Application of the Complex Parallel Step Method for the verification of the influence of modern controlling elements in large sewage systems regarding its functionality and ecological lastingness.
In the urban drainage the requirements on the disposal of wastewater continually rise because of heavy and unsteady rainfall. Important premise for this is to estimate dirt freight discharges and floodings, which is difficult to realize.The simulation program of tandler.com from Buch am Erlbach calculates dirt freight discharges for middle and large duct systems exceedingly reliably and realistically. Therefore, discharge freights can be reduced and discharges systematically controlled. This way, the program contributes decisively to the protection of environmental and water.
A purposeful application of armatures, such as gush rinsing hatches, swinging brakes or turning bends, can reduce dirt freight discharges lastingly. Through discharge delay, sewer storage volumes can be exploited and deposits removed. The tandler.com ltd developed the so-called „Complex Parallel Step Method“, which is based on multi-core-technology. It allows a longterm and exceedingly realistic simulation of backflow afflicted and end even steered systems. The program is able to digitalize sewer networks, to graphically illustrate them and to show possible modifications.
In addition to this, data from local precipitation evaluations of many years uncover infirm points of existing sewer systems and of those to be planned. Additional modules make it possible to apply calculation methods for hydraulics, reconstruction and asset evaluation. The reliable simulation contributes to an optimization of the planning process and a minimization of the costs.
In Cooperation with the Universities of Applied Sciences Konstanz and Munich the models have been examined for their validity in the laboratory.The verification of the capability in the practice of the advanced Parallel Step Method has been rendered by a longterm simulation of the sewer network of Landshut. Further optimizing calculations showed that the application of innovative controlling elements helped to avoid congestion and achieved a considerable reduction of the emission quantities, without impairing the drainage comfort and the security of the sewer system.
The simulation with the help of the new system brings the different aspects of conduit management: regulation, purgation, use of present retention space as well as rainwater management together. The reached accelerations and decelerations of discharges can rise the functionality considerably and lead to an ecologically and economically optimized management of sewer systems in urban catchment areas.
