Walawe Ganga



The Walawe Ganga located in the south of Sri Lanka is the main source of potable water for the towns of Ambalantota, Hambantota and Hungama and the surrounding areas. Increased demand of drinking water and extremely low fresh water flow during the dry season, has caused salinity intrusion at the intake location. The high level of salinity intrusion has forced to relocate the intake further upstream. However, due to unaffordable transmission costs it is now realized that constructing a salinity barrier is the most feasible solution to this problem. The barrier is also necessary to abstract an additional quantity of 25,000 m3/day at Ambalantota for the Hambantota water supply augmentation program under the ADB funded project.
This 30m-high fall originates from a rainforest. To the east is Duli Falls and there is another to the west. Take the Balangoda - Kaltota road via Wekiliya and Watawala to Mulgama. The journey of 8km is best undertaken in a four-wheel drive vehicle. The Balangoda rest-house is 22km away.
