Eberhard & Partner

What Eberhard & Partner does

Eberhard & Partner AG is an independent, employee-owned geological and environmental consulting firm headquartered in Aarau, Switzerland. Founded in April 1994 by geologist Mark Eberhard, the firm has operated for over 30 years in geology, engineering geology, environmental, and energy technology, and was transferred to five long-standing employees in October 2020, with Iris Marschall and André Schwarzer now leading management. The company serves property owners, municipalities, healthcare facilities, industrial clients, and research institutions across multiple Swiss cantons (Aargau, Zürich, Solothurn, Schaffhausen, St. Gallen), accumulating more than 810 ground source heat pump and 400 groundwater heat pump projects over its history.

The firm's service portfolio spans three pillars: Geothermie (ground source heat probes, groundwater heat pumps, deep drilling), Umwelt (contaminated site assessment, soil investigation, water testing), and Ingenieurgeologie (building ground, crack documentation, flood protection, drinking water, protection zones). Core technical capabilities include the proprietary DeepDrifter® borehole surveying system (registered trademark), which provides spatial measurement and temperature profiling of ground source heat exchangers, and the application of third-party simulation software — Earth Energy Designer (EED), Modflow/Feflow, and Groundwater Energy Designer (GED) — for modeling 50-year thermal performance and groundwater impacts per SIA 384/6 standards.

The business model is project-based professional services delivered via direct consulting engagement with enterprise and mid-market clients across Switzerland. No public pricing is disclosed; engagements are quoted individually. The firm has no external investors, no parent company, and no channels beyond direct sales. Notable enterprise clients include Children's Hospital Zürich, Cantonal Hospital Aarau, Schloss Wildenstein, Migros Aare, Siegfried AG, ewz, EMPA/Eawag, and IBB Energie AG. Revenue is not publicly disclosed and headcount is reported in the 1–10 range.

Core offering

Eberhard & Partner AG is a Swiss geological and environmental consulting firm that delivers project-based services in geothermal system planning (ground source heat probes and groundwater heat pumps), environmental contamination assessment and remediation support, engineering geology investigations, and water resource management (flood protection, drinking water, protection zones). Services span feasibility studies, permitting, construction supervision, quality assurance via the proprietary DeepDrifter® borehole surveying tool, and computer-based simulation (EED, MODFLOW/FEFLOW, GED). Clients are municipalities, property developers, industrial firms, healthcare facilities, and energy providers across multiple Swiss cantons.

Product overview

EBERHARD & Partner AG is an independent, owner-managed geological and environmental consulting firm based in Aarau, Switzerland, offering a portfolio of interrelated services in geothermal energy, groundwater management, environmental engineering, and engineering geology. The portfolio is organized into three interlocking pillars: Geothermie (Erdsonden, Grundwasser-Wärmepumpen, Tiefbohrungen), supported by the proprietary borehole survey tool DeepDrifter® and modeling services (Earth Energy Designer, MODFLOW/FEFLOW, Groundwater Energy Designer); Umwelt (Altlasten/Gebäudeschadstoffe, Boden, Wasseruntersuchung); and Ingenieurgeologie (Baugrund, Beweissicherung/Rissaufnahmen, Hochwasserschutz, Trinkwasser, Schutzzonen). The DeepDrifter® is the firm's own branded measurement product, while the modeling tools (EED, GED, MODFLOW/FEFLOW) are third-party simulation software packages the firm applies as a service to optimize geothermal system design and groundwater usage.
