Waste water treatment plants are considered simple solutions for poor surface water quality and are used in every developed and developing society. There are varying types of waste treatment plants. The systems are rarely able to purify all water that passes through the system. The problem with a mix-and-treat waste water system is the strain from sudden influxes of water. Systems that combine storm runoff accept variability in the volume of water that needs treating. Effluent is discharged when the plant cannot treat all the waste. The purpose of this review is to determine which system is the closest to meeting the theoretical goal by analyzing the long-term effects of how effluent, verses unfiltered storm runoff, affect the quality of surface water. The results of this review will provide a direction for future research in determining a water treatment system with the least impact on the environment.
