Climate-resilient WASH infrastructure (India)

This research explores the implications of climate change on Water, Sanitation, and Hygiene (WASH) infrastructure in Kochi, India, a city vulnerable to extreme weather events due to its coastal location and high population density. Changes in monsoon patterns contribute to floods and droughts, affecting water and sanitation facilities. Sea-level rise leads to saltwater intrusion into groundwater, rendering it unfit for consumption. The study assesses the current WASH infrastructure in Kochi and anticipates the impact of climate change on its resilience. Field visits and stakeholder engagements inform the identification of five locations facing significant challenges. The research aims to develop a climate-resilient sanitation strategy for Kochi, emphasizing a comprehensive approach covering the entire sanitation value chain. Recommendations include crisis-responsive measures, capacity building for sanitation system upgrades, and long-term goals like managed retreat to safeguard sanitation assets in the face of climate change. Implementing these strategies can enhance urban resilience and ensure continuous access to safe sanitation services amidst climate-related challenges.
