OSU Annual Water Quality Reports

Oklahoma State University Water System PWS 1020910

Annual Water Quality Reports keep our customers informed about the water quality and services we have delivered over the past years.  Our goal as always is to supply Oklahoma State University with a safe and dependable supply of quality drinking water.

 Water Being Poured

OSU Stillwater is supplied potable water by the OSU Water Treatment Plant located west of campus at 226 South Pioneer.  The Plant’s raw water source is Lake Carl Blackwell, located approximately 6 miles west of Stillwater. Throughout 2020, the Water Treatment Plant supplied approximately 403,174 million gallons of drinking water to the campus. 

The OSU Water Treatment Plant routinely monitors for numerous constituents in the drinking water according to Federal and State laws.  We also participate in USEPA efforts to continually research methods to improve the effectiveness of water treatment and delivery.
