Manual scavenging, the practice of manually cleaning, carrying, disposing of, or handling human excreta from dry latrines, sewers, and septic tanks, represents one of the most severe human rights violations persisting in modern society. This paper examines the harsh realities of manual scavenging through a human rights lens, with particular focus on South Asian countries where the practice remains prevalent despite legal prohibitions. Using mixed-methods research, the study analyzes socioeconomic factors, health impacts, and psychological consequences affecting those engaged in this practice. Our findings reveal significant gaps between legislative protections and ground realities, with continued discrimination, severe health hazards, and intergenerational poverty cycles. The research highlights the inadequacy of technological interventions without addressing underlying social stigma. The paper advocates for a comprehensive rights-based approach combining technological solutions, robust rehabilitation programs, and transformation of social attitudes to eliminate this dehumanizing practice.
