The RMI Teaching & Research Winery at UC Davis is one of the most sustainable wineries in the world, however, wastewater from the winery is currently discharged into the campus sewer system without any treatment. The presence of high levels of nitrogen and BOD (Biochemical Oxygen Demand) makes it challenging for the Water Treatment Plant (WWTP) to process this high load during peak production seasons. This student project proposes designing and implementng an affordable solution for pre-treating winery wastewater using an on-site vermifilter, which involves worms and woody material in an upcycled 275-gallon container. Through this project, RMI can reduce its environmental burden, provide a solution for this important issue, create a valuable project, and offer a full-cycle hands-on educational experience in sustainable innovation for viticulture and enology students.
