Hydrant Flow Request

These requests help design fire suppression systems. In some cases, we may have current flow test results that can be provided upon request by contacting spu_dso@seattle.gov. The results provide the water pressure within the distribution system and the pressure during typical demands with no hydrants flowing.

You can now find modeled data for the system capacity of water mains at fire hydrant tee locations on the DSO Water & Sewer Research Map.
