Feasibility and sustainability of sewage treatment plants in Housing Schemes for low-income societies/communities: A case of Ahmedabad

Due to the population growth, consumption of water resources has increased and availability is reduced, so the demand for water is increasing rapidly. According to aqueduct water risk atlas most part of India falls under high water risk. This makes recycling and managing the water that runs through our households, industries, farms, and cities is necessary because the remaining fresh water is rapidly dwindling. Ahmedabad falls under high risk of water stress and there is a high dependency on ground water also.

The large wastewater treatment plants (STP) at city level are operating with limited capacity and reuse of treated used water is minimal due to absence of awareness among the users and policy makers. The pressure on city level sewage treatment plant is already high and will increase with future development. With objective to reduce the pressure on centralized wastewater treatment plants, the government has taken initiative for provision of sewerage treatment plant at society level as per GDCR. The new development schemes have STP provision also but most of the time it's in non-operational conditions after implementation. Also, the housing schemes implemented under low-income housing schemes has provision for sewage treatment plant but the plants are unused. At the end pressure remains on city level treatment plant only.

This DRP will focus on review the concept of sewage treatment plants in housing schemes for low-income societies/communities and identify the potential solutions/strategies to ensure working sewage treatment plant at society/community level.
