recharging the ground water table.-bangalore

Every raindrop that fall on Bangalore roads will only go down the drain. But every drop that falls on the Metro corridor ends up recharging the ground water table.

Bangalore Metro Rail Corporation (BMRC) is one of the urban utilities to have adopted rain water harvesting in a massive and practical way. The Metro has made simple arrangements to catch all the rainwater that falls on its station areas and use the same for various non-potable uses.

Each of the six stations on the Metro's operational stretch between MG Road and Byappanahalli have water tanks of one lakh litre capacity each, to store the rain water. "We make use of this for construction, landscaping and maintenance. The water collected on the tracks further enters the ground water chamber, which we can't quantify," said BMRC officials.
