SPU Proposes to Update Charges for Development-related Services on January 1, 2026
Seattle Public Utilities (SPU) plans to update charges for development-related services, including water service installations (“taps”), water main extensions and improvements, and others.
Charges are being updated to reflect the actual costs for SPU to provide these services in 2026 and ensure that Seattle ratepayers are not subsidizing these individual services.
To update separate charges, SPU will need to adopt a Director’s Rule. The public can comment on the rule during a formal comment period, which ends on November 17, 2025.
If the director’s rule is adopted, revised charges will become effective on January 1, 2026.
