The basic amenity for a highly civilized community needs water and drainage facilities; with uncontrolled population outrage, there arises demand for water consumption which naturally leads to effluent discharge. Even though the district has ample landscape, smart drainage facilities, the rainwater and storm runoff are still collected as pumped source for treatment to a long distance. These wastewaters diverted to the river surface due to insufficient retention time for treatment that naturally grounds a serious ecological damage. The concentration of organic and inorganic heavy metals determines the nature of contamination whether lighter low concentrated or severe high concentrated, meanwhile the level get diluted with streaming in the river surface. Deposited contaminants along the Porunai river basin are in dissolved stages that naturally lead to eutrophication which will cause pollution risk and indirectly affects the dependents covering three districts. With the support of GIS, online monitoring is incorporated to check the gathering of phosphorus, removal of phosphorus from the soil and nitrogen removal. The aim of the research focus is to study eutrophic nutrient limits in river Porunai which is a streaming of Thamirabarani and manimuthar. Nutrient removals from the designed reactors express the available measure of pollution risk. Life cycle study gives the life term of river front and a blueprint is framed based on reducing the mixing of unwanted water sources. In due course make it a place of recreation prevailing with current scenario and future prediction by means of statistical data compared with navigation studies.
