Water, Environment: Tarrant Regional Water District Richland Chambers Wetlands
The Tarrant Regional Water District Richland Chambers Wetlands project, near Fort Worth, is now the second-largest constructed wetlands in the U.S. Completed in October 2013, the $43-million project exemplifies a trend in water treatment in which natural systems are used to assist in filtering and improving water quality.
In this case, water is diverted from the Trinity River, which is sometimes dominated by highly treated flows from a nearby wastewater treatment plant, into the Richland-Chambers Reservoir to provide additional raw-water supply. The 1,880-acre wetland system acts as a "living" filter that removes phosphorus, nitrogen and other nutrients.
