Steam Distribution Replacement (Veterinary Road)

Reliable steam service is vital for the research sector on campus, so replacing the failing direct buried district steam distribution system that runs between the Western College of Veterinary Medicine and the Vaccine and Infectious Disease Organization (VIDO) was critical to supporting nationally important, world-class research. This line serves the Canadian Light Source, InterVac, VIDO, Animal Resources Centre, POS (Proteins, Oils, Starches) Pilot Plant, and the General Purpose Building.

Steam system failures are not only disruptive, they also result in a great deal of steam condensate loss and potentially dangerous situations. The construction of a 450-metre concrete tunnel to replace the buried steam lines, along with an additional 120 metres of mechanical piping through the basement of WCVM, will decrease energy losses, improve safety and service reliability, save water, and reduce the use of treatment chemicals. The new tunnel and piping through the basement area contain high-pressure steam, high-pressure condensate, and pumped condensate return lines, as well as service chambers to allow access to ancillaries, such as isolation valves, steam traps, and expansion compensators. The size of the steam and condensate lines was also increased to ensure sufficient capacity to serve VIDO/InterVac and potential future developments in this part of the campus.

This project was supported in part by the Knowledge Infrastructure Program.

Construction for this project began in 2010. The new tunnel is now fully operational, but seasonal deficiencies, such as some minor landscaping and small curb/asphalt repairs, will be completed in the spring. Other than these deficiencies, construction was complete by March of 2012.
