Common Mistakes to Avoid
Implementation failures usually come from choosing a tool that does not match your primary workflow output, or from underestimating configuration and modeling effort needed to get usable analytics and evidence.
Buying a workflow tool when you actually need hydraulic modeling
If you need coupled sewer and catchment simulation with calibration for CSO and flood risk studies, Bentley StormMaster and Wallingford Hydro Science (InformationWorks ICM) are the modeling-focused options, while GIS Cloud and MASS GIS are visualization and spatial workflow tools. InfoAsset Manager and SMIS Stormwater Module provide operational tracking and reporting but they do not target engineering-grade hydraulic computation.
Skipping governance and audit requirements for evidence-based compliance
Teams that rely on inspection evidence should prioritize audit-friendly recordkeeping in OpenGov Stormwater and risk-based compliance evidence in Acuity Risk Stormwater. Teams managing asset data changes should use InfoAsset Manager because it emphasizes change control and audit trails tied to inspection and work activities.
Underplanning workflow configuration and internal ownership
OpenGov Stormwater and Acuity Risk Stormwater can require strong internal ownership because workflow configuration drives the quality of status history and advanced analytics outcomes. Cartegraph Stormwater and InfoAsset Manager also require setup complexity that can slow rollout if you do not staff data modeling and configuration.
Expecting a GIS-first publishing tool to replace stormwater analysis
GIS Cloud and MASS GIS excel at web map authoring, link-based sharing, and map-based reporting, but GIS Cloud has limited built-in stormwater modeling and MASS GIS is not a hydraulic or hydrologic modeling suite. For analysis and scenario comparisons, use Bentley StormMaster or Wallingford Hydro Science (InformationWorks ICM) instead.
