Abstract:

Constructed treatment wetlands have become an established technology for treatment of municipal and industrial wastewaters around the world. Wetland systems can provide treatment similar to conventional tertiary wastewater facilities if sufficient land is available but with lower energy and maintenance requirements. Ancillary benefits of treatment wetlands include wildlife habitat, passive recreation, and public education. A 165-acre treatment wetland facility was created by draining, grading, and planting an existing facultative oxidation pond at the City of Stockton Regional Wastewater Control Facility (RWCF) in California during a recent treatment plant upgrade project. The treatment wetland facility is designed primarily to reduce total suspended solids concentrations from upstream ponds and provide additional treatment of biochemical oxygen demand and ammonia-nitrogen upstream of new nitrifying biotowers and tertiary treatment facilities. The mid-process placement of the wetland is designed to manage solids loading to the biotowers and eliminate the need for power-intensive dissolved air flotation for algal solid separation.

The design and sizing of this system was based upon treatment wetland performance modeling calibrated to geographically and climactically relevant data sets from a similarly-loaded treatment wetland system. Initially challenging site conditions resulted in difficulty with wetland construction and startup, but solutions are presented that provide an instructional case study in treatment wetland design and establishment.
