The use of constructed wetlands for wastewater treatment is becoming widespread all over the world due to the demand for water quality improvement for reuse; and also to compensate for the loss of natural wetlands. This booklet provides a valuable introduction to constructed wetlands and it will raise awareness of their value among environmental professionals.
The constructed wetland treatment system is a cheap and low-cost alternative for wastewater treatment. The use of constructed wetlands started in Malaysia in 1999 with the creation of the 650 ha Putrajaya Wetlands which is believed to be one of the largest constructed freshwater wetlands in the tropics.
Constructed wetlands are engineered wetlands that are built to emulate the functions of natural wetlands for human needs. The booklet demonstrates how this system promotes sustainable use of local resources while relying on renewable energy sources. Wetland plants and microbes are the active agents in the treatment processes.
The system can tolerate various pollutants and could be used by various users including governmental departments and agro-based industries in treating wastewater before it is discharged into natural waterways.
In addition to water purification, constructed wetlands also serve as a wildlife sanctuary and provide habitat for wildlife. The system can be aesthetically pleasing and serve as an attractive destination for tourists. Aside from that it can also be developed into a wetland education centre.
