Wastewater – Hydraulic

Knowledge of the hydraulic discharge conditions in a sewer system is an important basis for many decision-making processes. Only those who have detailed knowledge of the utilisation of their sewers and structures can adapt their sewer network correctly to the continuously changing conditions. The increase in heavy rainfall events and ever stricter environmental law requirements make it necessary to find sustainable solutions for climatic, environmental and demographic developments.

To be able to respond specifically to customer requirements, we have various software programs available for hydrodynamic network calculation, such as HYSTEM EXTRAN and MIKE URBAN. Due to our comprehensive approach, large sewer networks as well as individual sub-areas can be modelled and hydrodynamically simulated.

The preparation of general drainage plans with the superimposition of the structural and hydraulic rehabilitation requirements is an essential core competence of our engineering company and of considerable importance, since the results of this basic planning influence the investment decisions for the further development of a sewer network for many years.

When carrying out pollutant load calculations, the storage capacity and discharge volumes of catchment areas and discharge structures are in the foreground. These calculations and long-term simulations are preferably carried out by STEIN engineers using the KOSIM software.

Our hydraulics experts are of course also in great demand for specific questions concerning the topic of discharge control (bypass concepts) during construction work. The dimensioning of efficient pumping systems or siphon lines is a decisive factor for the success of the project, especially in the rehabilitation of large main collectors.
