About INOWA

INOWA Abwassertechnologie GmbH was founded in 1992 in Marchtrenk (Upper Austria) and has established itself as a specialist in wastewater technology. The company develops and manufactures maintenance-free, filterless oil separators, oval tank systems, fully biological wash water treatment plants and fully automatic wash water filtration systems. The portfolio is complemented by warning and monitoring systems for separators with oil layer thickness measurement, level and inlet valve monitoring. The tank systems are made of concrete with concrete covers, and the interior lining is made of PEHD (high-density polyethylene). INOWA sees itself not as a supplier of mass-produced goods, but as a partner for individual solutions tailored to customer requirements – from research and development to consulting, planning and project management through to sales, delivery and customer service. Thousands of separator systems and numerous wash water treatment plants have been installed in Austria, Europe and worldwide, including for airports, the automotive industry, mineral oil trading and car wash operations. In addition to its headquarters with production in Marchtrenk, the company includes a concrete tank production facility in St. Valentin, a service branch in Korschenbroich (Germany) and a representative office in Switzerland.
