Having started in 1994, the Ghatagr Dams Project, due for completion in 2005, is the first major dam construction in India to use fly ash as a major constituent.

Funded by the Overseas Economic Cooperation Fund (OECF) of Japan, the £40 million Ghatghar Pumped Storage Scheme is also the first of its kind in the Maharashtra State being undertaken by the State Government's Irrigation Department.

The scheme involves the construction of two reservoirs. Both upper and lower reservoirs are constructed in Roller Compacted Concrete (RCC). This is the first time this method has been used in India. The water transmission system consists of an approach channel, intake structure and a pressure shaft that will take the water to the underground turbine house to feed two reversible units. The tailrace discharge from the turbine house is taken through the common tailrace tunnel to the lower pond.
