Sardar Sarovar Namda Dam today The historic surface


  Sardar Sarovar Namda Dam today The historic surface 

        Sardar sarovar dem Narmda dem

         Sardar sarovar Narmada den For this, the construction of the main dam near Nawagam near Kavadia in Narmada district of Gujarat state has been completed and the dam is still in operation, but its height is constantly increasing, for which construction is currently underway. The construction of the canals of the Sardar Sarovar project as well as the hydroelectric station is almost complete. The total height of the dam has been suggested to be 1.5 meters (about 3 feet), which was disputed due to the Narmada Bachao agitation and the Supreme Court of India has been allowing the height of the dam to be increased.

      Irrigation water reaches the inland villages of Gujarat, Saurashtra and Kutch districts through the canal branch and sub-branch canals. This closed RCC in the construction sector. (Cement concrete) is the second largest enclosure in dams. Apart from Gujarat, Rajasthan and Madhya Pradesh are also benefiting from the hydroelectricity currently produced in the dam.

     Planning for irrigation and hydropower production of the Narmada Valley was initiated in the evening. In the initial exploration, seven irrigation schemes including Bharuch Irrigation Scheme were decided and four projects like Bharuch (Gujarat), Bargi, Tawa and Punasa were given priority for exploration. Upon completion of the exploration, a 5-foot (1.5 meter) full reservoir surface (FRL) near Gora village in Gujarat was selected and the plan was laid. This was done on April 7, 9 in the hands of Pandit Jawaharlal Nehru. However, after receiving more detailed modern maps from the Survey of India, consideration was given to the possibility of increasing the height of the dam so that maximum water can be used.

      In order to resolve the dispute over the share of Narmada water between the governments of Gujarat and Madhya Pradesh, the Government of India issued the 3rd self. Dr. The chair of Khosla constituted a committee, which recommended the construction of a higher dam with a full reservoir surface (5 m) at the level of 7th. However, as per the report of Khosla Committee of the Madhya Pradesh Government, Narmada did not agree to the development of water and hence the Government of India constituted the Narmada Water Disputes Commission (NWDT) in October 3 under the River Water Disputes Act, 1. NWDT gave its final ruling on December 7.

         The obvious benefits of the dam's construction are as described in the Supreme Court ruling: Irrigation: 5,3 sq km of Gujarat The land, which is spread over 6 districts, 3 talukas and 3 villages (most of which is in the drought affected areas) and 2 sq km of Rajasthan's Badmer district and Jalor district districts. Will provide irrigation water to the deserted land.

        On February 7, the Supreme Court granted a green flag to increase the initial 5 meters height to 5 meters. On October 7, the Supreme Court again allowed the state government to lift the dam's height to 5 meters in a judgment with a majority of 1 to 5. On May 7, the Narmada Control Authority agreed to add another five meters to the height of the dam. On March 8, height was once more allowed, this time up to 5 meters. On March 7, the Narmada controlling authority allowed the height of the dam to be increased from 5.5 meters to 1.8 meters. On August 7, heavy rainfall shifted to the reservoir level of 5.5 meters (5 ft), which forced the occupation of the Narmada river to 1.2 grams. On June 7, the Narmada Control Authority gave final approval for the height of 1.8 meters (1.8 feet) to 1.8 meters (5.5 feet).

      The Sardar Sarovar Yojana has two power plants: (1) a 1 megawatt drainage underground hydroelectric station and (2) a mega watt canal hydroelectric station with a capacity of 2 mega watts. The benefit of hydropower is divided between Madhya Pradesh, Maharashtra and Gujarat in a ratio of 5: 1: 3, respectively. The power station has been constructed as an underground station on the right bank about 5 meters below the main dam. The power station has two Francis type reversible turbine generators with a capacity of 5 MW. The TG Setus was provided by Messrs Sumitomo Corporation, Japan and Messrs. BHEL. These units can be operated at a minimum reservoir surface of 1.5 meters. These six units have been launched in phases from February 1 to June 3. It depends on the water cover and the irrigation needs of Gujarat coming from the schemes for energy generation.

        The main canal front power station (CHPH) with an installed capacity of 3 MW (2 X 2 MW) is a surface type power station inside the saddle dam on the right bank of the reservoir. These five units have been launched in phases from August 1 to December 1. The unit can be operated at a minimum reservoir level of 1.5 meters. CHPH is administered in consultation with the NCA / WREB on the basis of irrigation requirements of Gujarat / Rajasthan and water discharged from Madhya Pradesh upstream schemes. The energy generated at these two power stations is fed through transformers of 6 kW (partially connected) to the GIS located in the switch yard at RBPH. These 2 kV switches are gas-insulated and indoor with a bus bar. This energy is delivered to the participating states ie Gujarat, Maharashtra and Madhya Pradesh at a ratio of 5: 1: 3 through 2 kV double circuit transmission lines ie SSP-Kasor, SSP-Assoj, SSP-Dhule and SSP-Nagda respectively. All transmission lines are operational and charged. The SSP power complex and transmission lines are being maintained and repaired by Gujarat State Electricity Company Limited (GSECL) for which O&M contracts have been signed between SasanNili and GSECL.

     Watershed above the Narmada Canal Slope (FALL) Edit Construction of small hydroelectric plants on the FALL of different canals of the Narmada project. Is in progress under the method. The energy generated from the above hydropower stations will be used to supply the energy of the pumping station under Sardar Sarovar. The information on the hydropower station on the canal slope (FALL) is as per the link given below.
