Heating for Washington State University's Pullman campus is provided by a central steam plant connected
to 120 campus buildings through more than 18 miles of steam and condensate piping in 6.5 miles of tunnel.
Washington State University called on Wood Harbinger to optimize the system and to integrate it with a new energy plant.
Wood Harbinger first completed an extensive survey of the steam distribution system. The information gathered
contributed to an innovative solution to consolidate the separate 200 psi high pressure and 60 psi
low pressure distribution systems into a single 100 psi steam system.
Consolidating the two systems saved $2 million of capital resources, provided a more manageable system,
and, in the words of Richard Zilar, P.E., Project Manager for the University, "...established Washington State
University as a model for creative problem solving in similar campus infrastructure systems."
