Anawilundawa is made up of nine tanks linked together to form a unique irrigation system. The six large tanks – Pinkattiya, Maradansola, Anawilundawa, Mayyawa, Surawila and Vellawali – and three smaller peripheral tanks, exist as a single system and are located close to Nalladarankattuwa. Although there is no longer a definite trace of the waterways that fed the system, the system is now watered by the flood waters of the Deduru Oya brought to the area via the Sengaloya scheme. The Anawilundawa tanks abound with birdlife and is one of the three RAMSAR wetlands in the country.
