• Why this project?

Dams on rivers did not suffice water requirement due to poor monsoon

185 rivers in Gujarat & only 8 are perennial

Use ground water for irrigation & water supply purpose

Sources of water

Narmada project

Introduction : CONCEPT OF KALPASAR

What does ‘Kalpasar’ exactly mean ?

'Kalpasar' means a lake that fulfills all the wishes. The word originating from Hindu mythological 'Kalpa Vriksha' - wishing tree.

This grand scheme called Kalpasar is conceived and developed by utilizing the concepts of two most successfully implemented projects in the world.

Kalpasar project Dutch project

Narmada,mahi and sabarmati big rivers bring water

Tributary of rhine bring water

Distance between bhavnagar and bharuch reduce by 250 kms

Hurich of North Holland and Den Oever of Friseland come closer by 200 kms.

The estimated land reclamation is 2,00,000 hectares

165,000 hectares alredy reclaimed

The lake will be of 2900 sq kms The lake is of 3200 sq kms

Similarities between Kalpasar project and Dutch project:

Total length of dam 64,160 m including 23,500 m of inland dykes

BENEFITS OF KALPASAR PROJECT:1. Water supply for

domestic: Kalpasar freshwater

reservoir would provide 900 million m³ for domestic use.

2. Irrigation from freshwater reservoir:

About 10.54 lakh hectares of land is going to irrigate and about 1,19,000 hectares of saline land is also cultivate.

5. Land Reclamation:

119000 ha will be used for several purposes because of this project

3. Water supply for industrial use: 500 million meter cube is provided for in the freshwater lake of Kalpasar for industrial use in the water scarce areas

4. Tidal Power :

This project will produce 5,850 MW of pollution free power through a hydropower

Under the present conditions two ports are in use in the gulf of khambat area -The all weather direct berthing port of bhavnagar. -The fair weather lighter age port in Dahej.

9.Navigation Port Development:

8. Waterborne transport development: Inland navigation, along Narmada

river from sea to Hoshangabad (in Madhya Pradesh) through Kalpasar Lake

CHALLENGES FACED BY PROJECT: Financial status :

The total investment goes up to 54000 crore rupees which involves about 37000 crore rupees for the dam construction and other ancillary expenses

Technical complication:• Nature of rocks:

Nature of rocks surrounding the gulf coastline is quaternary in nature consisting of miliolites, alluvium soils and coastal deposits

• Structural disposition: Kalpasar project is situated on the intersection of the 400 km wide and 150 km long Cambay fault zone

• Nature of surface: Around the gulf is not only saline but it is extensively marshy in nature

KALPASAR 18

CONCLUSION :- From the above data and studies it is quite evident that

KALPASAR is “Big Beyond Limits” and involves a lot of ramification.

This project will make Gujarat a DREAMLAND. If this project implemented with dedication and without corruption then it will give a massive benefits.

Hence, this project is a innovative step towards the development of “New Gujarat” and should be taken for very specific and detailed considerations.
