Common Mistakes to Avoid

Common failure modes come from choosing a tool whose modeling scope does not match the project’s main drivers or whose workflow depth becomes burdensome for the design scale.

  • Choosing a network-only model for treatment train process sizing

    eWater/EPANET Studio focuses on EPANET-based hydraulics and water quality network simulation and has limited wastewater treatment process design capabilities compared with plant-focused tools. SYSTEA and Canalix are built around treatment train workflow outputs and reduce rework when treatment process sizing is the primary task.

  • Overbuilding for small projects using a heavy integrated environment

    Bentley OpenFlows CONNECT Edition can feel heavy for smaller projects with limited scope because workflow setup can be substantial and large models can slow without careful data management. SYSTEA or Canalix can fit teams when the goal is structured calculations and report-ready outputs without requiring a broad CONNECT-driven shared data environment.

  • Underestimating input data preparation and QA requirements for simulation tools

    MIKE URBAN and MIKE by DHI require careful data preparation for accurate network and catchment inputs because hydraulic and water-quality simulation depends on disciplined model setup. eWater/EPANET Studio also requires direct alignment with EPANET structures so assumptions and network objects must map cleanly to achieve usable results.

  • Treating civil geometry software as a substitute for treatment performance modeling

    Autodesk Civil 3D excels at corridor modeling from alignments and profiles for grading and conveyance geometry and it does not function as a full process design platform for treatment trains.
