BIAL Sewage Treatment Plant - Airport Wastewater Management in Bengaluru, India

The BIAL Sewage Treatment Plant is located near Kempegowda International Airport in Bengaluru, Karnataka, India. It serves the airport's wastewater treatment needs, handling sewage from the airport facilities and surrounding areas. The plant is operational and plays a key role in managing the region's wastewater. As a treatment facility in India, it operates under the national environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. These frameworks mandate treatment standards for wastewater discharge to protect water bodies. The plant's treatment processes are designed to meet these regulatory requirements. The treated wastewater is likely discharged into local water bodies or used for non-potable purposes such as landscaping or cooling. The region's drainage ultimately flows into the Pennar River basin or the Cauvery River basin, depending on the exact location. Proper treatment helps protect downstream ecosystems and supports water reuse in water-scarce areas.

The plant is situated in the semi-arid Deccan Plateau region of Karnataka. Treated effluent likely enters local streams that drain into the Pennar River or the Cauvery River, both of which are important for agriculture and drinking water supply. The area faces water scarcity, making wastewater treatment and reuse critical for sustaining local water resources and protecting downstream aquatic habitats.
