Overview of the Sewer Connection Process
Connecting a private building to Seattle's public sewer commonly requires coordination between Seattle Public Utilities (SPU) for sewer service and the Department of Construction & Inspections (SDCI) for permits and inspections. Typical steps include submitting permit applications, paying connection and inspection fees, scheduling inspections, and completing required restoration work in the public right-of-way.
Key administrative contacts are the SDCI permit center and SPU customer services for sewer connections and billing.[1][2]
Required Permits and When to Apply

- Obtain SPU authorization and any needed utility permits for work in the public right-of-way, including excavation or restoration.
- Submit permit applications before construction starts; allow time for plan review and scheduling of inspections.
Fees, Charges, and Typical Costs
- Connection charges and permit fees vary by project scope and location; specific fee amounts are published by SPU and SDCI on their official pages.[2]
