The Sardar Sarovar Dam project includes:
1) A gravity dam on the Narmada River near Navagam, Gujarat that aims to provide irrigation, drinking water, and hydroelectric power to parts of Gujarat and other states.
2) A reservoir with storage capacity of 5,860 cubic hectometers that will irrigate over 1.8 million hectares of land and provide drinking water to over 29 million people.
3) Installed hydropower capacity of 1,450 megawatts to generate electricity.
2. GENERAL
INFO:
The Sardar Sarovar Dam is a gravity dam on the Narmada river
near Navagam, Gujarat in India.
It is the largest dam and part of the Narmada Valley Project, a
large Hydraulic engineering project involving the Construction of
a series of large irrigation and Hydroelectric multi-purpose dams
on the Narmada river.
3. Histor
y:
The plan for harnessing the river for irrigation and power
generation in the Narmada basin was initiated in 1946. Seven
projects including the Bharuch project were identified during
the initial Survey and 4 projects Bharuch (Gujarat), Bargi,
Tawa and Punasa in Madhya Pradesh were given top priority
for investigation. After the completion of investigation, the
proposed dam at Gora in Gujarat with the full reservoir level
(FRL) 161 ft (49.08m) was selected and the foundation stone
was laid by late Prime Minister, Pandit Jawaharlal Nehru on
5th April, 1961.
4. PURPOSE OF THE

capacity of 1200 MW and 250 MW respectively. The
power would be shared by three states - Madhya
Pradesh - 57%, Maharashtra - 27% and Gujarat 16%.
It will also provide flood protection to riverine reaches
measuring 30,000 ha. covering 210 villages and
Bharuch city and a population of 4.0 lac in Gujarat

8. WILD LIFE
Wild life sanctuaries viz. "Shoolpaneshewar wild life
sanctuary" on left Bank, Wild Ass Sanctuary in little Rann
of Kachchh, Black Buck National Park at Velavadar, Great
Indian Bustard Sanctuary in Kachchh, Nal Sarovar Bird
Sanctuary and Alia Bet at the mouth of River will be
benefited.
ADDITIONAL PRODUCTION
SSP would generate electricity. On completion, annual
additional agricultural production would be Rs. 1600
crores, power generation and water supply Rs. 175
crores, aggregating about Rs. 2175 crores every year
equivalent to about Rs. 6.0 crores a day.
9. The Narmada River & Basin:
The Narmada, the largest west flowing river of the Peninsula,
rises near Amarkantak range of mountains in Madhya Pradesh.
It is the fifth largest river in the country and the largest one in
Gujarat. It traverses Madhya Pradesh, Maharashtra and Gujarat
and meets the Gulf of Cambay.
The total basin area of the river is 97,410 square kilometer
comprising 85,858 square kilometer in Madhya Pradesh,
1658 square kilometer in Maharashtra and 9894 square
kilometer in Gujarat.

14. REVENUE:
Accoding to Lahiri, Chairman, Sardar Sarovar Narmada
Nigam: daily revenue of 7 crore at Rs. 2 per unit
6 major dams and 20 medium dams are either ready or
on the verge of completion.

Exact figures unknown but hydroelectricity will be major
revenue generation means of the project
15. Solar Power Generation:
In 2011, the government of Gujarat
announced plans to generate solar
power by placing solar panels over the
canal, making it beneficial for the
surrounding villages to get power and
also help to reduce the evaporation of
water. The first phase consists of
placing panels along a 25 km length of
canal, with capacity for up to 25 MW of
power.
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.
Histor
y:
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.
