Abstract


In populated cities with many slums and migrant population there is groundwater stress and wetland encroachment.The proposed intervention in two cities Kolkata and Guwahati in India provides a sustainable solution for drinking water, sanitation and hygiene along with farming opportunities for slum dwellers. The integrated 12 KVA off-grid solar-water plants that provides lighting facility and dispenses daily up to 10,000 Litres of WHO standard drinking water to 600 households uses wetlands as water source. It showcases complete community governance for equitable distribution of energy and water through Water-Energy Automated Dispensing Machines’ using RFID cards and assures complete hygiene in the area flushed with the rebuff water. The intervention generates biomass energy and organic manures from the refusals of bio-toilets and municipal waste. Developing community governance for wise use of energy and water resources through participatory resource budgeting and management to reduce climate footprints towards sustainable consumption and production is the core component of the project. Water is priced at USD 0.008 for slum dwellers and sold to outsiders at USD 0.02 per litre. The earnings record on average USD 250 per month and is saved for operation and maintenance. Perusal of results show that the sustainable model with a break even period of 45 months not only provides the basic amenities of life for the urban poor but the co-benefits were also improved health and sanitation, conservation of the wetland and the preservation of dignity for the entire community.
