Clair Water Fall. Could we say the same thing about the feasibility of the Upper Kotmale Hydropower Project? Water is to be harnessed from seven tributaries, Devon oya, St. The diversions would be above the waterfalls. The waterfalls will dry up, for which the CEB has offered to release a little water from time to time! The water is to be collected into a "pond" built at Talawakele, and from there taken by a 13 Km. Since then there has been many protests, which have been able to delay its commencement.
Design uncertainties such as lack of flash flood area. Lack of proper plan for the relocation of about families. Kothmale in the Evening.
This credit has to be paid back by our children and their children, who would never have the opportunity to see these wonderful waterfalls and the breathtaking beauty of the region, and they would be paying for a Hydropower project which probably would not be generating any electricity at the rate we are destroying our forest cover.
As is usual with most foreign credit, Japan would be funding a Project which they would never have approved in their own country, where they hold waterfalls as sacred places and they value their environment more than most other people.
But they would not mind destroying waterfalls in another country. The other contradiction is that JBIC also funds afforestation and sustainable environmental management projects in other countries, perhaps they want to grant another loan some day to Sri Lanka to rebuild the environment they are going to destroy through the UKHP.
We should try to negotiate with JBIC to get this funding for the desilting and regaining the maximum generation capacity from the existing projects and for ways and means of power saving and reducing wastage.
There has been no attempt to try to learn from the mistakes made over the years. In addition to the heavy financial burden of repaying all the foreign loans raised for these projects, and the disaster caused to the environment and the forest cover, the human suffering caused by these projects cannot be valued.
People who were uprooted from their ancestral homes, where they were earning a reasonable livelihood and contributing to the national economy by their agriculture and animal husbandry, were re-located in arid, desolate, recently cleared jungle land, with a promise of heaven on earth.
But all they inherited was a waterless desert, without even the basic facilities of health care transport education or other social services.
The author walking through the dried up Kothamale resovior.
The promised prosperity from increased agriculture has not yet materialized. The production is decreasing, because every year the amount of water stored in the reservoirs keep diminishing.
The people in power bragged that Sri Lanka would be exporting electricity to India after the Mahaweli Project is completed, yet a few years ago the people faced 9 hour power cuts, when it was blamed on dependence on Hydro power. The country was informed that the long term solutions to our power needs cannot be found in hydro power but in alternate thermal power. This was when they wanted to promote coal power. Over , people have already been displaced by the irrigation and hydro power projects in Sri Lanka.
Already 13 families were displaced from Kotmale when the Kotmale Project was done. Today, the Kotmale reservoir does not collect sufficient water to generate power even for six months a year.
Now the Upper Kotmale Project is to be considered, knowing very well that it would have the same fate. Over the last few decades over 50 million people around the world had been displaced due to construction of dams. They are the people who are more dependent on natural resources.
When such resources are degraded they suffer the most. The project initially faced several objections, before being officially permitted by courts of law.
Construction work on the project then began in , and is expected to be completed by the end of Construction and development[ edit ] This project is estimated to cost a total of up to Rs. Phase 2: All key civil engineering works, such as construction of tunnel, dam, underground power house etc.
Phase 3: Hydro-mechanical works such as construction of spillways, penstocks, intake gates, etc. Phase 4: Electro-mechanical works such as generation installations, construction of the switchyard, fire fighting system, communication system, etc. Phase 5: Construction of the A total of 2, construction workers are employed at the site, of which 2, are locals, and are foreign.
Dam and reservoir[ edit ] Preparations upstream for the creation of the Upper Kotmale Reservoir. The gravity dam measures Water from the reservoir will be used for both irrigation development and hydroelectric power generation.
Tunnel[ edit ] During the construction work of Headrace tunnel The 4. The tunnel begins at the dam site, and stretches north at a distance of approximately 7. Excavation on the tunnel was completed and ceremonially opened by President Mahinda Rajapaksa on 4 November It has installed electrical capacity of MW from two 75 MW turbines , capable of producing up to GWh of power annually. Water arrives at the powerhouse from the dam via the An outdoor switchyard measuring Transmission line[ edit ] The kV transmission line of the Upper Kotmale Hydro-power Project connects the power station located at Niyamgamdora, Kotmale, to the national grid via Kotmale switch yard located in Atabage, Gampola.
The line consists of 45 towers and has a length of The double circuit transmission line has a capacity of MW per circuit.
