This upgrade was SaskWater’s first significant project using the design build process, which brings an engineer and contractor into the project early in the planning process. This approach provides more cost certainty prior to construction, which is especially helpful when seeking funding from grant programs.
The team is provided with an outcome, performance requirements, and a budget for the project, and then they collaborate on the most effective solution.
“With this approach, the relationship between owner, contractor and engineer is much more harmonious,” said Chris Robart, Manager, Construction Engineering at SaskWater. “It’s always better to have more minds working on something.”
The system upgrades included a new clarifier, additional filters, and backup power. Having multiple clarifiers reduces the workload on each unit and allows them to be taken offline for periodic maintenance and cleaning.
“These upgrades will allow us to treat the water while performing preventative maintenance tasks, or even when the power goes out,” explained Brad Dunlop, SaskWater Account Manager. “This will improve the reliability and safety of the potable water supply and reduce the number of service interruptions on the system.”
The backup power helps to prevent Precautionary Drinking Water Advisories (PDWA) on the system. A PDWA is required if a power outage causes the regional pipeline to depressurize, creating the potential for contamination.
“The upgrades will improve the efficiency and effectiveness of the water supply infrastructure while supporting future economic development and community growth in the region,” Robart said. “Overall, the project is a complete success.”
