The document proposes separating the islands of Mumbai to address the city's flooding problems. It discusses how Mumbai was formed by joining seven islands, which has led to drainage issues. The Mumbai Megaproject plan involves widening existing drainage channels between the islands from 15-20 meters to 100-150 meters. Where channels have been filled in, new ones would be dug to separate the islands and allow rainwater to drain. This would solve Mumbai's flooding problems. The plan also includes building dykes and barriers along the coast to protect from rising sea levels. The project is intended to be self-financing and could fund other development projects in Maharashtra. More details would be shared with government and project partners following legal processes.
