Abstract	Conventional soil-aquifer treatment (SAT) systems comprise of natural lithological sections up to the depth of zone of saturation or dried aquifers, which through geopurification process recharge the aquifers using domestic or industrial wastewaters. Such SAT systems have low infiltration capacity and frequently face the clogging problems, which causes environment hazards in the local areas. Under this study, three artificial set of lithologies (Lithology I, Lithology II, and Lithology III) were generated without using soil. Each one meter set of lithology was generated within a transparent cylindrical pipe of diameter 15 cm. Each lithology was equipped with nonwoven geotextile and geogrid material at different levels and comprises of coarse aggregate, fine aggregate, coarse sand, medium sand, and fine sand. Use of geotextile material within the artificial lithology shows approximately 8–10 times enhancement in the filtration capacity of the tested lithologies. Municipal wastewater (after primary treatment) was used to test the Lithologies I, II, and III. Between 100–200 l of wastewater was passed through each set of lithology everyday for seven days. Different water quality parameters such as pH, turbidity, electrical conductivity, fluoride, total suspended solids, biological oxygen demand, dissolve oxygen and carbon oxygen demand, chloride, and manganese were analyzed before and after passing through the lithologies everyday. One meter set of artificial lithologies have successfully reduced the concentration of measured water quality parameters between 60 and 93 %, without clogging. Lithology III equipped with superficial fine sand layer and two set of nonwoven geotextile has successfully removed 70–93 % concentration of wastewater. This study aims to demonstrate that a SAT system equipped with geotextile and without soil is more effective then the prevailing SAT systems. Study also proposed designs of SAT systems, which can be formed at unfavorable sites using abundant dry wells in which artificial set of lithologies can be used.
