Bengaluru's lakes are getting cleaner, but there is a catch, new study reveals what happens to the sewage after it is diverted

A new study published on July 30, 2026, shows Bengaluru’s lakes are getting cleaner due to diversion channels. While these channels keep local water clear, researchers found they do not treat sewage. Instead, the waste often moves downstream, meaning the city must consider the entire water system to fix pollution.
