Philadelphia Water Department
OUR MISSION
The Philadelphia Water Department and Water Revenue
Bureau serve the Greater Philadelphia region by providing
integrated water, wastewater, and storm water services. The
utility's primary mission is to plan for, operate, and maintain
both the infrastructure and the organization necessary to
purvey high quality drinking water, to provide an adequate
and reliable water supply for all household, commercial, and
community needs, and to sustain and enhance the region's
watersheds and quality of life by managing wastewater and
storm water effectively.

What is a drainage plat map?
Why are they important?
Issues involved with keeping them
current
How can they be improved through
the use of a Geodatabase
Philadelphia Water Department
Drainage Plat Maps (History)





Date back to the 1940’s when they were
maintained as hand drawn linen maps.
Converted to Mylar sheets with a
corresponding index map in the 1970’s
Converted to .tif files in 2001 and are now
maintained digitally.
Full Sets are printed once a year and
distributed throughout the department
4 Years ago the full set was georeferenced
& rubbersheeted


Page Size: 44.5” X 34”
Actual Map Size: 42” X 24.5”
Title Block Size: 42” X 5.25”

What does a Drainage Plat show?







A rough plan view of the entire sewer
system (storm, sanitary & combined)
Size, material, & grade for all sewers
Invert elevations for all manholes
Base map information (hydrology, streets,
facilities, right of ways, railroads, etc.)
Street elevations
Descriptive annotation for specific parts
and aspects of the system
Areas that are currently under construction

Issues Concerning These Maps





Each change to the system is
manually edited within the .tif file.
The base mapping is out of date and
difficult to maintain
New sets are printed out once a year
They changes made are not
georeferenced
They do not fit into our vision of an
Enterprise GIS
