Wetlands, which can be artificial or natural, which provide a low-cost method of wastewater treatment in both rural and urban regions. The term "Constructed Wetland Treatment System" refers to a system that is specifically designed to improve water quality as a major goal and is termed as CWTS. Many of these systems were built in the past to treat small quantities of wastewater contaminated with easily degradable organic debris from outlying sections of cities and towns. However, the desire for better water quality has increased in recent years, and water reclamation and reuse is now the primary driving force for the implementation of CWTS around the world. Natural wetland losses have prompted the establishment of constructed or manmade wetlands, also known as engineered wetlands, which offer the same roles and values as natural wetlands around the world. Planting emergent macrophytes, which go through the physical, chemical, and biological processes of natural wetland systems, gives CWTS its natural qualities. In the last 50 years, the number of CWTS in use has skyrocketed. Constructed wetlands are becoming increasingly popular and important. These systems are typically utilized in towns and cities for tertiary wastewater treatment. Surface-flow systems are typically used to remove suspended particulates as well as low concentrations of nutrients such as nitrogen and phosphorus. These developed wetland treatment systems are also employed to provide village residents with secondary sewage treatment. These engineered wetland systems have proven to be a cost-effective and energy-efficient approach to achieve high wastewater treatment efficiency. Wetlands are typically built for one of four basic purposes: to create habitat to compensate for natural wetlands that have been converted for agricultural and urban development, to improve water quality, to manage flooding, and to produce food and fiber (constructed aquaculture wetlands). In this study, sewage wastewater is treated by constructing a horizontal sub-surface flow created wetland with reed grass as vegetation to treat waste and clean sewage wastewater.
