Umwelttechnik & Wasserbau

What Umwelttechnik & Wasserbau does

Umwelttechnik & Wasserbau GmbH (U&W) is a privately held German construction company specializing in environmental technology (Umwelttechnik) and hydraulic/water engineering (Wasserbau). Headquartered in Blankenburg (Harz), the firm operates 12 branch offices across Germany and employs more than 850 staff, serving municipal water utilities, public-sector infrastructure clients, and private industrial customers. The company traces roughly six decades of operating history and is organized as a Gesellschaft mit beschränkter Haftung (GmbH) under German law with five managing directors (Jörn Frankenfeld, Camillo Jasper, Thomas Martin, Norbert Wandke, Michael Winkler).

The company's core portfolio spans approximately 17 construction divisions, including Wasserbau (dam/weir/reservoir construction), Umwelttechnik (wastewater treatment plants, environmental protection), Spezialtiefbau (bored piles, driven piles, diaphragm walls, anchor drilling, soil mixing), Rohrleitungsbau (gas/water/district-heating pipeline construction including trenchless methods), Rohr- und Kanalsanierung (CIPP lining and robot-based trenchless rehabilitation), Ingenieurbau (bridges, tunnels), Straßenbau, Erdbau, Hochwasserschutz/Deichbau (flood protection, levees), Speichersysteme, Dückerbau (culverts), Anlagenbau (steel/plant engineering), and an emerging Wasserstoff (hydrogen infrastructure) line. Specialized work is delivered through two wholly owned subsidiaries: U&W Spezialtiefbau GmbH (founded 2018-03-09 in Ermsleben) and U&W Kanalsanierung GmbH (Maintal). Underlying technical capability is anchored in an extensive certification portfolio covering DIN EN ISO 9001/14001/45001/50001, DVGW worksheets GW 301/GW 302/GW 381, AGFW FW 601, Güteschutz Kanalbau (AK1, VP, S10.1, S27.3, S42.2/3), DIN EN 1090-2 (EXC 4), DIN EN ISO 3834-2, AD 2000 HP0/HP100R, RAL-GZ 962/2, and § 19 I WHG.

U&W's commercial model is project-based, sales-led, and executed through direct competitive bidding and direct client engagement rather than channel partners. Revenue is generated primarily through one-time construction contracts for public and private clients, with pricing determined per-project via individualized quotes based on scope and specifications. The company has no disclosed recurring/SaaS revenue streams, no disclosed parent or investor ownership, and operates exclusively within Germany. Customer concentration is skewed toward municipal water authorities and government infrastructure, with named recognition from Kommunale Wasserwerke Leipzig GmbH (TOP-Lieferant award, 2012–2014 performance period). Marketing is conventional B2B — corporate website, social media (Instagram, Facebook), and certification-led trust signaling — supplemented by industry association membership (e.g., DVGW).
