The University of Guelph upgraded and expanded its heat-recovery system to improve energy efficiency. The system was reconfigured to use the heat released by the stack at Central Utilities to heat water that is delivered in pipes to the buildings on campus. The water is used in academic, research and residence spaces and accounts for an estimated 3,200 tonne reduction in greenhouse gases.

Roberts Onsite completed the mechanical scope of the project, supplying and installing approximately 1,000' of 12" diameter pipe and 2,200' of 8" diameter pipe, complete with insulation. The pipe was carbon steel, SCH 40 with welded connections.

We were responsible for the fabricated supports and pipe expansions that were accommodated through the application of anchors, guides and flexible connectors. To expedite the work, the valve stations were fabricated at our in-house fabrication shop and transported to site for installation.

Once the installation was complete, the piping system was pressure tested and chemically flushed. The project was completed while the facility remained fully operational with minimal impact on the occupants.
