The Simon Fraser University (SFU) Burnaby campus is located at the top of Burnaby Mountain. The campus water system pressure is controlled from an elevated water tower which also provides fire protection and balancing storage. Water is supplied to the reservoir by the City of Burnaby from the Kingsgate Pump Station.
The original pump station was constructed in the 1960's and has been in continuous operation ever since. Prior to upgrading the station consisted of 4x 250 HP pumps, two of which were equipped with right-angle diesel engine drives.
The water supply strategy for SFU includes the addition of a new lower reservoir with a pump station to the existing tower. The Kingsgate pump station will be required to pump to the lower reservoir, while maintaining the capability to pump to the existing water tower.
To facilitate the wide range of operational scenarios, new variable frequency drives (VFD's) were provided to efficiently meet the various flow and head requirements. In addition to the VFD's, upgrades included:
The project was completed while maintaining operation of the station during the entire construction period. This required replacement of the station pumps one at a time and operation on a combination of new and old electrical control systems, until the entire station was converted to new mechanical equipment and power supply.
The engineering team included Empac Engineering (electrical sub-consultant) and Gygax Engineering Associates (structural sub-consultant). Westport Construction was the general contractor for the project.
