Have we learned nothing 20 years after 2005 floods? TOI travels along Mumbai's Mithi river

Two decades after the great flood of 2005 revealed the importance of the Mithi, a journey down the river shows that the restoration of this vital waterway remains incomplete. And along the banks, concrete is rising—a sign that the lessons of 26/7 have not been fully absorbed.
Near the start of this 18-km river, at Filterpada, improvements are visible. Slums have been cleared for a retaining wall and service road that lets cleaning machines access the river. A sewer line has been laid to run sewage water to a new treatment plant at Powai, where the water is cleaned and discharged back upstream.
