Storage Maximum Outflow Includes the Reverse Flow in SWMM 5

Note:  Storage Maximum Outflow Includes Reverse Flow in SWMM 5

 

The SWMM 5 text output file has a Storage Volume Summary Table.  The Maximum Outflow from a storage node includes ALL of the outflow from the Storage node including both downstream link flow and reverse flow into the upstream links of the storage node.  You need to look at all of the flow out of a Storage node to find out how the maximum flow was computed during the simulation.

InfoSewer is used worldwide by municipal engineers

InfoSewer is used worldwide by municipal engineers and planners to create detailed, accurate models of their sewer infrastructure systems. These models enable users to evaluate the effect of new developments, zoning changes, and other additional loads on system flows; pinpoint current and future problem areas; predict overflows and backups; and determine how to best restore needed capacity lost to infiltration and inflow with the least rehabilitation. In addition, users rely on these models to compute hydrogen sulfide generation and corrosion potential; analyze the rate of Biochemical Oxygen Demand (BOD) exertion; track sediment movement and deposition; trace pollutant contribution from source nodes, perform time of concentration pipe calculations, calculate the amount of pollutant transported to the wastewater treatment plant; and assess pollutants’ impacts on receiving waters. Extensive scenario management functionality makes the program capable of analyzing existing or future sewage collection systems. The application also provides vital tools for meeting and exceeding environmental regulations and improving community relations via database queries and map displays.
