ENREGIS GmbH

ENREGIS GmbH is a German, owner-managed mid-sized industrial company specialising in holistic water management. Founded in 2008, it describes itself as having grown from a start-up into a "Green City family" and positions itself as a flexible, modern industrial enterprise that has repeatedly influenced the market for modern rainwater-management systems and set technology and safety benchmarks in the sector. Its product and service spectrum covers rainwater management, green infrastructure, special tanks and water-protection systems, and wastewater technology. The company's core business is the holistic, modern and sustainable management of rainwater. Under its green-infrastructure activities it qualifies tree and planting sites and carries out surface de-sealing and greening, which it presents as building blocks of its integrated "sponge city" (Schwammstadt) concept for climate-resilient urban development. It also supplies special containers and water-protection installations — individual project solutions for customer- and country-specific requirements in weight-optimised designs that simplify transport logistics — as well as wastewater technology for the reliable treatment of wastewater of all kinds before discharge into the environment. ENREGIS has expanded beyond a pure product offering into a broad service portfolio, from project-specific design through to the installation of complex system structures as a partner for its customers in civil engineering. From 2017 the rainwater-management business area was complemented by a portfolio in the green-infrastructure segment, and activities in the Alpine region were expanded. The company works with strong partnerships in research and the regional economy, and increasingly places the theme of climate at the centre of its entrepreneurial activity, arguing that mitigating the dangerous consequences of climate change in urban areas begins with the sustainable handling of the resource of precipitation water. ENREGIS is headquartered in Germany and operates primarily in German-speaking markets, including Germany and Austria and the wider Alpine region. It is an owner-managed private company rather than a listed corporation. Its product range includes filter substrates and compact treatment systems, such as the ENREGIS/Biocalith MR-F2 "CS" filter substrate tested to ÖNORM for a 1:100 area ratio, and the ENREGIS/Vivo Treat MR-F4 compact system for treating organic and inorganic loads, aligned with the high requirements of German guidelines and standards. In 2026 the company announced a merger with the ACO Group, a significant development for the business.

ENREGIS GmbH was founded in 2008 and describes itself as having developed from a start-up into a "Green City family". From the outset it operated as a flexible, owner-managed and modern mid-sized industrial company, and it states that it has repeatedly influenced the market for modern rainwater-management systems and set important benchmarks in the industry, creating new technology and, above all, safety standards. The company's origins lie in water management, with a long-standing professional background in holistic, modern and above all sustainable rainwater management. Over time, the further development and international orientation of the business led to an increasingly holistic view of water treatment, supply and disposal, and to the development of cross-cutting concepts and holistic solution approaches for the challenges of customers and the markets of tomorrow. These deliberately go beyond a pure product offering and include an extensive service portfolio, from project-specific design through to the installation of complex system structures as a partner for customers in civil engineering. A key turning point came in 2017, when the rainwater-management business area was complemented by a portfolio in the green-infrastructure segment and activities in the Alpine region were expanded. Green infrastructure — the qualification of tree and planting sites as well as surface de-sealing and greening — became an important building block of the company's holistic ENREGIS sponge-city concept for climate-resilient urban development. Coming from the field of water management, the company increasingly oriented itself to the climatic challenges of the present and developed solutions that clearly go beyond its original horizon, placing the theme of climate at the centre of its entrepreneurial activity. Alongside rainwater management and green infrastructure, ENREGIS built out further business areas: special tanks and water-protection installations, offering individual project solutions for special, customer- and country-specific requirements in weight-optimised designs that enable straightforward transport logistics; and wastewater technology, which the company regards as one of the most important building blocks of holistic water management because of the need for reliable treatment of wastewater of all kinds before it is discharged into the environment. The company has relied on strong partnerships with competencies in research and the regional economy. Its product development has produced items such as the ENREGIS/Biocalith MR-F2 "CS" filter substrate, tested to ÖNORM for a 1:100 area ratio and intended for compact systems and line drainage channels with integrated precipitation-water treatment technology, and the ENREGIS/Vivo Treat MR-F4 compact system for treating organic and inorganic loads, aligned with the high requirements of German guidelines and standards. In 2026 ENREGIS announced a merger with the ACO Group, a major step in the company's development.
