The new Gargai dam, planned by the BMC, is located near the Modak Sagar dam, which has received the highest rainfall among major dams over the last five years, ensuring that the Gargai dam will also benefit from substantial rainfall. A 2-km tunnel could connect the new dam with Modak Sagar, enabling BMC to link the Gargai supply to Modak Sagar`s existing infrastructure, which is already operational to supply water to Mumbai. The proposed Gargai project is situated in Palghar, 110 km north of Mumbai.

With an estimated cost of Rs 5,000 crore and a construction period of five years, the BMC has high expectations from the dam as the city`s water demand continues to outpace supply. Saurabh Deshpande, an assistant engineer from the Water Supply Department, said, “The Gargai dam is near Modak Sagar, which generally receives the highest rainfall. This will ensure that the new dam also gets good rainfall.”
