Wetlands ProcessWetlands

The Stockton Regional Wastewater Control Facility includes wetlands areas totaling 135 acres.  As part of the treatment process, the wetlands area allows wastewater to flow through vegetative material to remove additional material without the use of chemicals. 

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

The vegetative and sometimes marshy nature of the wetlands also offers a sanctuary for migrating birds.  Throughout the year, a various migratory birds can be seen nesting, feeding, and resting at the wetlands.  Please visit our bird watching page for more information on scheduling a visit.
