After undergoing one of the worst water crisis in its history, Chennai bounced back to come up with milestone projects that could make the city water secure in the long run.

With the four major reservoirs that supply drinking water to Chennai going bone dry and deficit rains during 2018, the city’s water supply was reduced 525 million litres a day (mld). It was one of the first Indian cities to run dry early this year.

As taps stopped flowing and water became a premier commodity, residents looked deeper into the ground and sunk borewells up to a depth of 600 feet. In June, the average groundwater table in the city declined by a staggering nine metres.
