Wetlands Process

The Stockton Regional Wastewater Control Facility includes wetlands areas totaling 135 acres.  The wetlands area is part of the treatment process that allows the wastewater to be routed through vegetative material that will effectively remove additional material without the use of chemicals. 

There are three ponds with varying water levels that aid in settling materials and remove turbidity, some metals, and biochemical oxygen demand (BOD) through aerobic, anoxic, and anaerobic reactions.  Each year there is a cycle of vegetation decay and regrowth that renews the process. 

Because of the vegetative and sometimes marshy nature of the wetlands, it has also become a distinctive sanctuary for migrating birds.  Throughout the year, a variety of migratory birds can be seen nesting, feeding, and resting at the wetlands.  Please visit our Birdwatching page for more information on scheduling a visit.
