The tank cascade system (Sinhala: එල්ලංගාව, romanized: ellaṅgāva) is an ancient irrigation system spanning the island of Sri Lanka. It is a network of thousands of small irrigation tanks (Sinhala: වැව, romanized: wewa) draining to large reservoirs that store rainwater and surface runoff for later use.
Sri Lanka’s tank cascades (a network of small tanks that store surface water) are one of the country’s greatest legacies from a remarkable hydraulic civilization, built by its ancient kings as a solution to the water scarcity in the country’s dry zone, over 2,000 years ago.
The Anton water tank can be used for a multitude of purposes including storage of drinking water, drip irrigation systems, agriculture, rainwater harvesting systems, fire suppression, agricultural farming and livestock, chemical manufacturing, food preparation, and more.
