The irrigation works in ancient Sri Lanka , the earliest dating from about 300 BCE, in the reign of King Pandukabhaya and under continuous development for the next thousand years, were some of the most complex irrigation systems of the ancient world. In addition to constructing underground canals, the srilanka were among the first to build completely artificial reservoirs to store water. The system was extensively restored and further extended during the reign of King Parākramabāhu (1153–1186 CE).

After King Pandukabhaya, King Parakramabahu I had many tanks built, with one large tank called Parakrama samudraya still providing water for agriculture.
