- The legal parcel owner/developer, as listed by the County Assessor’s Office
- New parcel owners not listed by the County Assessor’s Office who provide legal documentation that lists them as the parcel owner
NOTE: Washington Water Service will only provide information and documents to the legal parcel owner(s). It is the responsibility of the parcel owner(s) to share information and documents with other interested parties (builders/designers/future owners/permit agencies/realtors).

What is a Non-Refundable Water Availability Analysis Charge?
Effective July 12, 2019, ALL Water Availability Analysis Requests are assessed a Non-Refundable Water Availability Analysis Charge, as specified on Schedule X of our Utilities and Transportation Commission (UTC) approved tariff. Payment should be made payable to Washington Water Service Company and can be made with cash, cashier check, money order, or personal check.
Charges are as follows:
- $20.00 Lender Letter. This letter is only issued to the legal parcel owner(s) for a property sale, stating that the parcel is located within the Washington Water Service area and that the water system can potentially provide water service to their parcel. This letter does NOT include information as to the cost to provide service nor any fire flow information. Lender letters have a 30-day expiration. If additional information is required, such as the potential costs to provide water service to the parcel a Water Availability Analysis Request for Confirmation of Service should be submitted.
- $100.00 Water Availability Analysis. Residential Connections (0-2), Certificate of Water Availability, Confirmation of Service, ADU (Additional/Auxiliary Dwelling Unit, and Fire Flow. Note: Certificates of Water Availability are ONLY issued to the Legal Parcel Owner when applying for a Building Permit and a service connection is set at the parcel. This Certificate WILL NOT be issued for a property sale, unless a service connection is set at the parcel.
- $500.00 Engineering Review. Residential Connections (3 or more), Fire Service (hydrant/in-home sprinklers), Commercial Use, and Plat Development types of projects.
What is the processing time once I have submitted my Water Availability Request?
Upon receipt of the Water Availability Request, payment of the Non-Refundable Water Availability Analysis Charge, and required documents, Washington Water’s Water Availability Request Department will review your request. Requests are processed in the order in which they are received.
We will contact you once we have reviewed your request and provide periodic updates on the status of your request to the email address you provided on your Water Availability Request (unless otherwise noted).
Typical response times are:
- 7-10 business days to review and respond to the Water Availability Request for a residential connection for 0-2 connection(s) that can be directly connected to an existing water main. This includes a lender letter and/or updating an existing Certificate of Water Availability.
- 45 business days if a direct connection is not available or requests are for 3 or more residential connections, fire flow analysis, commercial development, or a residential plat development type of project requiring engineering
During the peak season of April to September, additional time may be required to review and respond to requests.
When will a Certificate of Water Availability be issued?
Certificates of Water Availability are usually issued within 10–15 business days after a service has been installed. A Certificate of Water Availability is only issued to the legal parcel owner once a service connection has been installed on the property corner, any applicable service fees have been paid, and an active billing account is set up.
The parcel owner will be billed a monthly Ready-to-Serve fee (see Washington Water Rate Information-UTC-Approved Tariff) until the service connection has been converted to an active metered service. Effective July 1, 2016, all Water Availability Certificates issued on or after July 1, 2016 are considered a binding contract with Washington Water Service Company. The Ready-to-Serve fee can only be stopped if the parcel owner decides not to connect service and formally relinquishes the connection back to Washington Water or if the parcel owner fails to pay the monthly Ready-to-Serve fee. If the parcel owner fails to pay, the monthly Ready-to-Serve fee Washington Water reserves the right to disconnect and remove the service permanently, returning the service connection to Washington Water. Once a service connection has been relinquished/removed, the parcel owner will be required to resubmit a Water Availability Request and pay the applicable Analysis Charge/Service Connection Charge to set a new service connection. Any fees paid prior to the relinquishment of service are not refundable. Due to changes in available connections in our serving areas, a connection may not be available at the time of the Water Availability request.
