UC Davis Wastewater Treatment Plant

Waste Water Treatment Plant

Waste Water Treatment Plant

With over 30,000 students, faculty and staff combined, UC Davis generates approximately 1.2 million gallons of wastewater each day. The Wastewater Treatment Plant (WWTP) in the South UC Davis campus was built in 2000 in order to accommodate the growing campus population and its wastewater production.

A sanitary sewer collection system across the 5,300-acre campus carries wastewater that is flushed or poured down the drain from all campus facilities to the treatment plant for processing. The overall treatment process is made up of six rigorous steps that sanitize the wastewater before releasing it into Putah Creek to minimize our biological and environmental impact.

Putting recycled water to use

Prior to a partnership with the Wastewater Treatment Plant, the Primate Center would purchase new gravel and haul old gravel contaminated with animal waste to the landfill – contributing to the already high tonnage of the campus waste footprint. In an effort to

reduce campus waste, the Wastewater Superintendent Brad Butterfield, along with several colleagues, developed a sanitation system that cleans approximately 10 yards of gravel per day used by the UC Davis Primate Center with clean, recycled water from the treatment plant. The sanitized gravel can be then reused in the animal pens once it passes the Primate Center's lab testing. This innovative, sustainable practice helps the campus reduce its waste and carbon footprint while saving approximately $50,000 per year on cost.
