The tank was built by damming the Diyawanna Oya with a 485-meter embankment.[3] It does not make use of the structure called Bisokotuwa, which helps to regulate water pressure at the sluice gates from inside the tank and protect the embankment from erosion. Instead that the sluice gate (Sorowwa) of the tank has been placed strategically away from the embankment and made up utilizing the massive natural rock around the tank.[4] It is said that this is the only such type sluice gate found in Sri Lanka.[5]
