According to a press release, a long-term plan will consider current requirements and the projected increase in sewage volumes by 2047. Ashok Reddy also ordered a comprehensive survey of private STPs at hotels, commercial complexes, high-rise buildings and residential complexes in the lake’s catchment.

He directed officials to expedite ongoing desilting, pipeline connectivity and sewage diversion works. They were also asked to examine an alternative diversion system to prevent sewage from flowing back towards colonies when an STP was not functioning, or inlet routes were blocked.
