ISA - Institut für Siedlungswasserwirtschaft der RWTH Aachen University

What ISA - Institut für Siedlungswasserwirtschaft der RWTH Aachen University does

ISA - Institut für Siedlungswasserwirtschaft is a university research institute within RWTH Aachen University's Faculty of Civil Engineering, founded in 1966 and celebrating its 60th anniversary in 2026. The institute conducts basic and applied research across the urban water cycle, with dedicated research areas in wastewater treatment (biological, membrane, advanced oxidation), particulate pollutants, resource management (notably phosphorus recovery), urban drainage and stormwater systems, drinking water and water reuse, and environmental analytics including trace-substance detection and wastewater-based epidemiology. Operations are supported by a headquarters on the RWTH campus (Mies-van-der-Rohe-Str. 1) and the μ3 Research Center Soers co-located with the Aachen-Soers wastewater treatment plant (Krefelder Str. 299), the latter providing pilot-scale and laboratory infrastructure.

The institute's service portfolio is academic rather than commercial: it delivers bachelor's, master's, and doctoral teaching programs in environmental engineering, publishes peer-reviewed research and technical series (GWA, ARA, ATW, ASS), organizes recurring industry events (the Cologne Canal and Wastewater Treatment Colloquium, the Aachener Tagung Wassertechnologie), and executes funded research projects. Funding flows from RWTH institutional support, competitive public grants (BMBF, state ministries such as NRW's LANUK, EU programs), and project-based industry co-funding from water utilities (Erftverband, Abwasserverband Braunschweig, Wasserverband Eifel-Rur) and water-technology companies (Xylem, inge, Analytik Jena, Autarcon, PEGASYS). There are no commercial products or services; the affiliated Gesellschaft zur Förderung des Instituts and FiW research institute operate as nonprofit partners supporting publications, events, and applied research.

Strategically, ISA functions as a standards-influencing knowledge hub for German and European urban water management, with active roles in DWA technical standards, DIN bromate-determination methodology, and multi-institution projects such as FlexTreat, ValidReuse, and EPHIC. Its competitive position rests on six decades of domain specialization, talent pipelines through RWTH Aachen, regulatory engagement, and a dense partner network spanning utilities, industry, and European academic institutions, rather than on proprietary commercial technology.
