Water Security Sectoral Guide GCF Water Project Design Guidelines Part 3

The GCF Water Project Design Guidelines Part 3 outlines a framework for creating climate-resilient sanitation (CRS) projects. It details how climate hazards like flooding, sea-level rise, and drought impact sanitation infrastructure and services, and provides a scientific basis for both adaptation and mitigation. The guide advocates for a paradigm shift toward transformative sanitation planning, emphasizing circular economy principles—such as the recovery of water, nutrients, and energy—to reduce greenhouse gas emissions and enhance community resilience. It provides specific technical interventions for the entire sanitation service chain and outlines the requirements for successful GCF funding proposals, including alignment with investment criteria and national climate strategies.

• Climate change significantly threatens sanitation systems through various hazards: floods can cause "backflows in sewer systems" and "direct physical damage" to infrastructure; sea-level rise leads to "corrosion of pipes, pumps and valves" and groundwater rise; and droughts cause "blockages, overflows, and increased maintenance requirements" due to reduced water availability.
• Sanitation is a significant source of greenhouse gas (GHG) emissions, primarily through the anaerobic decomposition of organic matter in pits, tanks, and treatment plants, which releases methane (CH4). In Kampala, a 2022 study estimated that "almost 50% of the city’s GHG emissions are from sanitation".
• Poorly managed sanitation causes eutrophication in aquatic environments, which increases GHG emissions and degrades carbon-sequestering ecosystems. For example, "88% of seagrass ecosystems are exposed to wastewater", and the resulting degradation can release large amounts of CO2 as sediment is exposed to oxygen.
• The GCF promotes a paradigm shift toward "Transformative sanitation planning and programming for climate-resilient sanitation" integrated into national and regional plans. This approach focuses on two key outcomes: "Climate-resilient infrastructure and services" and "Circular economy and integrated management".
• Circular economy strategies can mitigate climate change by substituting high-impact inputs with recovered resources: treated wastewater can reduce freshwater extraction, recovered nutrients can offset "synthetic fertilizers with their high carbon footprint", and biogas can replace carbon-intensive energy sources.
• Adaptation interventions across the sanitation service chain include technical modifications such as "Raised latrines" to prevent overflow, "Simplified sewers" for water-scarce areas, and "Modular Treatment Plants" that can adjust to flow variations during droughts.
• To enable climate-resilient sanitation, the document recommends strengthening Policy, Institutional, Regulatory, and Financing (PIRF) mechanisms, including aligning projects with "Nationally Determined Contributions (NDCs), National Adaptation Plans (NAPs)" and creating regulatory frameworks that encourage private sector investment.
• Successful GCF proposals must demonstrate alignment with six investment criteria: "Impact potential", "Paradigm shift potential", "Sustainable development potential", "Needs of the recipient", "Country ownership", and "Efficiency and effectiveness".
