Abstract:
The Malwathu Oya (called Aruvi Aru in the lower reaches), the second largest river basin in Sri Lanka, is flowing through the Anuradhapura city which is its ancient capital. This paper describes the cost benefit analysis of this project. The total project cost is Rs. 12,500 million, which consists of irrigation infrastructure development cost of Rs. 11,000 million and the other infrastructure development cost of Rs. 1,500 million. The main benefit of the project is the cropping intensity of the combined command areas of the two reservoirs Giant’s Tank and Akitamuruppu Tank, a total of 30,680 acres of lands, will be increased from around 1.0 to 1.7. In addition, the project entails a number of benefits which include generation of 4.0 gWh hydropower and provision of 2 MCM of raw water for drinking purposes. (2646, 93, 559)
