irrigation schemes of
Sri Lanka, as evident from the earliest written records in the
Mahawansa, date back to the fourth century BCE (
Parker, 1881; Brohier, 1934). The purpose and determination in the construction of the irrigation systems are depicted by the words of
Parakrama Bahu I, 1153–1186 CE:
"Let not even a drop of rain water go to the sea without benefiting man". The Sri Lankan chronicle, the
Culavamsa which was written in the Buddhist
canonical language Pali, enumerates his works both as a provincial ruler in western Sri Lanka and later as the monarch of the whole country: he either built or restored 163 major tanks (reservoirs), 2,617 minor tanks, 3,910 irrigation channels, 328 stone sluices and 168 sluice blocks, besides repairing 1,969 breaches in embankments. Among the reservoirs he built was the tank at
Polonnaruwa, called on account of its size the
Parakrama Samudra (translation: Sea of Parakrama). With an area of and an enclosing embankment long, it irrigated nearly . The final achievements were highlighted by Sir
Henry Ward,
