The Project:KALPSAR YOJNA
The Gulf of Khambhat Development Project is mainly water resources project involving creation of fresh water reservoir in the Gulf of Khambhat for meeting demand of irrigation, domestic and industrial water supply. Associated components related to the fresh water reservoir are use of top of the dam across the Gulf as a surface transport link, potential development of fisheries, reclamation of saline land around the fresh water reservoir.
Objectives:
Gujarat is a water deficient State.It occupies 6.4 % of land area of the country and has 5% of the country's human population,but its surface water resource is only 2% of the country. The per capita per annum water availability is 990 cubic meter in the State which is much below the minimum requirement of 1700 cubic meter. Every year, 38000 million cubic meter average surface water is available in the State.However, even after including Sardar Sarovar Project (SSP), only 20480 million cubic meter (54%)is possible to store. There is no suitable site of land in the State, available for the creation of river valley project to store surplus / untapped above 40% surface water. In such a circumstance, the Gulf of Khambhat is an eligible option tocreat a reservoir by construction of a Gulf closure dam which can store about 10,000 million cubic meter water inflows of the rivers (Narmada, Dhadhar, Mahi, Sabarmati and some of the Saurashtra rivers), which accounts for 25% of total surface water resources of Gujarat. Creation of this fresh water reservoir does not involve any land acquisition or rehabilitation of people, and will serve as a life line of the Saurashtra region as well as an accelerator for the growing economic activities of Gujarat State.
The Gulf of Khambhat extends from north to south about 200 km and the width varies from 25 km at the inner end to 150 km at the outer mouth,covering an area of @ 17000 sq.km, of which only 2000 sq. km will be enclosed by constructing a dam across the Gulf between Bhavnagar and Dahej.
To store State's 25% average annual surface water resources by constructing dam across the Gulf of Khambhat. This reservoir will store about 10,000 MCM of surface water and will be the the world’s largest fresh water reservoir in sea.
