The Kalu Ganga Dam is a large gravity dam, and the second vital component of the larger and more complex Moragahakanda — Kalu Ganga Project, currently under construction across the Kalu Ganga ("Black River") at Pallegama, in the Matale District of Sri Lanka. Construction of the project was launched by President Mahinda Rajapaksa on 25 January 2007.[1]
The larger combined project involves the construction of the Kalu Ganga Dam and Reservoir, along with the separate Moragahakanda Dam and Reservoir, for irrigation and power generation purposes. Both these sites would be located approximately 10 km (6.2 mi) apart.[2]
The total development cost for both sites totals to approximately Rs. 48.145 billion (approximately US$370 million) and is being carried out by SMEC Holdings and Sinohydro.[3][4][5]
Funding
The development of the Kalu Ganga segment would cost US$167 million. 22% or US$37 million of this is funded by the Kuwait Fund, 27.5% or US$46 million is funded by the Saudi Fund for Development, while the rest if borne by the Government of Sri Lanka. The funds will be payable in 20 years, including a 5-year grace period.[6]
The funding from OPEC will carry an interest rate of 3.2%, and a service charge of 1% on the principle amount withdrawn and outstanding.[6]
Dam and reservoir
The primary Kalu Ganga Dam will be a 67 m (220 ft) high concrete gravity dam, measuring 546 m (1,791 ft) in length. To support the new Kalu Ganga Reservoir created by the dam, two additional saddle dams will also be created to contain the reservoir. The primary dam and saddle dams are estimated to cost approximately US$102.2 million.[4][6]
In addition to using the reservoir's water for irrigation, a percentage of it would be consistently transferred via tunnel to the Moragahakanda Reservoir for further irrigation uses and hydroelectricity generation.[1]
