The sewage waters are used as potential source of irrigation for raising vegetables and fodder crops around the sewage disposal sites. Soil contamination by sewage and industrial effluents has affected adversely both soil health and crop productivity. A study was conducted to evaluate the pollutant removal efficiency of lab scale hybrid constructed wetland system (HCWS) for recycling the sewage water for agriculture. Native aquatic plants viz., Brachiaria humidicola and Typha angustifolia were selected and utilized for the lab scale study. The results of this HCWS showed that removal efficiencies of BOD, COD was higher with the hydraulic retention time (HRT) of 5 days due to the combined effect of HF and VF by using the native aquatic plants like Brachiaria humidicola and Typha angustifolia.
