Institute for Technical and Scientific Hydrology (Germany)

The Institute for Technical and Scientific Hydrology (itwh GmbH) is a German planning, consulting and software company based in Dresden. It works at the interface between engineering practice and hydrological science, focusing on the practical fields of hydrology: water-resources management and hydraulic engineering. As an independent planning and consulting firm, itwh relies on a committed team with high competence in civil engineering, hydrology and information technology. Alongside consultancy, itwh develops software solutions for drainage, hydrology and water-resources management. Its programs support planning, analysis and simulation, and are described by the company as practice-oriented, scientifically grounded and user-friendly. The portfolio spans both desktop applications and web-based solutions, providing tools for efficient and safe working processes. A third pillar of the business is knowledge transfer between research and application and the further development of innovative approaches. In cooperation with various universities and research institutions, itwh advances innovation through projects and software products. The company's product family includes well-known tools in the German-speaking water sector such as HYSTEM-EXTRAN for hydrodynamic sewer and urban drainage modelling, GIPS and GIPS-Light for sewer-network data management, KOSIM for rainfall-runoff simulation, FOG Pro for general drainage planning, and RW-Tools.xlsx for rainfall data handling. itwh also operates a rainfall data portal (Regendatenportal) and offers training courses and course registration, reflecting its role as a knowledge provider for municipalities, engineering offices and utilities. itwh is a privately held company (GmbH) and is not listed on a stock exchange. Its customer base is primarily in Germany and the wider German-speaking market, where its software is used by engineering consultancies, municipal drainage operators and water authorities. The company continues to release regular updates and new versions of its core products, indicating an active development roadmap.

The Institute for Technical and Scientific Hydrology (itwh) is a German company based in Dresden, operating at the intersection of hydrological science, civil engineering and information technology. Public records describe it simply as a company in Dresden, Germany, and its own communications present it as an independent planning and consulting firm. From its base in Dresden, itwh built its business around three connected activities. The first is consulting and planning in the practical fields of hydrology, specifically water-resources management and hydraulic engineering. The second is software development: the company creates tools for drainage, hydrology and water-resources management that support planning, analysis and simulation, offered both as desktop applications and as web-based solutions. The third is knowledge transfer between research and application, carried out in cooperation with universities and research institutions and aimed at developing innovative solutions that feed into projects and software products. Over time, itwh's software portfolio has become well established in the German-speaking water sector. Its product family includes HYSTEM-EXTRAN for hydrodynamic sewer and urban drainage modelling, GIPS and GIPS-Light for sewer-network data management, KOSIM for rainfall-runoff simulation, FOG Pro for drainage planning, and RW-Tools.xlsx for rainfall data work. The company also runs a rainfall data portal (Regendatenportal) and offers training courses with online registration, reinforcing its role as a knowledge provider as well as a technology vendor. The company maintains an active release cycle. Recent announcements on its website include new releases of GIPS and GIPS-Light (Version 8.9.1), FOG Pro (Version 1.9.1) and HYSTEM-EXTRAN (Version 8.9.1), along with patches for FOG Pro, HYSTEM-EXTRAN, GIPS/GIPS-Light and KOSIM, and a new version of RW-Tools.xlsx. This cadence of updates indicates ongoing investment in product development and support for a customer base of municipalities, engineering offices and water utilities. itwh is a privately held company (GmbH) and is not listed on a stock exchange. Its market focus is Germany and the wider German-speaking region, where its software and consulting services are used in urban drainage, flood and rainfall analysis, and water-resources planning.
