How Environmental Services Invests Sewer Charges

Where does your rate money go?

Portland sewer rates increased on July 1, 2016, the start of the city's 2016-2017 fiscal year. The average monthly sewer bill for single family residential sewer customers went up $2.20, or 3.25%. The 3.25% rate increase makes Portland's average monthly residential bill for sewer and stormwater services an estimated $69.80. Debt Service for Sewer and Stormwater infrastructure (mentioned above) accounts for about 49.7% or $34.68 of the average monthly bill.
