Rafferty Main Dam, Gardiner Dam, and Grant Devine Dam Geotechnical Health Monitoring Upgrades

The Water Security Agency is seeking to upgrade the geotechnical health monitoring systems at Rafferty Dam, Gardiner Dam, and Grant Devine Dam to ensure the continued safety and performance of these critical infrastructure assets. The work involves evaluating the existing instrumentation network, decommissioning non-functional sensors, replacing faulty or outdated equipment, and addressing instruments that are producing inaccurate or alarming data. The goal is to restore reliable, real-time monitoring capabilities that support ongoing assessments of dam integrity, enabling proactive management of geotechnical risks and informing future operational and maintenance decisions. All improvements will align with the agency’s mandate to safeguard public safety and infrastructure under its stewardship. The solicitation, identified as 2026-27-0045, was posted on July 30, 2026, with responses due by August 18, 2026. It is open to qualified contractors and falls under the jurisdiction of the Water Security Agency, a Saskatchewan Crown corporation vested with responsibility for water resource management across the province. All work must be performed within Saskatchewan, and inquiries should be directed to Enrique Aldana, P.Eng., the primary point of contact, via tendersubmissions@wsask.ca. The project reflects WSA’s broader commitment to maintaining the long-term reliability of its dam systems and ensuring compliance with provincial safety and environmental standards.
