Sustainable Rural water-resource management continues to be a highly significant challenge in many rural parts of India, especially where severe shortages of water exist. The project is a participatory community based initiative for developing an unused well in Pichanur Panchayat, Coimbatore District, Tamil Nadu, as a productive source of sustainable water supply by integrating some rainwater harvesting methods. It addresses the persistent water deficiencies in the village and mitigates health and safety hazards from the abandoned well. The initiative is intended to replenish groundwater resources by harvesting rainwater from residential properties and converting the well for communal purposes, thereby aiding approximately 500 families, primarily from underprivileged Scheduled Caste (SC) populations. This project exemplifies the potential of affordable and scalable technical interventions to address water scarcity in rural areas, emphasizing the importance of community participation and long-term sustainability. This paper outlines the process of well renovation, the initiation of rainwater harvesting systems, and the governance role of local authorities in managing the infrastructure. The model can be replicated elsewhere in the rural context of water scarcity in order to promote holistic community-managed water systems appropriate for the attainment of SDGs on clean water and sanitation.
