Dry The region in the south of Mexicale, where the pale desert dominates the natural scene, the Las Arenitus wetland seems to be a beam. But it is real, and it is a desert for local and immigrant birds crossing the Colorado River Delta. Here, just south of the US-Mexico border, the water used from the city of Mexically gets a second life. Half of it goes to the nearest Hardy River, in an attempt to revive the ecosystem, which was considered unchanged.
Olitically tihassically, the waterways here flashed full of sewer-New rivers especiallyWhich moves north from the Colorado River, enters the United States from Mexico and ends in the Salton Sea of ​​California. For many years, this water course received the sewer not being treated from Mexicly, It is rendering One of the worst-polluted rivers in its size in the United States. In the sixties, the American and Mexican authorities could no longer ignore how bad the problem was, and they started cooperating in infrastructure to reduce pollution. And so, in 2007, the Las Arnitus Treatment Plant started the operation in the south of Mexicale.
Mexicly, which sits right on the border, produces more than 1 million cubic meters of sewage in a year. 90 percent of this total is collected, with 46 percent of it moves to las arenitus.
In the sewer plant, solids and sediments are first removed from waste water. Subsequently, the surface-related lagoons are used, where the air is injected into the air to stimulate the growth of gaseous bacteria, which is the organic matter in the presence of oxygen. The water then moves into the factory lagoons, where aerobic and annerobic bacteria complement each other, subsequently degrades the organic matter that may not be ex. Eventually, the water reaches the maturity lagoon, where the rest of the Sollywood is fixed.
When it was launched, this new system worked. “In the beginning, the plant could not ideally perform,” said Edith Santiago, deputy director of the Colorado River Delta Program in the non -profit Mexicically preservation of the Sonoran Institute. To fight against it, some companies suggested to the water management agency that the surrounding land should be used, which set up a lake a few decades ago, to create an artificial wetland that gives the water over -cleaning.
This national plan, as well as assisting in the city’s sewer problems, will help the local landscape partially recover in its previous state. Prior to excessive explosion of the Colorado River, its Delta Baja crossed California and Sonora until it was combined with the water in the Gulf of California, causing more than 400,000 hectares of wetlands. Although the river course has become a ghost, about 15 percent of the wetlands survive, sheltering plants and animals in an invaluable biodiversity. Wanting to duplicate that energy, Las Arenitus is a break to destroy the artificial wetlands of the local landscape.
