Snohomish County provides essential services to safeguard your health and our environment through its stormwater utility, Surface Water Management (SWM), part of the Department of Conservation & Natural Resources. 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.
