Common Mistakes to Avoid
Wastewater modeling failures usually come from workflow misfit, calibration readiness issues, or outputs that do not align with decision deliverables.
Choosing a tool without matching it to the modeling scope
Teams that require activated sludge biological kinetics outcomes should not default to hydraulic-only workflows and should instead use BioWin or OpenModelica for equation-based process simulations. Teams focused on GIS-linked sewer hydraulics and scenario comparisons should prioritize InfoWorks ICM or InfoWorks CS instead of tools that emphasize non-GIS workflows.
Running repeated alternatives without formal scenario management and auditing
In complex wastewater networks, hidden data and connectivity issues create misleading comparisons when runs are not organized by scenario and validation. InfoWorks CS and InfoWorks ICM provide scenario management with GIS-based model auditing and model validation checks to reduce silent errors.
Underestimating calibration and setup requirements for stable model credibility
Complex setups can demand specialist knowledge for stable and credible calibration in InfoWorks ICM, and advanced workflows in InfoWorks CS require configuration and QA discipline. Calibration-focused studies should use ASCE-MOPID when structured parameter estimation matters, while dynamic bioreactor customization should use OpenModelica only when Modelica debugging and solver tuning capacity exists.
Expecting complex output tailoring without planning for reporting effort
Results customization can take effort for highly tailored reporting formats in InfoWorks CS, and manual tuning may be required for BioWin reporting outputs in typical study deliverables. Teams with strict reporting templates should allocate time to validate visualization and reporting workflow fit in InfoWorks ICM, AQUA, and OpenFlows Sewer Modeling before model build-out.
