Bengaluru to Reuse Wastewater for Crops

Karnataka's horticulture department is implementing a plan to supply scientifically treated wastewater for horticultural crops in peri-urban areas of Bengaluru and other growing cities. This initiative aims to address concerns about vegetables and leafy greens being cultivated using polluted water, a practice exacerbated by water shortages. The department will collaborate with the Bangalore Water Supply and Sewerage Board and Karnataka Urban Water Supply and Drainage Board to establish additional sewage treatment plants.

This new proposal seeks to create a reliable network for supplying tertiary-treated wastewater that meets agricultural safety standards. The recycled water will irrigate vegetables, fruits, and flowers, reducing reliance on freshwater and preventing farmers from using contaminated sources. This approach differs from the KC Valley Project, which primarily focuses on groundwater recharge.

The project draws inspiration from the successful use of treated wastewater for irrigation in Bengaluru's Lalbagh Botanical Garden and Cubbon Park. Officials believe this model can be replicated across urban centers in Karnataka, offering a dependable irrigation source for horticulture farmers, improving crop productivity, and enhancing consumer safety.
