The University has a holistic approach to stormwater and wastewater management, as well as potable source water protection
The following presentation will focus on the University's water resource efforts of continual improvement for a sustainable strategy
OPP Stormwater Management Training and Education Series
From a stormwater management perspective, the Universitypromotes foremost the use of conservation design practices that preserve and
use natural critical hydrologic areas, but it does have structural BMPs too

The University holds dozens of water quality permitsfor each of its systems in 5 of the major state basins, including 11 small
Municipal Separate Storm Sewer System Permits

The University Park stormwater collection systemincludes over 73 miles of storm drains ranging in size from 6” to
72” in diameter

At University Park, the University has about 460 acresof imperviousness in the main campus area
OPP Stormwater Management Training and Education Series
However, not all imperviousness creates surface runoff. For example, Old Main, and several other buildings have always drained directly to
drywells and or cisterns.

The wastewater treatment plant includes a land treatment area (606 acres), which has discharged no effluent to surface waters
for the last three decades, known as the living filter

At University Park, the University is its own potable waterpurveyor, supplying over one billion gallons annually to its customers

The University is committed to the wise stewardship of our water resources
Since 2004, OPP has instituted a program to further reduce energy and potable water consumptive use on campus. For example, in fiscal year 2007/08, the program saw an annual reduction of 33.4 million gallons
OPP Stormwater Management Training and Education Series
The University has identified potential reuse customers and installs reuse pipe (purple pipe) at new projects for future use
as another way to conserve its potable water

The University Park Campus is divided between the Big Hollow and Thompson Run/Slab Cabin watersheds, which are
significantly different from a hydrologic perspective

with no perennial or intermittent surface streams)

The University pumps ground water from its two well fields
Houserville Well Field(harder water)

Wastewater is sent to the University’s treatment plant where it is properly treated

After treatment, the secondary effluent is sprayed at the living

Most of the University’s developed land areas are within four major drainage basins, which are managed differently based on
the local soils, geology, and stream classification

stormwater management facility (not even including the Duck Pond or Millbrook Marsh)

OPP has also instituted an extensive surface water monitoring project with over 50 permanent gages, which collect continuous
data at 5 to 15 minute intervals
OPP Stormwater Management Training and Education Series
Data and studies can be found on the University’s website at:http://www.opp.psu.edu/services/stormwater/presentations-publications

The University has established a Water Resources Preservation land use classification (blue shaded areas below) for
approximately 455 acres of its land at University Park

Recharge areas are aggressively protected . The Mitchell Tract recharge area, now located within the Arboretum, fully infiltrates a 100-year runoff event and consists of two closed depressions, one natural and one artificial.

Because the entire University Park Campus is underlain by carbonate geology, sinkholes are an operational way of life; however, the
University is sensitive to practices that make them occur more often.

Therefore, at University Park, the artificial injection of surface runoff into subsoil is not used or promoted by the University and recharge
areas are kept away from infrastructure due to the carbonate geology
