This article basically determines the assets in which water resources are polluted the environment by anthropogenic sources like agricultural and household formation.  As matter of fact Public think that the environmental impact of wastewater pollution has increased day by day many conventional wastewater treatment techniques like chemical adsorption  Hence the activated sludge are applied to remove the pollution but there are still some limitations which have high operation costs. The use of wastewater treatment in public and private works as a different medium is receiving increased interest so that its low operation and maintenance costs. As per as the water treatment is concerned it is easy to have a good effectiveness and ability for degrading contaminant. Hence, this paper reviews is the use of wastewater treatment technologies to remove contaminants from wastewater like a high oxidant which represent the main pollutants in wastewater as per as a financial modeling of the public private partnership of wastewater treatment.
