Shri. Narendra Modi's Kalpsar project

  1. 1. PRESENTATION ONGULF OF KHAMBHAT DEVELOPMENT PROJECT(WR)Kalpasar as a prospective Water solution - Saurashtra A Truly Matchless Project
  2. 2. MISSION
  3. 3. VISIONTo create world’s largest fresh water reservoirin sea, by constructing 30 km long dam in theGulf of Khambhat, to store more than 10,000MCM of surface water, i.e. 25% of volume ofState’s average annual rain water inflow.
  4. 4. Per Capita Availability of Water Water 2001) Per Capita Availability of (Year 730 m3/Annum North 343 m3/Annum Kutch Gujarat PALANPUR RANN OF KUTCH MEHSANA LITTLE RANN Bhuj GANDHINAGAR AHMEDABAD Saurashtra KHEDA GODHRA SURENDRANAGAR540 m3/Annum JAMNAGAR VADODARA RAJKOT BHAVNAGAR AMRELI BHARUCH Central & JUNAGADH South SURAT Gujarat DANG 1880 m3/Annum 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. 5. Why Project is required ?
  6. 6. 1. Gujarat is a water scarce state, with 6.39% of geographical area, 5% of population & only 2% of water resources.2. 71% of water resources available in 25% of geographical area of central & south Gujarat.3. In Saurashtra region per capita water availability is only 540 M3/annum against 1700 m3/annum minimum requirement.4. 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. 7. 5. The excessive pumping of groundwater resulted in intrusion of saline water up to 10 km of entire coastal belt of Saurashtra.6. 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.7. 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.
  9. 9. Salient features (Tentative)1 Length of dam between two shores of Gulf Approx. 30 km2 Top of dam 100m wide 10 lane road + railway3 Reservoir features: (i) Full Reservoir Level(FRL) (+) 3.0m (ii) Maximum Water Level(MWL) (+) 4.0m (iii) Minimum Draw Down Level(MDDL) (-) 4.0m (iv) Live storage 10500 Mm3 (v) Storage between MWL & FRL 1900 Mm3 (vi) Reservoir area 2000 Sq.km4 Bhadbhut Barrage & Narmada Diversion Canal(i) Barrage including earthen dykes 10 to 12 km(ii) Narmada Diversion Canal Discharge 100000 cusecs Length 32 km
  10. 10. 5 Irrigation Command(i) Water envisaged for irrigation 6558 Mm3(ii) Envisaged three garland canal Discharge 4000 to 6000 cusecs Length 600 to 700 km Elevation EL50 m, EL80 m, EL100 m6 Life of reservoir 400 to 500 years7 Ground Water Quality 7,00000 Ha Improvement in Catchment area8 Land recover between 150000 to 200000 ha EL + 5.0m to EL+ 8.0m
  11. 11. 9 Reduction in distance Bhavnagar – Dahej 200 km Bhavnagar – South Gujarat 225 km10 Ports Bhavnagar port will be rejuvenate, Dahej port will be outside of reservoir, New ports are proposed at down stream of dam.11 Rivers debouching in the Sabarmati, Mahi, Dhadhar, reservoir Narmada (through diversion canal), Limbadi Bhogavo, Sukhbhadar, Utavali, Keri, and Vagad12 Construction of dam 5 to 7 years
  12. 12. 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.
  13. 13. • 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.
  14. 14. Benefits of the Project
  15. 15. GULF OF KHAMBHAT DEVELOPMENT PROJECT (W.R.) Irrigation Benefit
  16. 16. Irrigation Benefit10.54 lakh ha. land in 39 talukas of 6districts of Saurashtra region will getirrigation facilities including rejuvenationof rivers and filling of more than 60existing dams as well as check dams,tidal regulators, spreading channelspermanently.
  17. 17. Perceived Agricultural Benefits
  18. 18. Transportation Benefits
  19. 19. 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).
  20. 20. • 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.
  21. 21. • 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)
  22. 22. 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.
  23. 23. Land recovery (As per BISAG Study)
  24. 24. Value Addition Of LandProjects in vicinity of Kalpasar project• Dholera SIR• Fedara International Airport• PCPIR at Dahej• SEZ, GIDC etc.• Delhi- Mumbai Industrial Corridor
  25. 25. • 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
  26. 26. Benefit -Reduction in SalinityIn coastal region of Saurashtra andCentral Gujarat, saline ground waterwill be converted into sweet water,resulting reduction in inland salinity
  27. 27. Benefit- Port Development on d/s of DamProject presents highly attractive locationalattributes for port development downstream ofthe dam such as increased water level, lowercurrent velocity, reduced sedimentation
  28. 28. NIO MODEL STUDY i. Model study results show that after the construction of the dam the tide level increases at all the port locations. i. The currents decrease at the locations near to the dam (Bhavnagar, Ghoga). i. 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, thereforethis region will be speedily developed
  29. 29. Benefits- Generation of Non-conventional EnergyWind and solar power would begenerated which will also be used forlifting of fresh water of reservoir.
  30. 30. Wind EnergyWind energy is planned to be used forpumping of irrigation water. Approximately250 crore unit will be required for liftingirrigation water. As per Suzlon study, 1600MW with an estimated cost of about Rs. 9000crore can be generated by installing windmills/ solar units. Wind mill will have addedbenefit of its installation after damconstruction.
  31. 31. 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.
