17. “A sustainable water-state” where there is “water for all, water for ever and more crops per drop” VISION AND PLANNING To store State's 25% average annual surface water resources by constructing 30 km long 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. KALPSAR YOJNA

18. To store State's 25% average annual surface water resources by constructing 30 km long 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. VISION AND PLANNING:

19. The Kalpsar Project envisages building a dam across the Gulf of Khambhat for establishing a huge fresh water reservoir for irrigation, drinking and industrial purpose. A 10 lane road link will also be set up over the dam, greatly reducing the distance between Saurashtra and South Gujarat . GENERAL INFO:

20.  In the  Gujarat State Gazette (Bhavnagar District)(1969) , there is a mention about construction of 25 mile long earthen dam and ten thousand feet long waste weir to prevent sea tide water ingress and store rain water. In 1975, Prof. E. M. Wilson of United Nation Mission presented a report to the Central Electricity Authority for construction of a dam between Ghogha and Dahej , with and without tidal power generation. History:

21. In August 1988, the  Central Electricity Authority  suggested to Government of Gujarat to construct two separate basins for tidal power and fresh water storage. In year 1988-89, M/s Haskoning of the Netherlands prepared a  Reconnaissance Report  of the Gulf of  Khambhat Development Project with different dam alternatives. In September 1986, the  Central Design Organization (CDO)  of Irrigation Department of Government of Gujarat prepared the design & estimate for constructing 46 km long dam to store 3377 MCM of water.

22. Benefits World’s largest man made fresh water reservoir in the  sea. Highest importance and priority to irrigation and drinking  water for Saurashtra and Central Gujarat regions. The Reservoir will have the storage more than double the Sardar Sarovar (Narmada Reservoir) capacity. 10.54 lakh ha land in 39 talukas of 6 districts of Saurashtra region will get irrigation benefit facility including rejuvenation of rivers. More than 60 existing dams will get permanently filled up with water.

23. Wind and solar energy will be generated which can also be used for lifting fresh water from the reservoir to the canal. Bhavnagar port will get revived which will result into speedy development of the region. There will be large saving in travel time and fuel due to reduction in distance by about 200 km between Bhavnagar to Surat -Mumbai.

24. Saline ground water of coastal area of Saurashtra & Central Gujarat will get converted into fresh water with reduction in soil salinity. Substaintial improvement in ground water quality as well as soil salinity of coastal area of Saurashtra & Central Gujarat. About 2 lakh ha land along the periphery of the reservoir will be opened up for development towards value-based land utilization. Enhanced benefit of world class industrial estate like Dahej and Dholera will be available to Bhavnagar/ Saurashtra region.
