New Utility Rate Changes - to be effective July 1, 2023

The Cornelius City Council approved utility rate changes at their regular meeting on June 5, 2023. The new approved rates are based on the City's need for current and future service and maintenance increases made by Clean Water Services (CWS) for their sanitary sewer and surface water rates. The new approved changes can be viewed by opening the Utility Rate sheet at the bottom of this page.

Sewer Rates and Information

(Last increase - July 1, 2023)
Sewer charges are based on the rates mandated by the Clean Water Services. There is also a City sewer fee.

Residential customers are charged a flat monthly base rate per dwelling unit. Commercial customers are charged based on the number of fixture units being served.

There is also a flat monthly billing for consumption. This is calculated by averaging the amount of water used between the months of November and April. This is the fairest method, since during that time the majority of water entering the house will leave via the sewer system. This rate is calculated every July and is a SET rate for one year.

If you have experienced a leak or some unusual one-time water loss, you may be eligible for a reduction in your winter average figure. Contact the Utility Billing office at (503) 357-9112 to request an adjustment to your sewer average use.

Surface Water Management Rates and Information(SD)

(Last increase - July 1, 2023)
SWM is also a charge mandated by Clean Water Services. There is also a City SWM fee.

Charges are based on the number of Equivalent Surface Units (2,640 square feet of impervious surface). Each ESU is charged a flat rate per month. Under normal circumstances, single family residential homes are billed for one ESU each, all other properties are calculated based on the actual amount of impervious surface.

General Services Fee

(Last rate change on July 1, 2023)
The General Services Fee is charged at a monthly flat rate of $10.50 per dwelling unit for residential homes. Commercial accounts are charged $31.50 per equivalent dwelling unit.
