Bangalore Water Supply and Sewerage Board

The Bangalore Water Supply and SewerageBoard (BWSSB) is responsible for providing potable water supply and managing sewerage services in the city of Bengaluru and its surrounding areas. It operates a network of treatment plants, pumping stations, reservoirs, and distribution pipelines that deliver water to residential, commercial, and industrial consumers. The board also oversees the collection, conveyance, and treatment of wastewater before its safe discharge or reuse. In addition to core utility functions, BWSSB handles customer billing, new connection processing, and maintenance of infrastructure assets.

As the sole agency mandated by the Karnataka government to manage water and sewerage in the Bengaluru metropolitan region, BWSSB holds a regulatory and operational monopoly over these essential services. Its service area covers one of India’s fastest‑growing urban centers, requiring continuous expansion of capacity to meet rising demand. The board’s technical team is tasked with monitoring system performance, implementing upgrades, and responding to operational incidents.

In April 2025, BWSSB faced an attempted cyber attack on its water connection portal, which was detected with assistance from CERT‑In and contained without compromise of sensitive customer data. Following the incident, the board migrated recent applicant data to more secure centralized servers, filed a formal complaint with cybercrime police, and began evaluating blockchain technology to strengthen portal security. This episode highlights BWSSB’s growing focus on cyber‑resilience as part of its broader mandate to safeguard critical public‑utility infrastructure.

BWSSB is a statutory board owned and funded by the Government of Karnataka, operating under the administrative oversight of the state’s urban development department. It does not have a private parent company or subsidiaries; its governance structure consists of a chairman, board members, and an executive director appointed by the state.
