The JWC stores 40 million gallons (MG) of treated drinking water on Fern Hill. These 20 MG reservoirs are two of the largest potable water tanks in Oregon.

Fernhill Reservoir #1 was first completed in 1982 at a cost of $3.3 million. Fernhill Reservoir #2 was completed in 2006. Including rehabilitation of Reservoir #1, the project cost was $17.4 million.

Reservoir #2 is wrapped in 141 miles of cable, enough to stretch from Fernhill all the way to Cottage Grove, Oregon. The cable machine wrapped the reservoir at a rate of 2 MPH.

Prior to its recent rehabilitation, Reservoir #1 had never been taken off-line in 25 years. Occasional inspections on the tank were performed by specially-trained scuba inspectors.
