This Artificial Wetland Is Reusing Wastewater to Revive a Lost Ecosystem
Las Arenitas is an artificial oasis that recycles used water from the border city of Mexicali to regenerate ecosystems in the Colorado River delta.
Construction of the wetlands began in 2009, a collaboration between the federal and state governments, water agencies, and investments obtained by the conservation nonprofit Pronatura Noroeste and the Sonoran Institute. It’s possible to smell when the wetland ecosystem is out of kilter: The decomposition of organic matter there can generate unpleasant odors when these systems are under stress or out of balance, giving the environment an earthy, pungent aroma. An assessment of ecosystem services provided by the wetlands in the arid zone of Mexicali, published in 2023, highlighted the system’s high potential for regulating water flows, promoting environmental education, and recharging the local aquifer.
