Chilled Water Storage Tank

The 90-foot tall tank holds two million gallons of water and is being placed near the University golf course along Perimeter Drive. This is first chilled water storage tank to be installed on the Moscow campus.

The University already has a central chilled water system that consists of two main plants that generate and distribute cool water. Together, the new and existing systems will lead to more efficient air conditioning across campus. Electric centrifugal chillers and steam absorption chillers that utilize steam to generate cold water provide the majority of chilled water for campus use. In the future, individual building chillers will either be decommissioned or connected to the central loop to provide additional capacity.

The project also includes the creation of a third chilled water plant adjacent to the new chilled water tank and the connection of the majority of the campus core to the central chilling system. For now, though, a new chiller tank will be installed to make sure the University can meet its peak load day. An example of a peak load day is when temperatures swelter at 95 degrees with 35 percent humidity. The goal is to make sure air conditioners are in working order in campus offices and classrooms while also protecting laboratories from fluctuating temperatures.

The new chiller tank will serve a critical need on the University of Idaho campus, especially in the research realm. It is a bond-funded project that began in fall 2008.

The project was recently featured on KLEW TV CBS 3 in Lewiston.  The story can be viewed by clicking this link.
