W.E.T. Schaper GmbH

What W.E.T. Schaper GmbH does

W.E.T. Schaper GmbH is a privately held German water hygiene services company founded in 1953 and headquartered in Adelhausen, Baden-Württemberg, with a wholly owned Swiss subsidiary (W.E.T. Schaper Suisse GmbH, Zeiningen). The company provides on-site cleaning, disinfection, descaling, inspection, and maintenance services for water-carrying and ventilation systems — including drinking water tanks, filtration systems, wells, evaporative cooling systems (VDI 2047-2), wet scrubbers (VDI 3679), cooling towers (42nd BImSchV), heat exchangers, and HVAC/air handling units — serving water utilities, industrial facilities, drinking water installation operators, commercial property managers, and maritime/ship operators. Services are delivered by trained field personnel who travel to customer sites across Germany, Switzerland, Austria, the Netherlands, Hungary, Slovenia, Denmark, Cuba, Dubai, and at sea, providing regulatory compliance documentation for health authorities and certification under VDI, DIN, and BImSchV frameworks.

The company's product backbone is a portfolio of in-house developed proprietary cleaning agents formulated for water hygiene applications, sold both directly and as private-label manufactured goods for water utilities, industrial sites, and fountain maintenance. A complementary training and certification practice covers VDI 6023-C, 42nd BImSchV, DIN 19606, DIN 19643, BGVA/GUV guidelines, chlorine/chlorine dioxide applications, and swimming pool hygiene. The business model combines professional services revenue (project- and contract-based), one-time product sales (including private-label), and training fees. GTM is enterprise field sales supported by an inbound inside-sales team, with demand generated through trade shows (Maintenance 2026, ÖVGW, Trinkwassertagung), industry associations, and downloadable catalog content from the company website. The company is family-led (Managing Director Susanne Schaper), self-describes as a "kleines mittelständisches Unternehmen," recently relocated HQ after a two-year planning project, and is actively hiring operational staff across five German locations.
