Irrigation minister Nimal Siripala de Silva said most of the large dams in the country except for some built in the last three decades were made out of packed earth and they had a life of around 50 years.
Most of Sri Lanka’s reservoirs called ‘tanks’ date from a 2,000 year old irrigation based civilization.
“Some have leaks, cracks, parts of the bunds have sunk, and spill gates and other safety mechanics had to be re-habilitated,” he said.
As part of the project some dams were lined with granite rocks to stop wave action from washing the dams away. With almost all reservoirs now at spill level erosion from wave acti
