After serving Eugene for over 80 years, the 15-million-gallon (MG) College Hill Reservoir has reached the end of its useful life. EWEB is dismantling the leaky and antiquated reservoir and replacing it in the next few years with new, modern drinking water storage tanks built to withstand major earthquakes. 

Why is this project necessary?

EWEB's College Hill Reservoir—which served all Eugene homes and businesses, and provided emergency water for critical community needs, including fire suppression—reached the end of its useful life and failed to meet current seismic standards. It was unlikely to survive a major earthquake, resulting in Eugene losing critical supplies of safe drinking water in the event of a disaster. 

In addition, the Oregon Health Authority (OHA) required EWEB to rehabilitate or decommission the reservoir because of leaking roof joints. The reservoir also did not drain and fill effectively, which impacted water quality.

Decommissioning the existing facility and building new water storage tanks at College Hill is the most cost-effective solution long-term and will improve water quality and resiliency for all Eugene residents.
