Name: DWW Mainlines (Probable Flow)

Display Field: MNL_OWNER_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This layer displays all connected or to be connected drainage, sanitary, and combined mainline pipes within the City of Seattle (and the former service area north of the City limits) regardless of ownership and not including detention systems. Probable flow is the derived use classification based on what is the best estimation of usage broken out by combined sewer, drainage, and sanitary. A combined sewer is a type of sewer system that collects sanitary sewage and stormwater runoff into a single pipe system. A sanitary sewer is a type of underground system for transporting sewage . A drainage system transports waste water from buildings and water run-off from streets.
