The continuous clackety droning of drilling machines and excavators punctures the idyllic surrounds of the Temghar dam, some 50 km west of Pune. Started in 2010, the dam, with a capacity of 3,000 million cubic feet, was a key supplement to the ever-thirsty and fast-growing Pune city and region.
The Rs 314 crore reservoir is empty. It has been drained to facilitate a Rs 100 crore repair for a dam that leaks 10-12% of its contents due to poor construction.
The leaky Temghar dam has been problematic since its opening, with leaks springing up rapidly and the state being forced to blacklist its contractors and rush patches.
Let’s take a look at the other dams that are facing trouble:
- Tehri Dam
Scope: 2,400 MW hydropower generation in total, with a potential to irrigate 2.7 lakh hectares.
Problem: Concerns over the location in a seismically sensitive zone; questions over the displacement of people.
- Sardar Sarovar Dam
Scope: With a total capacity of 9.5 km, it is capable of generating a total of 1,450 MW of power.
Problem: There are still protests by people who have been displaced, demanding rehabilitation and compensation.
- Daudhan Dam
Where: Madhya Pradesh
Scope: The Rs 7,600 cr project aims to irrigate 6.35 lakh ha of arid land by transferring water from the Ken to Betwa river basins.
Problem: Ecological concerns; human displacement.
- Lower Subansiri Dam
Where: Assam-Arunachal Pradesh border
Scope: 2,000 MW hydroelectricity
Problem: Issues over flooding created by the dam, with concerns over its construction as well.
- Pancheshwar Dam
Scope: 5,600 MW multipurpose units, with total water storage of 12.26 billion cubic meters.
Problem: Issues over the displacement of people throughout construction; the place is ecologically sensitive.
- Polavaram Dam
Where: Andhra Pradesh
Scope: Irrigation capacity of 194 tmc ft and hydropower generation of 960 MW.
Problem: Changes in location due to technical and financial viability; tussle between states since this is part of a river-linking project; concerns over the large displacement of people.
