Damanganga – Pinjal Link Project will
augment domestic water supply of Mumbai
city. The population of Mumbai city as per
census of the year 2011 is 1.84 crores. In
addition, the villages lying in the
periphery/vicinity of the reservoirs and
villages developed for settlement of PAPs
will also get drinking water supply to an
extent of 10 Mm3(for both Domestic and
Industrial use) from these two reservoirs.
895 Mm3 (210 Mm3 from Bhugad dam; 369
Mm3 from Khargihill dam; and 316 Mm3
from Pinjal dam)
Diverted water will be used to augmentation
of domestic water supply of Mumbai city
The project envisages providing 10.0 Mm3 of
water to meet the water requirements of the
population in the vicinity of the reservoir for
various uses including industrial purpose.
