Did you know that the Bangalore Water Supply and Sewerage Board (BWSSB) is using treated wastewater from the city's sewage treatment plants to recharge groundwater in the drought-affected districts of Kolar, Chikkaballapur, Ramnagara etc - the world's second largest program of its kind?

"It's not a lack of water, but a lack of imagination," says S Vishwanath, our guest on this episode of The Boring Climate Podcast.
