Requesting Hydrant Flow Test

Contact a Seattle Public Utility (SPU) Utility Service Team to assist you in obtaining hydrant flow information. Call (206) 684-5800

 SPU provides these options for obtaining hydrant flow information:

  • Hydrant Flow Test (performed by SPU) - $2,002
  • Hydraulic Analysis Report - $2,000 deposit, billed actual time and materials
  • Hydraulic Modeling Simulation Report $407

Note: Hydrant testing is often scheduled at night when the surrounding community is least likely to be affected by the test. You can expect to see turnaround times ranging between 4-6 weeks, depending on the workload at the time of the request.
