Project Information

Oceanis is part of the design team for the City of Regina’s new Indoor Aquatic Facility (IAF), one of the largest aquatic centres in North America. The project is planning to use deep geothermal energy to help transition the facility away from fossil-fuel dependency and align with the City’s renewable ambitions.

Facility Overview

Heating a major public aquatic facility in one of Canada’s coldest cities without relying on fossil fuels is not a small engineering challenge. Regina’s new Indoor Aquatic Facility (IAF), among the largest aquatic centres in North America, is addressing that challenge directly by planning to use deep geothermal energy as its primary heat source. Oceanis leads the surface infrastructure design, responsible for connecting subsurface geothermal resources to the facility’s pool heating, HVAC, and building services.

Oceanis Role — Geothermal System Infrastructure Design

Oceanis was engaged to deliver the geothermal system infrastructure design and aquatic centre integration for the City of Regina’s new aquatic facility and acted as the lead designer for geothermal surface infrastructure and for system integration. Oceanis’ role focuses on ensuring reliable and efficient thermal performance, constructability, and coordinated integration with the sub-surface systems, the building HVAC systems, pool heating systems, and overall integration of the geothermal systems into a complex building and a constrained site.

Outcomes & Impact

The project supports the City of Regina’s objective to reduce reliance on fossil fuels for aquatic facility pools and building heating by applying deep geothermal energy in a cold-climate municipal context, while strengthening delivery confidence through coordinated integration between geothermal infrastructure and facility services.

The design process has generated sufficient technical depth that Oceanis is developing findings into a paper for presentation at the World Geothermal Congress 2026 in Calgary — a marker of the project’s significance within the field.
