This study examined how treated wastewater discharge influences key physico-chemical water quality parameters in an urban river system. Using field sampling and statistical analysis, the research identified localized changes in parameters such as dissolved oxygen, electrical conductivity, and biochemical oxygen demand near the effluent discharge point.

The findings highlight an important environmental insight: even treated wastewater can cause localized impacts on river water quality, emphasizing the importance of site-specific monitoring and sustainable wastewater management.

This work also contributes to broader sustainability goals, particularly SDG 6 – Clean Water and Sanitation, by supporting improved water quality monitoring and environmental protection and some other SDGs.
