Stormwater is water that does not permeate the ground but instead runs over impermeable surfaces like roofs, parking lots, and streets, picking up pollutants and debris before finally entering the storm sewer system. Much of this untreated water eventually enters creeks, streams and rivers. The table below shows stormwater management technologies, their purpose and where they are in use on the OSU campus.
The City of Corvallis has stringent regulations and guidelines related to stormwater.
A recent assessment on our campus's stormwater quality was done by OSU students. Results showed high levels of zinc and nitrate and acceptable levels of turbidity and conductivity. Analysis to OSU stormwater is important because it can help to improve the quality of the creek that it flows into (Oak Creek). The analysis also provides a basis to help OSU eventually become stormwater independent, meaning that we can reuse and treat the water on campus.

Kelley Engineering Center
The Kelley Engineering Center is one of several buildings on the Oregon State University Corvallis campus that has a Gold LEED certification from the U.S. Green Building Council. This certification was awarded for an abundance of sustainable features, several of which help treat water more sustainably and reduce potable water consumption. From native plant beds that act as biofilters to permeable paving that minimizes storm runoff, to a 16,500 gallon rainwater capture system, Kelley’s water systems contribute to it being one of the greenest academic buildings in the nation. The rainwater captured at Kelley is used throughout the building for toilets and urinals, allowing the building to minimize its outsourced utility needs. See more about Kelley here.
