In addition to constructing underground canals , the Sinhalese were the first to build completely artificial reservoirs to store water , referred to as tanks ...
Some districts of Sri Lanka have epidemic rates of Chronic Kidney Disease of Unknown Etiology (CKDu). [29] Pollution of groundwater by chemical-agricultural runoff is a suspected factor; men are more likely than women to develop the condition. [29] Kidney disease rates are highest in areas that use water diverted from the Mahaweli River. [32]

By the late 1960s the tank's bund was 4.5 mi (7 km) long and 10 ft 4 in (3 m) high whilst the tank's storage capacity was 26,600 acre⋅ft (32,810,617 m 3) and its water spread area was 4,550 acres (1,841 ha). [1] There was a 172 ft (52 m) channel flow spill on the right bank and seven sluices. [1]
Sri Lanka is pockmarked with many irrigation dams, with its water resource distributed across nearly the entirety of the island for agricultural purposes via artificial canals and streams. Utilization of hydro resources for agricultural production dates back to the pre-Colonial era , with the current crop production now largely dependent on ...
