludge Management (FSM)

• FSM involves the emptying, conveyance, treatment, and disposal of fecal sludge from on-site sanitation systems.
• Non-networked sanitation is the norm in many developing countries, especially among the poor.
• These systems often result in fecal sludge being a mix of raw or partially-digested feces and urine, along with contaminated wastewater, solid waste, and other materials.
• FSM services are often underdeveloped, with limited quality and access to services for sludge removal and treatment.

3. Diagnostic Tools

• Three key diagnostic tools were developed:
  • Fecal Waste Flow Diagram (SFD): Maps the flow of fecal waste and identifies where it is managed or not.
  • City Service Delivery Assessment (CSDA): Evaluates the enabling environment and service quality.
  • Prognosis for Change (PFC): Analyzes political and economic factors that may block or enable FSM progress.
• Two decision-support tools:
  • Service Delivery Action Framework: Guides action based on the enabling environment.
  • Intervention Options Assessment: Helps identify technical interventions for the service chain.

4. Case Studies

• Five cities were selected to test the tools in real-world settings.
• Each case study provided quantitative and qualitative data on FSM and related sanitation services.
• The studies also contributed to initial recommendations for future interventions.
• Summaries of each case study and a synthesis of lessons learned are included in the report.

5. Policy Recommendations

• Inclusion of FSM in national policy and legislation is essential for effective service delivery.
• Incentives for the private sector are needed to support affordable and safe FSM services.
• Groundwater protection should consider all sanitation options, not just sewerage.
• Institutional, regulatory, legal, and financial arrangements must be in place to support FSM.
• Planning for incremental change is necessary, as sewerage is not always immediately feasible.
• Equity in subsidies is important to ensure that poor FSM users are included in sanitation service delivery.
• Community engagement and complementary roles between utilities, local governments, and the private sector are critical for success.
• Technical innovations and better political economy analysis tools are needed to address knowledge gaps.

Key Information

• Fecal sludge is a highly variable mixture of feces, urine, and contaminated wastewater.
• Non-networked sanitation is common, especially in slums and informal settlements.
• Manual emptying is prevalent but not sustainable due to land use changes and cost issues.
• Improved water supply can lead to the adoption of manual or cistern flush toilets, which are cheaper to empty than to rebuild.
• Groundwater contamination is a concern, and sewerage alone may not be effective without an integrated urban water management (IUWM) approach.
• FSM is part of the broader urban sanitation agenda, and its integration is necessary for achieving SDG targets.

Conclusion

This report emphasizes the importance of FSM in achieving safe and inclusive urban sanitation. It highlights the need for policy integration, institutional capacity, financial mechanisms, and community involvement. The diagnostic tools and case studies provide a practical framework for assessing and improving FSM services in poor urban areas.
