1 PRESENTATION ON GULF OF KHAMBHAT DEVELOPMENT PROJECT(WR) A Truly Matchless Project

2 Geographical Location of Project

3 MISSION

4 VISION & PLANNING To create worlds largest fresh water reservoir in sea to store states 25% average annual surface water resources by constructing 30 km long dam across the Gulf of Khambhat. This reservoir will store MCM of surface water.

5 Surface Water Availability in State Population –year 2011 (India 1230 million) Geographical Area (India sq.km) Gujarat State 6.39% ( sq.km) Surface Water Availability (India -18,69,000 MCM) Gujarat State 5.0% (60.3 million) Gujarat State 2.0% (38,000 MCM) 5

10 Need of the Project

11 1.Gujarat is a water scarce state, with 6.39% of geographical area, 5% of population & only 2% of water resources of India. 2.71% of water resources of Gujarat is available in 25% of geographical area of central & south Gujarat. 3.In Saurashtra region, per capita water availability is only 540 M 3 /annum against 1700 m 3 /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.

12 5.The excessive pumping of groundwater resulted in intrusion of saline water up to 10 km of entire coastal belt of Saurashtra. 6.The rain water storage capacity of Gujarat state is Mm 3 in 196 major & medium reservoirs, against the total rainwater availability of MCM per annum. 7.Due to 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.

(iii) Envisaged three garland canals : Total pumping stations 11 LevelDischarge (cusec) Length (km) 100m m m Life of Reservoir400 to 500 years 7.Ground water improvement in periphery of reservoir 7.0 lakh ha

20 8.Extra land to be recovered1.5 lakh ha to 2 lakh ha 9.Reduction in distance Bhavnagar – South Gujarat 136 km 10. Ports: Bhavnagar port (will be revived), Dahej port (to remain out of reservoir), New ports are proposed at downstream of reservoir. 11. Rivers debouching in the reservoir : Sabarmati, Mahi, Dhadhar, Narmada (through diversion canal), Limbadi Bhogavo, Sukhbhadar, Utavali, Keri, Vagad, Kalubhar, Rangholi, Ghelo & Maleshree 12.Construction period for dam 5 to 7 years

21 Benefits of the Project

22 Irrigation Benefit

23 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. Irrigation Benefit

24 PerceivedAgricultural Benefits Perceived Agricultural Benefits

25 Transportation Benefits

26 Existing Route New Route Dam Alignment Detail of Road Route

27 Substantial saving in travel time and fuel due to reduction in distance by about 136 km between Bhavnagar and Surat/ Mumbai. 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). Transportation Benefit

28 After the completion of dam and Bhadbhut Barrage, the route from Bhavnagar to Surat will be BhavnagarDahejHansotOlpadSurat. 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. 70,118 vehicles per day is estimated for year 2025, and 2,07,529 vehicles per day for year The toll-tax generation is estimated approximately Rs crore for year 2025 and Rs crore for year 2055.

29 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. As per present planning, the fresh water reservoir have Full reservoir level at +3.0 m and maximum water level (during flood) is +5.0 m. Land Reclamation Benefits

30 Hence, the land which is frequently submerged during high tide between permanently opened above EL +5.0 m after closure of the Gulf of Khambhat About 2 lakh ha land along the periphery of reservoir will be opened which can be used for the project development. Land Reclamation Benefits

31 Levels in mArea in ha Between 5m to 6m54236 Between 6m to 7m Between 7m to 8m77749 Total Land Reclamation Benefits

32 Land recovery (As per BISAG Study)

33 Value Addition Of Land (1) Pipeline Important Projects Vicinity Dholera SIR Fedara International Airport PCPIR at Dahej Delhi- Mumbai Industrial Corridor (2)Proposed 10 lane road for Ahmedabad-Bhavnagar route

34 3)2000 sq. km worlds biggest fresh water reservoir (in sea) with 6-lane periphery road of 270 km long 4)Solar and Wind power, Tourism, Bio-fuel park, Transportation, Fisheries etc. project components / benefits

35 Due to sea water ingress in rivers upto 60 to 70 km, total peripheral ground water in 7,00,000 ha of Bhavnagar, Ahmedabad, Kheda, Anand, Vadodara and Bharuch district has became saline. After post dam scenario, due to only fresh water in rivers / catchment, this saline ground water quality with improve some time. Ground Water Quality Improvement

36 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

39 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, therefore this region will be speedily developed

40 Wind and Solar Energy As per Suzlon Companys observations for more than one year of two wind mast, the wind velocity more than 6 m/sec & density 200 watt / sq.m is available in periphery of fresh water reservoir. Suzlon has proposed three wind farm clusters of 2.1 MW, 700 wind turbines generators (1470 MW), which will generate 250 crore unit of electricity which will be sufficient for lifting 10,000 Mm 3 water from reservoir.

41 Wind and Solar Energy Total 4500 ha land will be required for erection of 1470 MW wind towers against that 2 lac ha land will be recovered. Wind farms will be installed after completion of dam on Public Private Partnership & the same land will be used for 800MW to 1000 MW solar panels. Hybrid model has been envisaged to get electricity for 8 to 9 months in a year.
