After serving Eugene for over 80 years, the 15-million-gallon (MG) College Hill Reservoir has reached the end of its useful life. EWEB will dismantle the leaky and antiquated reservoir and replace 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 serves all Eugene homes and businesses, and provides emergency water for critical community needs, including fire suppression—is nearing the end of its useful life and fails to meet current seismic standards. It is 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) is requiring EWEB to rehabilitate or decommission the reservoir because of leaking roof joints, which creates the potential to degrade the water quality. And from an operations standpoint, the College Hill reservoir does not drain and fill effectively, which impacts 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.
