Surface Water Management Division



The Surface Water Management (SWM) Division is responsible for the comprehensive management of the City's man-made surface water systems. This involves protecting developed and undeveloped properties from flooding, runoff and water quality problems, while continuing to accommodate new residential and commercial growth. The SWM Division also promotes the preservation of natural drainage systems and the protection of fishery resources and wildlife habitat.

Services are provided in the form of the following programs: 

The SWM Division provides all surface water and stormwater related services for Federal Way. Please note that SWM is not associated with the two water districts currently providing water and sewer service within the city. Please refer to your water and sewer bill to determine your provider. The Lakehaven Utility District can be reached at 253.941.1516 and the Tacoma Public Water Utility can be contacted at 253.502.8000.
