AT Trinkwasserhygiene

What AT Trinkwasserhygiene does

AT Trinkwasserhygiene is a sole-proprietorship drinking-water hygiene service provider headquartered in Putzbrunn, near Munich, Germany, with six employees. The company performs professional water sampling and laboratory-coordinated analyses in compliance with the German Drinking Water Ordinance (TrinkwV 2001), including periodic Legionella testing for commercial and large residential installations, microbiological analyses (Legionella, pseudomonas, E. coli, enterococci), and chemical analyses covering heavy metals, nitrates, pesticides, and corrosion parameters. Sampling is carried out by DVGW-certified personnel working exclusively with accredited laboratories; the company explicitly states it will not perform sampling at sites where it has previously handled installation or disinfection, preserving a documented neutrality position that anchors its value proposition.

The customer base is B2B and regional, concentrated in Bavaria, with three primary segments: hotels and hospitality (TrinkwV-mandated Legionella testing), property management companies (regular compliance testing for residential portfolios with installations exceeding 400 liters), and homeowners (voluntary water-quality checks). Revenue is generated through professional-services fees on a quote basis per engagement, with distribution handled via direct on-site field service supplemented by phone, email, and a lightweight digital footprint (company website, Instagram, Google Reviews). Recurring demand is structurally supported by the TrinkwV requirement to test Legionella on a three-year cycle for qualifying commercial and large residential properties.

Operationally, the business is owner-operated by Aleksandar Tovarlaza and operates without external funding, parent company, or institutional ownership of any kind. Differentiation rests on DVGW and VDI 6023 staff certification, exclusive reliance on accredited laboratory partners, and an "Rundum Sorglos" (all-inclusive) service that bundles testing and remediation coordination until water meets legal thresholds. The offering has also been extended into paid Wasserhygiene Schulung (training) and Sachkundelehrgang Wasserproben (sampling certification) courses that issue DVGW-recognized certificates.
