Critical Operations Energized by Geothermal

Olmsted County Public Works houses an immense amount of equipment for all kinds of public operations. This facility is critical for doing the O&M on all assets and being ready to deploy for critical events like large scale snow removal, natural disaster mitigation, and every day events like road grading or tree removal as well.

Driven by a desire for innovation and fiscal responsibility, the Olmsted County Public Works is part of a broader county wide approach to sustainable, long lasting public infrastructure. This project targeted a mechanical design that used geothermal to improve energy efficiency to meet state wide standards.

Originally using a pond water geothermal system, over the 15 years of operation it became evident additional space for employees necessitated an expansion of the facility and thermal capacity along with it. The project also has multiple EV chargers on site and combines a modern and functional building aesthetic with a natural surrounding of the Southeastern landscape of Minnesota.

Investing in Sustainability for the Future

Darcy Solutions built a 2-well, 51-ton geothermal system for this municipal infrastructure hub. The aquifer-based design and well heads subtly blend into the natural environment around the facility and the beautiful pollinator friendly prairie of the site.
