Disposal of treated sewage has been increasingly important in the development and planning of wastewater management. The objective of the study is to investigate the impact of artificial recharge of treated domestic sewage in an unconfined aquifer. Once the pollutant reaches the soil, there are several factors that affect the soil behaviour. Therefore, it is imperative to know the impact of disposal of treated sewage in different soils available locally in the coastal belt of the southwest coast of India. This study will help in easing the disposal in streams by adding up a new form of disposal in all-time weather conditions. The objectives of this study include treatment efficiency and its quality before and after the recharge in sand and soil as a dispersion media. The experimental model has shown enough potential in the removal of pollutant concentration in media dispersion. The percentage removal of dependent variables, such as biochemical oxygen demand and chemical oxygen demand is found to be 51.65% and 83.01%, respectively in the sand and also 83.34% and 50% in soil, respectively.
