ADS Environmental Services has been developing this software tool over a 12-year period as an in-house utility to speed up the process of dry and wet weather analysis for I/I studies. The online software is now available to users who acquire sufficient training. Beta testing by engineers in 2004 indicated that time required for I/I analysis using this tool can be from 1/6th to 1/10th the time required by spreadsheet-based tools. Additionally, the software performs an array of engineering functions to provide a full understanding of the system performance. These include: Rainfall Analysis, Dry Day Analysis, Scattergraph Analysis, Storm-by-Storm I/I Calculation, Depth-Duration-Frequency of each storm, Q-to i Relationships and Pre- and Post-Rehabilitation Analysis.
Most engineers have a preferred method for how data are parsed and analyzed and spreadsheetbased tools make it difficult to modify the type of analysis performed. Sliicer presents the engineer with over 30 separate settings or controls that allow the analysis to answer different questions and solve different problems. The entire analysis can be re-done in minutes to allow rapid “what-if” questions to be answered.
