  1. PRESENTATION ON GULF OF KHAMBHAT DEVELOPMENT PROJECT(WR) Kalpasar as a prospective Water solution - Saurashtra A Truly Matchless Project

  2. MISSION

  3. VISION To create world’s largest fresh water reservoir in sea, by constructing 30 km long dam in the Gulf of Khambhat, to store more than 10,000 MCM of surface water, i.e. 25% of volume of State’s average annual rain water inflow.

  4. Per Capita Availability of Water Per Capita Availability of Water (Year 2001) 730 m3/Annum North Gujarat 343 m3/Annum Kutch PALANPUR RANN OF KUTCH MEHSANA LITTLE RANN Bhuj GANDHINAGAR AHMEDABAD Saurashtra GODHRA KHEDA 540 m3/Annum SURENDRANAGAR VADODARA JAMNAGAR RAJKOT BHAVNAGAR Central & South Gujarat AMRELI BHARUCH JUNAGADH SURAT 1880 m3/Annum DANG VALSAD Note : As per M. Falkenmark if renewable freshwater availability falls below 1000 M3 per capita, water supply begins to hamper health, economy growth and human well being.

  5. Why Project is required ?

  6. Gujarat is a water scarce state, with 6.39% of geographical area, 5% of population & only 2% of water resources. 71% of water resources available in 25% of geographical area of central & south Gujarat. In Saurashtra region per capita water availability is only 540 M3/annum against 1700 m3/annumminimum requirement. In Saurashtra region,only 15 lakh ha agricultural land will cover under irrigation (including Sardar Sarovar Project), against 42 lakh ha agricultural land. Hence, 27 lakh ha agricultural land will remain rainfed.

  7. The excessive pumping of groundwater resulted in intrusion of saline water up to 10 km of entire coastal belt of Saurashtra. The water storage capacity of Gujarat state is 20480 Mm3 in 196 medium & major reservoirs, against the total rainwater availability of 38000 MCM per annum. Non availability of any suitable site for major irrigation scheme in the state, the “Gulf of Khambhat Development Project” is the only option available to store 10,000 MCM rainwater.

  8. GULF OF KHAMBHAT DEVELOPMENT PROJECT (W.R.)

  9. Salient features (Tentative)

  10. Estimated Cost of the Project • Earlier the dam was envisaged between Ghogha to Hansot having length of 64 km. wherein tidal power component was combined alongwith development of fresh water reservoir in the Gulf. • As per pre-feasibility report of the project, the cost of project was estimated of Rs. 53,000 crore (base year 1998) in which the tidal power component was Rs.33000 crore. Considering, average 8% inflation per annum present cost works out to approximate Rs.1,40,000 crore, in which the tidal power component is Rs.86,000 crore.

  11. Recently, tidal power component is delinked from the project and the dam alignment is shifted northward by 15 km, leads to reduction of length of dam from 64 km to 30 km & height of dam is also reduced from 55 m to 35 m. • Considering above the approximate project cost at present is Rs. 50,000 to 60,000 crore.

  12. Benefits of the Project

  13. GULF OF KHAMBHAT DEVELOPMENT PROJECT (W.R.) Irrigation Benefit

  14. Irrigation Benefit 10.54 lakh ha. land in 39 talukas of 6 districts of Saurashtra region will get irrigation facilities including rejuvenation of rivers and filling of more than 60 existing dams as well as check dams, tidal regulators, spreading channels permanently.

  15. PerceivedAgricultural Benefits

  16. Transportation Benefits

  17. Transportation Benefit • Substantial saving in travel time and fuel due to reduction in distance by about 200 km between Bhavnagar and Surat. • Surat is one of the fastest growing city in the country and the diamond oriented business hub of the world. • Most of the diamond workers (more than 10 lakhs) are migrated from Saurashtra (Mostly, from Bhavanagr, Amreli district).

  18. After the completion of dam and Bhadbhut Barrage, the route from Bhavnagar to Surat will be Bhavnagar—Dahej—Hansot—Olpad—Surat. • New coastal highway will be developed to connect present petro-chemical hub Hazira (Surat) to future petro-chemical hub PCPIR (Dahej). • 10 lane road is proposed on the top of the dam. 75000 vehicles per day is estimated for year 2020, and 1,00,000 vehicles per day for year 2030.

  19. The toll-tax generation is estimated approximately Rs. 1500 crore for year 2020 and Rs. 2000 crore for year 2030. • Considering 10% I.R.R., Capital investment of Rs.15,000 crore to Rs. 20,000 crore may likely available from transport component (30% to 40% cost of the project)

  20. Land Reclamation Benefits • Gulf of Khambhat is one of the Gulf in world having maximum tide of 11 m and the average tide of 8.8 m . • During the high tide and flood in Narmada, Mahi, Sabarmati river etc., the sea water rise up to level of +7.0 m to +8.0 m from MSL. • After closure of the Gulf of Khambhat, land which is frequently submerged during high tide will be permanently opened. • About 1.5 to 2 lakh ha land along the periphery of reservoir will be opened which can be used for the project development.

  21. Land recovery (As per BISAG Study)

  22. Value Addition Of Land • Projects in vicinity of Kalpasar project • Dholera SIR • Fedara International Airport • PCPIR at Dahej • SEZ, GIDC etc. • Delhi- Mumbai Industrial Corridor

  23. Proposed 10 lane road for Ahmedabad-Bhavnagar route • 2000 sq. km world’s biggest fresh water reservoir (in sea) with 6-lane periphery road of 270 km long • Solar and Wind power, Tourism, Bio-fuel park, Transportation, Fisheries etc. project components / benefits

  24. Benefit -Reduction in Salinity In coastal region of Saurashtra and Central Gujarat, saline ground water will be converted into sweet water, resulting reduction in inland salinity

  25. Benefit- Port Development on d/s of Dam Project presents highly attractive locational attributes for port development downstream of the dam such as increased water level, lower current velocity, reduced sedimentation

  26. NIO MODEL STUDY • Model study results show that after the construction of the dam the tide level increases at all the port locations. • The currents decrease at the locations near to the dam (Bhavnagar, Ghoga). • Sediment transport results indicate that the sediment concentration reduces in the southern gulf (outside the dam) with a maximum reduction at Dahej and Gogha. • Bhavnagar port will be rejuvenated, therefore this region will be speedily developed

  27. Benefits- Generation of Non-conventional Energy Wind and solar power would be generated which will also be used for lifting of fresh water of reservoir.

  28. Wind Energy Wind energy is planned to be used for pumping of irrigation water. Approximately 250 crore unit will be required for lifting irrigation water. As per Suzlon study, 1600 MW with an estimated cost of about Rs. 9000 crore can be generated by installing wind mills/ solar units. Wind mill will have added benefit of its installation after dam construction.

  29. Benefits-fisheries Development • Fish production to the tune of 3,00,000 tonnes per annum amounting to Rs.22,500 Million at full development stage • Direct employment to approximately 1,00,000 beneficiaries and indirect employment to approximately 3,00,000 beneficiaries.
