Highly contaminated municipal wastewater is being disposed of into land and rivers without anyprior treatment has severe side effects on human and marine animals. This research focused on thetreatmentof Majeed Keerio village municipal wastewater through horizontal flow constructedwetland system. The experimental study was evaluated and monitored timely over a year. Theoverall treatment efficiency performance of thewetlandsystem was determined by consideringorganic pollutants removal efficiency. This study emphasized on the design of horizontal flowconstructed wetland for the effective treatmentof municipal wastewater of village Majeed Keerio,Sakrand,Sindh. The constructed wetland efficiently reduced COD, BOD5,TSS, turbidity, totalphosphate, total nitrogen pollutants of wastewater, which was about 92.3%, 93%, 96%, 96.4% and74%,respectively. This method reduced all thermotolerant coliforms. Constructed wetland systemwas found most economical and effective for the treatment of domestic wastewater. The effect ofdifferent hydraulic loading rates under varying hydraulic retention times within the constructedwetland was examined. The higher hydraulic retention times resulted in improved pollutantsremoval efficiency
