The cost varies depending on how much digging is involved and if the residence or business connection has basement facilities. The Environmental Services Department recommends that at least 3 written bids be obtained from licensed sewer excavation contractors. Most residential connections cost in the range of $3,000 to $5,000. If there is significant landscaping or pavement that the contractor is required to restore, the cost can increase substantially.
In addition to the connection costs, each property is required to pay a Capital Facilities Rate (CFR) to Spokane County, which covers a share of the cost of constructing the collection sewers, interceptor sewers, pumping stations and treatment facilities.
As of April 1, 2019 the sewer connection permit fee is $130 plus a $27.12 application fee, for a total of $157.12 for each building connecting to the sewer. A separate sewer connection permit is required for each tax parcel. If each side of a duplex is located on its own parcel, a permit is required for each side. A parcel with multiple buildings will be charged a sewer connection permit fee for each building connecting to the sewer. All buildings on a single parcel can be included on a single connection permit. The sewer connection permit fee and the application fee are subject to future increases.
The Environmental Services Department has records for sewer stub locations and can mail, email, fax or in some instances describe the location over the phone. Drawings of the sewer stub location as well as the sewer pipe connection for the building can be viewed on the Environmental Services website via the Sewer Connections button.

Payments are applied to the oldest unpaid charges.
If the charges on a monthly sewer bill are not paid when due, a one time late payment penalty of 10% of the latest billed amount are added to the charges.
Additionally, interest is attached and accrued on unpaid charges computed at a rate of 8% per annum starting on the next day after the billing due date until paid. Interest is computed on the entire unpaid balance.
Accounts that are in excess of 60 days delinquent may receive a past due statement and delinquency notice. The notice will be mailed to interested parties known to the Environmental Services Department (known parties may include Owner, Mortgage Company, Landlord and Occupant in the case of rental property) regarding the delinquent amount. The delinquency notice will list the amount of charges in arrears, and will explain that the customer must pay the charges within 30 days from the date of the notice to avoid a lien.
The lien will be filed for all delinquent rates, fees and/or charges due in accordance with Spokane County Ordinance 8.03.9040 (Payment-Delinquency-Lien). The lien amount will include late payment penalties together with accrued interest at 8% per annum from the date due until paid. The lien will attach and foreclose pursuant to RCW 36.94.150 and RCW 35.67.215. The County's sewerage lien shall attach for up to one year's delinquent charges without the necessity of any writing or recording of the lien with the County Auditor pursuant to RCW 36.94.150 and RCW 35.67.215. A lien for more than one year's delinquent sewer charges shall attach upon certification of the delinquent charges by the Environmental Services Department to the Spokane County Auditor. The Environmental Services Department may periodically amend these lien certifications.
All costs associated with filing and releasing of a lien, such as filing fees and administrative costs, together with the lien certification amounts, shall be paid to the Environmental Services Department prior to the release of the lien.
The monthly billing statements will show that a lien exists and will give the sum of all charges, for which a lien has been filed. The lien will be released upon payment in full.
Under the Revised Code of Washington, Spokane County may bring a foreclosure action against the property 60 days after the attachment of the lien.
When our crews are cleaning the sewer mains they are using high-pressure hoses that spray water in the sewer main. This can cause high air pressure or negative air pressure in the sewer main and sewer service lines that connect to the house plumbing. If a house does not have adequate sewer vents, which are usually vented through the roof, the excess air pressure can cause water to be blown out of the toilets or p-traps in the home. If your toilet is blown, please contact the equipment operator or call 509-477-1984.
