Reducing water consumption by 78 percent and cost per trout by 20 percent
The Alberta Ministry of Infrastructure initiated a strategic plan to reduce the operating costs related to source water heating and disinfection at the Cold Lake Fish Hatchery (CLFH), which exceeded C$1 million annually and significantly impacted operational efficiency. The primary objective involved implementing a recirculating aquaculture system (RAS) or a partial RAS to decrease water supply heating demand and open opportunities for energy recovery. They reached out to our team to help.
We evaluated three RAS alternatives to optimize economic feasibility and pinpoint energy-saving modifications. These evaluations led us to discover ancillary benefits such as increased flow to final rearing areas and a reduction in overall rearing duration. Located adjacent to the current hatchery, a new process equipment building houses the RAS equipment and has connections to existing rearing troughs and raceways.
We also modernized the facility’s electrical equipment by replacing the electrical main disconnect and motor control centers, installing a new oxygen generation system, and repairing water headbox leaks. Additionally, we assessed a potential upgrade of the ozone system based on return-on-investment.
CLFH’s revitalization has resulted in significantly reduced operating costs and lower carbon output. The RAS has helped decrease water withdrawal from the nearby lake by 60–80 percent. Today, the project stands as a testament to responsible resource management and progressive aquaculture practices.
