Constructed wetland is the biological wastewater treatment facility. These projects aim to treat wastewater and environmental sanitation problems through practical community based approaches. These problems confront the rapidly urbanizing cities in Asia. This is considered safe treatment and disposal method of wastewater. On the other hand conventional methods based on advanced technologies are simply not affordable or are complex to maintain in most medium and small sized towns. Constructed wetland is a complex assemblage of wastewater, substrate, and vegetation and an array of microorganisms. Vegetation has a vital role in the wetlands as it helps to serve in maintaining proper surfaces and a suitable environment for microbial growth of microorganisms and is a source of filtration. The collected samples indicate that physical, chemical and biological parameters are higher at the inlet as against NEQS. The same parameters show considerable reduction and acquire permissible levels at the outlet. From experimental results it was derived that reduction rate of analyzed parameters such as COD, BOD, TDS, salinity, DO, TSS, nitrogen, phosphorous, Fecal coli form was effective. From the experimental work, it was found that this system is effective in reduction of pollutants from wastewater excluding dissolved oxygen. The overall removal efficiency remained up to 65%. This system reduced BOD, COD, and TDS, salinity, TSS, nitrogen, phosphorous, oil grease and fecal coli form by 94.4%, 89.5%, and 45.36%, 16.6%, 97.55%, 49.77%, 57.38%, 51.43% and 97.2% respectively. It was concluded that this treated wastewater through constructed wetlands could be used for the agriculture and aquaculture purpose. Constructed wetlands are an effective option for on-site wastewater treatment when properly designed, installed, and maintained. Sub surface flow constructed wetlands are found to be a viable tertiary treatment alternative for municipal wastewater. These systems are potentially good, low-cost, appropriate technology treatment for domestic wastewater in rural areas where land is inexpensive.
