Environmental & Social Impact
24
 Minor environmental impacts only during construction
period i-e; air pollution due to heavy construction traffic,
blasting
 No significant social impacts besides relocation of some
houses, 7 km road in reservoir area, some shops and roads,
side restaurants, WAPDA grid station and Azad Pattan
Bridge
 Above mentioned impacts are too small therefore making
project more feasible and attractive

Conclusion
29
 No logistical problems due to easy project approach
 Project location is close to the national grid system
and load center ,hence there will be no problem in
power dispersal
 Project completion time is approximately 4.5 years.
 No significant environmental and social impact.Run
of the river project.
 Facts and figures brought out in this presentation
lead to ascertain that Karot HPP is an economical
and ESI free proposition compared to other such
