Intoduction: 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; calculate the amount of pollutant transported to the wastewater treatment plant; and assess pollutants’ impacts on receiving waters. Extensive scenario management along with domain and facility management functionality makes the program capable of analyzing existing or proposed sewage collection systems. It has a Steady State, Design and EPS run modes and includes many of the same Arc Map tools that exist in InfoWater and InfoSWMM.
This is how InfoSewer can use a time series of inflow at a specific node:
1. Use a mean loading of 1 so that the values in the Inflow Time Series stay the same as your inflow units in InfoSewer (Figure 1)
2. Create a PATTERN that is equal to your inflow time series
3. The pattern has to have the same time steps as your default Run Manager Pattern option, normally this will be one hour
4. The factor column is your inflow in cfs, gpm, lps or mgd (Figure 2)
5. The Base Load should equal your Inflow Pattern (Figure 3)
