The document discusses rebuilding Bengaluru's urban water culture through digging one million wells across the city. It notes that Bengaluru receives around 970mm of annual rainfall, equating to 2500-3000 MLD of water, but currently extracts only 600 MLD, leaving room for increased groundwater recharge through additional wells. Some ways wells can be dug include in public storm drains, layouts, gated communities, apartments, and schools. Traditional well diggers called the Bhovi community can help map aquifers and spread awareness. The goal is increased groundwater recharge to reduce flooding and supplement water needs.
