Utility Billing

Pay your utility bill online


Customers registered for the online payment portal will be receiving notification emails from our software provider to inform you that the online payment system has been upgraded and uses a new payment processor.  The email address the message was sent from is noreply@merchanttransact.com  and states you must update your payment information.  You can do this by logging into the system on the link above, “Pay Your Utility Bills Online”

All online payment customers who have stored a credit card in the system will need to update their automatic payment profile. The update is especially important for customers signed up for recurring payments to prevent disruption of your automatic payments.

We apologize for the inconvenience.  Thank you.​


Your City of Redmond water rates are comprised of fixed charges and commodity charges.  It is important to note that water rates will fluctuate, particularly in the summer months, due to increased outdoor water use.

Your water supply comes from wells and water purchased from Cascade Water Alliance.  Water from both sources is treated with chlorine and fluoride and is tested for quality on a daily basis.  Your water has been fluoridated at a rate of one part per million. 

Wastewater & Wastewater Treatment

Maintenance and construction of the local sewage collection system is paid through your city wastewater charge.  The sewer collection system transports sewage from your home to a King County Wastewater Treatment facility.

King County is the regional provider for wastewater treatment and disposal.  Maintenance costs for this collection system are paid by a separate wastewater treatment charge on your bill.


Each developed parcel in the City is subject to the stormwater utility charge.  Drainage from most properties enters or impacts the City stormwater system in some manner.  These facilities, which are generally located on City streets, require continual maintenance and improvement.  The stormwater utility supports capital improvement projects for flood control, erosion, conveyance improvements, and regional water quality or detention facilities.

Stormwater Utility Charge

The utility also monitors the health of local streams, constructs habitat improvement projects, and responds to State and Federal regulatory and permitting requirements.
