Our ancestors, having known the greatness & importance of rain water, have created many water bodies for various uses. In ancient Tamil Nadu water bodies used for storage of rain water 1 were classified as Eri, Thangal, Kanmai, Oorani, Kulam, Enthal, Tharuvai, etc., Each name of the water body indicates a particular purpose of the water body. Eri (ஏ쎿) means Lake which is used for Irrigation Purpose. Thangal & Kanmai are the equal words of Lake in Thondai Mandalam & Pandi Mandalam respectively. Oorani means a water body that fulfills the drinking water needs of the Village. Kulam (埁ளம்) is the water body used for bathing. Tharuvai is the lake which has great water spread like a flat saucer that acts as its own catchment. Upon seeing this classification of water bodies based on their applications, it is wonderful to know the scientific approach of our ancient Tamil Nadu. Hon’ble Chief Minister of Tamil Nadu, having emphasis on conserving the water which is the lifeline to all living beings on earth, have formed an independent Department for effective management of the Water Resources in Tamil 2 Nadu vide G.O. (Ms) No. 55, Personnel and Administrative Reforms (A) Department, Dated 07.06.2021. Water Resources Department is more focused on meeting the water demands of the various sectors viz Agriculture, Domestic, Industries etc., by maintaining the water bodies and their infrastructure in a healthy manner. The Water Resources Department is taking up construction and maintenance of the dams, anicuts, check dams, canals, channels, tanks, ponds and inter linking of Rivers within the State apart from providing appropriate ground water recharge structures.
