Effluent - fully treated influent flowing from the SW Clean Water Plant to Wilson's Creek.
% Removal of Influent Loading - SW Clean Water Plant is required to have a minimum of 85% removal efficiency on a 30 day average of BOD, TSS, and Ammonia.
Biochemical Oxygen Demand (BOD) - measure of the amount of oxygen required to biologically stabilize a waste stream. NPDES Permit limit for Effluent is 10 mg/L.

Total Phosphorus (TP) - essential chemical element and nutrient for life forms. TP is a Government regulated nutrient which requires removal to prevent degradation of receiving streams. NPDES Permit limit for Effluent is 0.5 mg/L.
Fecal Coliform - pathogenic bacteria commonly occurring in wastewaters. NPDES Permit limit for Effluent is 400 coli/100 mL As of October 2014 the SW Plants NPDES permit changed to monitoring Escherichia Colifom.
Escherichia Coliform (E. Coli) - a genus and species of the fecal coliform bacteria group. E.Coli is present in the intestines of warm-blooded animals and humans. NPDES Permit limit for Effluent is 126 coli/100 mL As of October 2014 the SW Plants NPDES permit changed to monitoring Escherichia Colifom.
