Service Charge

The utilities rate structure is based upon the amount of impervious surface area within each parcel or equivalent service unit (ESU).

An annual service charge of $45 per ESU, shall be levied against each developed parcel within the SWU Service Area.

Billing and Payments

Annual Service Charge bills are included in the same envelope as the Property Tax Statements that are mailed in February. SWU Service Charge payments are due April 30th. 

Service Charge payments are remitted to the Douglas County Treasurer. Please visit the Treasurer's page for information and to make a payment

Example Service Charge Calculations

The following are examples of how ESUs are calculated and applied within the service area:

  • Single family residence equals 1 ESU
  • Duplex equals 1 ESU
  • Tri-plex/Four-plex equals 2 ESUs
  • For all other parcels: Number of ESUs equals the total square feet of impervious surfaces divided by 2,750 square feet (the approximate surface area of an average residential rooftop and driveway)

Please note:

  • No developed parcel shall contain less than one ESU
  • Undeveloped parcels do not contain ESUs
  • Douglas County and East Wenatchee pay for their impervious areas, including streets, roads, trails, and parking lots

Notes

  • Qualified low-income senior citizens and disabled persons may be eligible for a discount.
