Environmental Services assesses fees on commercial and industrial sewer users that discharge high strength wastewater to the city's sanitary sewer system. Extra strength fees are surcharges above base sewer fees for loadings to the sewer in excess of typical domestic sewage. The fees recover the additional costs of treating high strength wastewater that base sewer fees don't cover.
The city bills extra strength fees for biochemical oxygen demand (BOD) in excess of 300 mg/L, and for total suspended solids (TSS) in excess of 350 mg/L.
Chapter 17.36 of the Portland City Code authorizes extra strength sewer charges.
