itwh has been working in the fields of urban drainage engineering and stormwater management for nearly 20 years. Our main fields of activity are:
- Consulting services/Engineering projects
- Software development
- Software training courses
.
Consulting services/Engineering projects:
Our consultants are assisting drainage engineers and local authorities in the fields of stormwater management and the planning and optimization of urban drainage systems. We always find and apply innovative technologies, and try to develop sustainable solutions that have to be practically, ecologically, and economically sensible. Our engineering projects comprise...:

Software development:
The two fields of activity "Consulting services" and "Software development" are interlinked on purpose. It is important to be competent in a particular area, i.e. in project engineering, to be able to develop optimal and state-of-the-art application software. This is the reason why we are only developing software programs for areas in which we have extensive engineering experience. Our main software products are...:
- HYSTEM-EXTRAN (urban sewer systems simulation, hydrodynamic transport calculations; with integrated database)
- GIPS (visualization and modeling of urban sewer systems from within AutoCAD; uses the HYSTEM-EXTRAN database)
- KOSIM (analysis of retention basins in urban drainage systems (such as combined sewer overflows, trough and trench systems, stormwater retention ponds), continuous simulations meant to assess a system's performance)
- CONTROL (Quantity- and quality-oriented Real-Time-Control of sewer systems, uses HYSTEM-EXTRAN as simulation model)
Several small applications and add-ons are available for special tasks.

Software training courses:
Training courses play another important part in itwh's activities. itwh consultants have many years of experience and always had a close relationship to the universities. Thus, we are able to present, during our training courses, a specific software package to our customers, and - what is even more important - to introduce these customers to new industry standards and to give them practical and scientific background information.
