Surface Water Management

Keeping People Safe and Waters Healthy

Snohomish County provides essential services to safeguard your health and our environment through its stormwater utility, Surface Water Management (SWM). You can see us in your community as we help people fix drainage problems, clean up water pollution and improve stormwater systems. These services are funded by a utility charge paid by people in unincorporated Snohomish County.
