| Dynamic Design Storm | VIEW DEMO |
Ultimately, the whole purpose of creating a sewer model is to find out how your system will react under various circumstances, and often, actual or synthetic storm events are used as design criteria. Certainly in combined storm and sanitary sewer systems, it's important to consider the timing of storm events in relation to the sanitary patterns. Most existing sanitary sewer systems have enough infiltration and inflow that the system behaves as though it were a combined storm and sanitary system. Planning For The Worst Case Scenario For any given design storm, the resulting total peak flow could vary wildly - depending on the timing in relation to the sanitary flows. For any large collection system, even the best attempt to manually adjust the storm to coincide with peak sanitary flows is not sufficient, because the peak times will vary throughout the system. Dynamic Modeling HYDRA® software has a unique ability to dynamically adjust the timing of the start of the storm to find the maximum peak flows for your design storm. For each pipe in the system, it shifts the peak of the stormwater to coincide with the peak of the sanitary flows.
