Abstract: Water Basin or tanks are very necessary attribute of either towns or rural environment. While urban lakes are present all over the world, in a country like India, the lakes in rural areas fulfill a variety of functions; drinking, irrigation, live-stock rearing and ground water recharge. In India, several water tanks recently have been astray, because of various manmade movements and the many of remain water tanks are degraded day by day. Many areas of water tanks in the world getting polluted by dumping and discharge of various kinds of effluents, wastes, etc., without any proper treatments., all these leads to degrading the quality of water and leads to changes in environmental conditions. For satisfactions of various water demands in local area, it is necessary to construct rainwater harvesting pits and to make channelizing of water to restore. So that, such water tanks serves many functions in a useful ways i.e. water may use for irrigation, to satisfy domestic demand and also may increase the ground water table and control of floods, etc. (Ganesan M 2008 et al, Mahapatra DM 2011 et al., Sudha M C 2013 et al.,). In this present study attempt has been made during Pre-Monsoon (April to May) and Post-Monsoon (September to October) periods to find the concentration levels of heavy metals, Arsenic (Ar), Copper (Cu), Cadmium (Cd), Chromium (Cr), Lead (Pb), Mercury (Hg), Zinc (Zn) and Boron (B). Sampling has been done by considering the inflow and the other outlet discharges, where the possibility of contaminations may enter into the water body by awning all over of the lake for taking samples, and also discussed the suitability of water for various demands and suggested required management techniques to make water free from the contamination.
