About ENREGIS
Founded in 2008, ENREGIS GmbH is an owner-managed medium-sized industrial company headquartered in Sundern (Sauerland) with a location in Austria (ENREGIS Österreich GmbH, Hall near Innsbruck). The company manufactures and distributes systems and plants for stormwater management, water protection, wastewater technology, and spring and drinking water supply. The portfolio includes retention systems (ENREGIS/X-Box), treatment plants such as lamella clarifiers and adsorption filters, concrete slot channels, mineral high-performance filter substrates (Biocalith, produced via DISPOplus), and drinking water tanks and systems made from food-grade HDPE with drinking water approval, from stainless steel, or as a material symbiosis – in compact design up to 70 m³ or as modular systems with diameters of 1000 to 3000 mm. Frames, holding structures, and support elements are manufactured project-specifically from stainless steel or GRP. In addition, ENREGIS offers project-specific design and hydraulic calculation, installation of complex system structures in civil engineering, monitoring and control technology (SmartWater Protect), as well as maintenance and filter replacement. Customers come from civil engineering, sports facility construction, the food and chemical/pharmaceutical industries, logistics, municipalities, and transport routes; references include, among others, the Olympiastadion Berlin, the BMW plant Regensburg, and REMONDIS.

Quality and Certification
The quality of the filter and drinking water systems is demonstrated by independent certifications: the Biocalith filter substrates MR-F2, MR-F2 ECO, and MR-F3 are ÖNORM-tested, and the ENREGIS/Pure drinking water systems are optionally ÖVGW-certified. In-house tests (e.g., IRO flushing strength per DIN 19523, reports from MFPA Leipzig) supplement the system testing.
