It was built on the Vaitarna river in Thane's Kochale village in 2012. The dam stands at a height of 102 metres to impound 455 million litres of water vital for Mumbai's growing water demand. The city receives only 3400 million litres per day (Mld) compared to the 4000 Mld of demand. The water is expected to be transported to Bhandup treatment plant with a 40 km pipeline and delivered to the city.
Ghatghar Dam refers to two associated gravity dams built using roller-compacted concrete, the first use in India. They are situated in Ghatghar village in Ahmednagar district Maharashtra, India. Both dams create a lower and upper reservoir for the 250 MW pumped-storage hydroelectric power station. The upper Ghatghar dam is 15 m (49 ft) tall and on the Pravara River, a tributary of Godavari river. The lower Ghatghar dam is 86 m (282 ft) tall and located on the Shahi Nalla which is a tributary of Ulhas River to the south west of the upper reservoir in a steep valley. The hydro power project diverts Godavari river basin water outside the basin area to a west flowing river of Western ghats.
The power station is located between both the upper and lower reservoirs. During peak electricity demand hours, water from the upper reservoir turns two 125 MW reversible Francis turbine-generators. When energy demand is low, such as at night, the turbines reverse direction and pump water from the lower reservoir back to the upper. Construction on the project began in 1995, the dams were placed beginning in 2001 and were complete by 2006. The power station was commissioned in 2008.Upper Vaitarana Dam
Upper Vaitarana Dam, is an earthfill and gravity dam on west flowing Vaitarna river near Igatpuri, Nashik district of Maharashtra state in India. The reservoir created by this dam spreads on both Vaitarna and Godavari rivers catchment area.Vaitarna Dam
Vaitarna Dam, also called Modaksagar Dam, is a gravity dam on Vaitarna river which supplies water to Palghar,Mumbai, but located in Palghar & Nashik district in the state of Maharashtra in India. It was opened in 1957.
Another dam, the Middle Vaitarna Dam is to be built in the neighboring Palghar & Thane district on the same river; to supplement the water supply to the ever-growing needs of Mumbai and its metropolitan area.
