Sewer Rates

Redmond's municipal wastewater system conveys and treats an average of 1.7 million gallons per day (mgd) of domestic, commercial, and industrial wastewater.  The city’s modern treatment plant is designed for an average daily flow of 3.0 mgd, resulting in excess capacity of 1.3 mgd. Further, the City of Redmond has the ability to add additional capacity within the existing treatment plant should a project warrant it.

Commercial and industrial accounts pay a base fee per month for the first 700 cubic feet (cf) of water used, plus a volume charge based on the strength of wastewater discharged for water use exceeding 700 cf. The volume charge is calculated using an average of winter months’ (December- April) water use.

Storm Water Rates

Redmond’s Storm Water Program provides for the management of both the quantity and quality of storm water runoff from public facilities in order to prevent local flooding and protect the quality of groundwater supplies. This is accomplished through the operation and maintenance of 1,700 drywells and drill holes, 3,600 catch basins, 33 miles of pipe, and street sweeping 314 lane miles of city streets.  Water quality sampling and reporting is also performed to maintain compliance with state and federal regulatory requirements.                                               

Commercial and industrial accounts pay a base fee per month plus a variable fee based on the average number of daily vehicle trips generated by the site.  The daily trips are calculated using the Institute of Transportation Engineers Trip Generation Manual.
