The constructed wetlands provide an exceptionally efficient cycle in the
process of cleaning wastewater. In wetlands, natural, physical, chemical and
biological mechanisms work together to remove and transform pollutants into
harmless by-products. Nutrients and toxic compounds are physically removed or
transformed by bacteria residing on the bottom of the ponds and on plant
surfaces. Aquatic plants produce oxygen, which helps kill bacteria and
Not only do wetlands purify water, they also provide a suitable habitat for
waterfowl, mammals, amphibians and insects. This type of ecosystem is one of the
most productive, natural purification processes on the planet.
Through the efforts of a dedicated group of scientists, researchers,
government officials and private citizens, the Tres Rios Constructed Wetlands
Demonstration Project is proving wetlands can effectively improve water quality
and provide wildlife habitat.
Currently the Tres Rios Wetlands is open to members of the public on a
special request basis. The portion of the wetlands in-river environmental restoration area,
from 105th Avenue to El Mirage Road, on Arizona Game and Fish land, has been
re-opened for access by the public for passive recreation. To make a special
request for access to the constructed wetlands, please send us an email and we mail you a access permit.
There are numerous books and websites that discuss the topic of wetlands. To
