Globally about 172.32 billion cubic meters of sewage water is released untreated yearly this becomes of economic constrains for construction and maintenance of sewage water treatment plants (STPs) ,even the treated water of STPs not reusable due to presence of heavy metals but with an indigenous technology the heavy metals reduced from sewage water for the evaluation of the water, Channa striata fish grown in STP treated water ,control osmania university campus pond water and sewage water with indigenous technology .where the heavy metals of STP treated water and even control water shown effects on weight, length and distributional characters of Channa striata. Heavy metals are stable and are determined as environmental contaminants since they cannot be degraded or destroyed; therefore they accumulate in the soils, water and sediments. Three water i.e., control water (osmania university pond), treated STP water were collected from Hyderabad area which were analyzed to investigate the concentration of heavy metals like Cr, Mn, Fe and Co etc... In the present study polluted sewage water was treated by using C.V. Technology from 2019 to 2022. The results indicated that concentrations of heavy metals were high in STP treated water and few are present in osmania university pond water compared to sewage water treated with CV technology, which were within the permissible levels.
