Access to potable drinking water reduces water-borne illnesses, improves health and productivity. CURE set up four water treatment plants as business enterprises in Delhi and Agra. The first, set up in Kalandar Colony, Delhi was imagined as a community-managed service to be sustained through user charges. The next two plants were set up in Savda Ghevra, Delhi as profit-making business enterprises managed by individuals. They treated groundwater and delivered it to homes. The fourth system was set up in the Trans Yamuna area of Agra. This was women operated and managed and aimed to replace the expensive and unsafe private tanker system with safe water. A women's business group was formalized to run the plant on a business model with doorstep supply. Supply stations were also set up inside settlements where people could come and collect water. Water Kiosks as community businesses have many challenges - land, location, transportation, quality of groundwater and very high maintenance cost.
