Utilities—Water FAQs

  • How is UC Davis water treated?
  • The campus’s domestic water is not treated, except for disinfection using chlorine (sodium hypochlorite). Chlorine levels are typically maintained at 0.5 ppm (parts per million).
  • Does UC Davis recycle water?
  • UC Davis makes limited use of its highly treated wastewater effluent. The water meets all standards for unrestricted use. Currently, only the grounds of the Wastewater Treatment Plant itself and the surrounding area are irrigated using reclaimed water.
  • What can I pour down the drain?
  • The Utilities Department has provided an infographic of what you can pour down the drain. 
  • Where can I get information about the campus drinking water quality?
  •  As a public water supplier, we prepare annual “Consumer Confidence Reports” with considerable detail about our water quality. Campus Water Quality Reports are published on the Utilities website.
  • Where does UC Davis get its water?
  • UC Davis runs its own domestic water system. Six on-campus wells are used as the University’s domestic water supply. These wells draw water from aquifers 800 to 1400 feet below the ground.  Shallower wells are used to provide irrigation water for the campus.  Additionally, the campus purchases surface water from the Solano Project for field teaching and research, primarily in the West and South Campuses.
