Anyone who provides water to the public bears a public responsibility. This responsibility extends from the water utility’s elevated storage tank to the sink in the daycare center. We support municipalities, municipal utilities, and institutions in meeting all obligations under the Drinking Water Ordinance and DVGW regulations: cleaning, disinfection, sampling, and the documentation required by public health departments.
Railway tenders, procurement processes, framework agreements: We have been working with the public sector for over 30 years, from the German Armed Forces to local governments. You’ll receive reliable quotes with a detailed breakdown of costs, on-time execution in accordance with ISO 9001, and documentation that stands up to any audit. We also keep statutory reporting and documentation requirements in mind throughout the process.
