Water for the campus is purchased from the City of Pittsburg at a usable pressure so that it is not necessary to "re-pump" the water to maintain working pressure.
The university has adopted a policy of strict adherence to city pretreatment ordinances that specify substances that cannot be poured or flushed down the sanitary sewer. A copy of this ordinance is on file at the Physical Plant and has been distributed to all departments.
Tests have been conducted to identify any potential cross-connection between the storm and sanitary sewer that could cause mixing of sewage and runoff during periods of heavy rainfall. None have been identified, and any backup of water is considered to result from hydraulic overload in the city's nearby interceptor sewer.
The sewer system on campus is owned by the university and maintained by the Physical Plant. Sewage from the campus is discharged into the city sewage system at the perimeter of the campus. The university pays a monthly charge to the city for handling sewage.
