Sangam Vihar, an unplanned settlement in Delhi, is experiencing severe water scarcity. The government's Master Plan for 2041 does not address solutions for settlements like Sangam Vihar. A study by the Centre for Science and Environment suggests that decentralized management and retrofitting infrastructure could improve water supply, sanitation, and stormwater management. The majority of septic tanks in Sangam Vihar are unlined, posing a risk of fecal matter leaching into the ground. The area is undergoing a change with a centralized sewer system being constructed, but the high population density may pose challenges. The CSE proposes decentralizing water supply, combining sanitation systems, and planning for stormwater management as potential solutions. [Extracted from the article]
