The link envisages transfer of balance available water at the proposed Bhugad reservoir across Damanganga river and at the proposed Khargihill reservoir across Vagh river, a tributary of Damanganga river, in Damanganga basin for augmentation of water supply to Greater Mumbai to meet its domestic and industrial water requirements in the near future. The Bhugad and Khargihill reservoirs (proposed by NWDA) and Pinjal reservoir (proposed by Government of Maharashtra across Pinjal river, a tributary of Vaitarna river) are proposed to be connected through pressure tunnels. The purpose is to make the combined water from Bhugad and Khargihill reservoirs to reach Pinjal reservoir from where further arrangements for transmitting the water to Greater Mumbai will be made by Municipal Corporation of Greater Mumbai (MCGM) and Mumbai Metropolitan Region Development Authority (MMRDA)[6]. The salient details of Damanganga-Pinjal link project are briefly described below:  A 826.60 m long composite dam is proposed on Damanganga river near village Bhugad in Peint taluka of Nasik district of Maharashtra State and very near to border of Valsad district of Gujarat. The FRL, of the dam fixed on the basis of detailed Surveys & Investigations at 163.87 m. The gross and live storage capacities of the storages are 426.39 Mm3 and 400.00 M m3 respectively. The maximum height of dam is 68.63 metres.  A 16.85 km long Bhugad-Khargihill link tunnel with 5.0 m diameter connecting Bhugad and Khargihill reservoirs below their minimum draw down levels (MDDLs)is proposed.  A 572.80 m long composite dam across river Vagh at Khargihill site near village Behadpada in MokhadaTaluka of Thane district of Maharashtra State is proposed. The FRL, of the dam fixed on the basis of detailed Surveys & Investigations at 154.52 m. The gross and live storage capacities have been fixed as 460.79 Mm3 & 420.50 Mm3 respectively. The maximum height of dam shall be 75.62m.  A 25.70 km long Khargihill-Pinjal link tunnel with 5.25 m diameter connecting Khargihill and Pinjal reservoirs below their MDDLs.  A 681 m long Pinjal dam on river Pinjal (tributary of Vaitarna river) near village Khidse in Jawhar taluka of Thane district has been proposed by Govt.of Maharashtra. The FRL, have been fixed on the basis of detailed Surveys & Investigations by Government of Maharashtra as 141.00 m. The gross and live 1532
