BGS UMWELT

What BGS UMWELT does

BGS UMWELT (Brandt Gerdes Sitzmann Umweltplanung GmbH) is a privately held German engineering and environmental planning consultancy founded in 1984 in Darmstadt-Eberstadt, where it is headquartered at the historic Eschollmühle estate. The firm delivers integrated consulting services across six practice areas — groundwater management, water supply, waste management, contaminated sites, ecology, and geoinformatics — covering the full project lifecycle from conception and permitting through to realization and construction supervision. It is led by three managing shareholders (Dr.-Ing. Heiko Gerdes, Dipl.-Ing. Egbert Graf, and Dr.-Ing. Markus Kämpf) and operates with a team of approximately 20 interdisciplinary professionals comprising civil engineers, geologists, geographers, geoecologists, technicians, and draftsmen.

The firm's technology stack rests on three proprietary layers. First, Grundwasser-Online — conceived in 2000 and maintained since — is a cross-company and cross-authority groundwater monitoring and management platform consolidating data from over 7,500 monitoring objects across the Hessisches Ried region, including wells, infiltration organs, springs, climate stations, and gauges. Second, the firm develops and applies computer-aided simulation models across groundwater, soil water, and geothermal modelling, including 3D transient groundwater models calibrated against climate data from 1960 onward and used for forecasting through 2100. Third, a geoinformatics capability built on GIS and CAD systems supports remote sensing, GIS analysis, web mapping, and full digital planning-data processing. These capabilities are reinforced by two jointly controlled subsidiaries: Geoventis GmbH (founded 2001 with UNGER ingenieure and Planungsbüro Koch for GIS services) and envi-systems GmbH (founded 2006 with CIP Ingenieurgesellschaft for environmental informatics and software development).

BGS UMWELT operates a sales-led professional services model, generating fee-based revenue through tailored engineering and environmental planning engagements under non-publicly disclosed project pricing. Its client base comprises water supply companies, municipal authorities, public institutions, and government bodies — with named customers including five water utilities in the Hessisches Ried region, Hessenwasser GmbH & Co. KG, Regierungspräsidium Darmstadt, and the Hessisches Landesamt für Umwelt und Geologie. The firm participates in multiple BMBF-funded research initiatives (WaRM, Nutzwasser, TrinkWave, AnKliG, KORA), which both diversify its funding mix and reinforce its positioning as a research-linked consultancy serving the German water and environmental infrastructure market.
