Water challenge in this location: The principal water challenges are related with: (i) scarcity of water as the water resources are far away from the city and demand-supply gap is increasing, (ii) space constraint for STP installation; need for compact plant design, (iii) Efficient sewage treatment is essential for promoting safe water reuse (iv) use of fresh water (surface and groundwater) for irrigation purposes (v) potential reuse of treated wastewater in the irrigation of current and new plots of land, thus, improving the living conditions of the population (access to safe food).
Benefits of the technology: The combination of robust and compact technologies for wastewater treatment (RBC and Sand filtration) and for water reclamation (Electrochemical disinfection) guarantees the safe reuse of the treated wastewater for irrigation purposes. Besides, the use of Electromagnetic treatment improves the physicochemical quality of the water that leads to an enhanced crops’ production. Further, as the RBC is closed tank aeration, it will be odourless. It will be able to handle shock load due to better aeration. It is cost effective. It will require minimal civil work and will be an automated process.
Potential for India: RBC is a technology that is compact and scalable and can be installed at land-constrained locations to recycle water at small scale. As outlined earlier there is in general a high demand in India for reliable and robust decentralized wastewater treatment plants.
Scope of replication and upscaling: The plant will be locally constructed with the involvement of BMC. Hence, excellent stakeholder visibility will greatly enhance the scope of replication within India.
