Abhaya Wewa (Sinhalese: Sinhala; Sinhalese: අභය වැව), historically Abhayavapi (Sinhalese: Sinhala; Sinhalese: අභයවාපි) or Bassawakkulama reservoir, is a reservoir in Sri Lanka, built by King Pandukabhaya who ruled in Anuradhapura from 437 BC to 367 BC, after constructing the city.[1]
It was constructed in 380 BC. The dam of the reservoir is 10 m high. The water of the reservoir is also accumulated in the Giritale and Kantalai.[2] Currently, the reservoir is about 255 acres. The embankment of the reservoir is about 5910 feet long and 22 feet high above the sill level of the sluice.[3]
Area is 1235acres; the length of the Waw Kandiya (Sinhalese: Sinhala; Sinhalese: වැව් කන්ඩිය English: embankment) is 5910feet and height is 22feet. The width of the top of the embankment is 6feet to 8feet.[4] [5]
Built inside the ancient Anuradhapura, it supplied water to the city population.[4] [5]
King Paduwasdeva of Sri Lanka, when married Subaddhakacanna from North India, and her seven brothers also came to Sri Lanka and established their villages. One of the brothers, Anuradha established Anuradhapura where he constructed the first reservoir. The reservoir was expanded by king Pandukabhaya. The reservoir was called Abaya Vapi at that time, in memory of one of King's uncles. The reservoir was used to feed the irrigation system.[3] [6] [7]
