Data Description

Sewer Utility Data includes the basic components of the City of Bellingham's sanitary sewer system. The data has been symbolized and color coded with mapping parameters conveniently pre-set.

Layer File Details*

Catch Basin  (metadata)
Description: This point feature class is a collection of sewer catch basins found in the City of Bellingham's sanitary sewer system. Catch basins prevent clogging of sewers by sediment and debris washed off streets and other surfaces, and provide a water seal against the venting of sewer gases. At this time we do not have record of existing sewer catch basins, and it is not anticipated that there will ever be any in use within the City of Bellingham (per Engineer Martin Kjelstad).
Symbology: All points are symbolized using a "single symbol" set. Catch basins are shown as green squares.
Labels: The labels represent each catch basin's unit ID number, and is derived from the "unitid" data field.
Definition Query: None

Clean Out  (metadata)
Description: This point feature class is a collection of sewer clean outs found in the City of Bellingham's sanitary sewer system. A sanitary sewer cleanout is installed at the end of a segment of sanitary sewer main to allow for access to maintain the pipe.
Symbology: All points are symbolized using a "single symbol" set.  Clean outs are shown as green circles with a cross.
Labels: The labels represent each clean out's unit ID number, and is derived from the "unitid" data field.
Definition Query: None

Manhole  (metadata)
Description: This point feature class is a collection of sewer manholes found in the City of Bellingham's sanitary sewer system. Sanitary sewer manholes allow maintenence access to the sanitary sewer system.
Symbology: All points are symbolized using a "single symbol" set.  Manholes are shown as green circles.
Labels: The labels represent each manhole's unit ID number, and is derived from the "unitid" data field.
Definition Query: None

Fitting  (metadata)
Description: This point feature class is a collection of sewer fittings (cap, tee, cross, etc.) found in the City of Bellingham's sanitary sewer system. Individual sewer fittings may serve to close off a sewer pipe end or may connect sewer pipes to one another.
Symbology: All points are symbolized using a "single symbol" set.  Fittings are shown as green crosses.
Labels: The labels represent each fitting's unit ID number, and is derived from the "unitid" data field.
Definition Query: None

Gravity Main  (metadata)
Description: This polyline feature class is a collection of sewer gravity main lines found within the City of Bellingham sanitary sewer system. Sewer gravity mains are pipes that transport wastewater that flowing downhill.
Symbology: There are three seperate symbols that indicate whether the gravity main is City of Bellingham or Privately maintained, and if it is under construction.  These symbols are based on combinations between the "AdministrativeArea" and "LifecycleStatus" data fields. A solid green line with flow direction arrow symbolizes gravity mains that are "active" (not under construction) and maintained by the City of Bellingham. A green line with round dots symbolizes gravity mains that are under construction and that will be maintained by the City of Bellingham when they become "active." A green dashed line symbolizes gravity mains that are "active" and maintained privately. Gravity mains that are under construction that will be privately maintained are not symbolized in this layer file.
Labels: The labels represent each manhole's unit ID number, and is derived from the "unitid" data field.
Definition Query: None

Pressurized Main  (metadata)
Description: This polyline feature class is a collection of sewer pressurized main lines found within the City of Bellingham sanitary sewer system.  Sewer pressure mains are pipes that transport wastewater that is forced to flow uphill under pressure.
Symbology: There are three seperate symbols that indicate whether the pressure main is City of Bellingham or Privately maintained, and if it is under construction. These symbols are based on combinations between the "AdministrativeArea" and "LifecycleStatus" data fields. A green and white line with flow direction arrow symbolizes pressure mains that are "active" (not under construction) and maintained by the City of Bellingham. A green line with square dots symbolizes pressure mains that are under construction and that will be maintained by the City of Bellingham when they become "active." A green line and white dashed line symbolizes pressure mains that are "active" and maintained privately. Pressure mains that are under construction that will be privately maintained are not symbolized in this layer file.
Labels: The labels indicate the diameter, material, and year of installation of the pressurized main pipe.
Definition Query: None

Lateral Line  (metadata)
Description: This polyline feature class is a collection of sewer service lines found within the City of Bellingham sanitary sewer system. Service ("lateral") lines are privately owned and provide a connection to the sanitary sewer system. This data, as a whole, is not considered to be highly accurate.
Symbology: All lines are symbolized using a "single symbol" set. Lateral lines (service lines) are shown as dashed green lines.
Labels: None
Definition Query: None

Eden Customer Sewer Service
Description: This point provide a spatial view of sewer customers from Eden data records in the City of Bellingham sanitary sewer system.
Symbology: A green dot symbolizes each sewer customer record filtered from Eden records as defined in the definition query below.
Labels: Labels indicate the Eden customer account number based on the UnitID field.
Definition Query: SEWER_DESC is not NULL, blank or coded as "No Sewer Service"

Sewer Basins
Description: This polygon feature class consists of defined areas where the sanitary sewer system contributes flow to each trunk sewer main in the City of Bellingham sanitary sewer system.
Symbology: All polygons are symbolized using a "single symbol" set. Sewer basins are shown as gray polygons.
Labels: The labels indicate the name of each sewer basin based on the "name" data field.
Definition Query: None
