Abstract:

This layer is dissolved and queried from PWD's internal sewer shed feature class named, modlesheds. The polygons in this layer are catchments for sanitary, storm and/or combined sewer flows. These catchments are used in the hydraulic models.Data DevelopmentBase Modelsheds are maintained regularly and delineate waste water and stormwater and combined sewer catchments in Philadelphia. Storm water and waste water pipe flow are analyzed to delineate the shed boundaries.Coordinate systemNAD_1983_StatePlane_Pennsylvania_South_FIPS_3702_FeetProjection: Lambert_Conformal_ConicFalse_Easting: 1968500.000000False_Northing: 0.000000Central_Meridian: -77.750000Standard_Parallel_1: 39.933333Standard_Parallel_2: 40.966667Latitude_Of_Origin: 39.333333Linear Unit: Foot_US (0.304801)Geographic Coordinate System: GCS_North_American_1983Angular Unit: Degree (0.017453292519943299)Prime Meridian: Greenwich (0.000000000000000000)Datum: D_North_American_1983Spheroid: GRS_1980Semimajor Axis: 6378137.000000000000000000Semiminor Axis: 6356752.314140356100000000Inverse Flattening: 298.257222101000020000Other InformationFeel free to contact me with any questions or to point out errors.

Entity_and_Attribute_Overview:

The attribute "Collector" and "Variable" were created so the sheds could be grouped for slope analysis.  The "Variable" is a four character abbreviation of "Collector".  3 of the groupings Poquessing, Southwest Main Gravity & Upper Delaware Low Level have a slight variation of the variable.  These are tagged with an I on a 3 character prefix for inside the limits of the City data.  So Poquessing is POQI, Southwest Main Gravity is SMGI & Upper Delaware Low Level is UDLI.
