Bangalore Water Supply and Sewerage Board

The Bangalore Water Supply and Sewerage Board (BWSSB) is the public utility responsible for providing potable water supply and managing sewerage services in the Bengaluru metropolitan area. It operates under the name Bangalore Water Supply and Sewerage Board, also known by its Kannada abbreviation ಬೆಂಗಳೂರು ನೀರು ಸರಬರಾಜು ಮತ್ತು ಒಳಚರಂಡಿ ಮಂಡಳಿ. The board's core activities include sourcing water from reservoirs and groundwater, treating it to drinking standards, and distributing it through an extensive network of pipes to residential, commercial, and industrial consumers. Simultaneously, it collects wastewater via sewer lines, treats it at sewage treatment plants, and disposes of or reuses the effluent in accordance with environmental standards. BWSSB serves the city of Bengaluru and its surrounding urban agglomerations, which constitute a major economic and population centre in southern India.

As a statutory body established by the Government of Karnataka, BWSSB exercises regulatory authority over water and sewerage infrastructure within its jurisdiction. The organisation is recognised for its specialised focus on integrated water resource management, combining supply, treatment, and sanitation services under a single administrative framework. In addition to enhance the security and transparency of its digital platforms, as noted after a cyber incident in April 2025. On 11 April 2025, the board reported an attempted cyber attack on its water connection portal that was detected and contained by its technical team following an alert from the national cyber response agency. Investigators confirmed that no sensitive customer data was compromised, although a limited amount of non‑sensitive information was accessed, prompting the transfer of affected data to more secure centralised servers. The incident led to a formal complaint with the cybercrime police and reinforced BWSSB’s commitment to continuously upgrading its systems to maintain service security. These actions underscore the board’s role as a critical public service provider that must balance operational resilience with technological innovation.
