There are a number of benefits of artificial wetlands over traditional treatment facilities. As far as the treatment side the systems are simple and so they are generally less expensive to build and operate, maintenance is easier, wetlands can tolerate different levels of water flow, and obviously they produce clean, but non-potable, water.
Oftentimes, when artificial wetlands are constructed the natural landscape is altered, and the location of the artificial wetland is not always ideal because of habitat fragmentation and other impacts of development such as direct mortality due to collisions with vehicles as result of road development.
