An initial 250-acre wetland created in 2007 wasn/wp-json/wp/v2/article/115670/u2019t enough to accommodate the region/wp-json/wp/v2/article/115670/u2019s population growth and the resulting influx of wastewater that is now roughly double the existing plant/wp-json/wp/v2/article/115670/u2019s treatment capacity. That wetland, Carrera says, has already become an oasis for migratory and resident birds like the endangered Yuma clapper rail, mammals like bobcats and foxes, and reptiles like chameleons. /wp-json/wp/v2/article/115670/u201cSo it is now a wildlife refuge,/wp-json/wp/v2/article/115670/u201d he says./wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n
In parallel with upgrades to the plant/wp-json/wp/v2/article/115670/u2019s treatment process, tentatively slated for 2025, a new series of intermediate water-filtering wetland basins will significantly improve the quality of the 3.5 billion gallons of reclaimed water before it flows into the larger wetland and then into the Colorado River Delta. Improving that flow can lower the concentration of other contaminants/wp-json/wp/v2/article/115670/u2014essentially using treated wastewater to help dilute pollution/wp-json/wp/v2/article/115670/u2014while nourishing the downstream estuary/wp-json/wp/v2/article/115670/u2019s wildlife./wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n
Carrera has alleviated some community concerns that the natural water purification won/wp-json/wp/v2/article/115670/u2019t be enough to clean the Colorado by emphasizing that the process will combine the filtering abilities of a more efficient treatment plant and the series of constructed wetlands to aid the ailing delta. /wp-json/wp/v2/article/115670/u201cThey are very conscious that the water, for them, means income,/wp-json/wp/v2/article/115670/u201d he says of local residents who depend upon the river for agriculture, fishing, boating, and tourism./wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/n/wp-json/wp/v2/article/115670/nFor many ecosystems, recycled water means life.
