To eliminate the possibility of the effluent (partially treated sewage from your septic tank and drainfield) from leaching into groundwater. Each property is required by County Code to connect to the sewer and abandon their septic tank within one year of being notified of the availability of sewer service.
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.
