Deteriorated wastewater lines have the potential to leak wastewater into the groundwater systems, resulting in groundwater contamination and environmental fines. These result in expensive remediation that can be avoided if the deterioration can be identified and mitigated early.

The tool allows municipal utilities to identify deteriorated wastewater infrastructure. It is used by engineers to analyze the spatial relationships of wastewater flow, hydrologic, and weather information. The tool analyzes wastewater transport in a combined open- and closed-system in order to identify line segments that receive input from external sources, which indicates the presence of breaks and cracks. Municipal utilities then use this information to more efficiently maintain their wastewater infrastructure, save time, and avoid regulatory fines.

Wastewater DSS uses the rainfall and snowmelt data to calculate input from human and atmospheric sources. If the calculated infiltration/inflow amounts are above a certain level then pipeline deterioration is probable for a pipe segment of interest.

Dashboard Visualizationpg_wastewater

The tool uses technology from Dundas Data Visualization, Inc. to create dashboard data displays to track flow rates, weather, and hydrologic conditions in areas of interest. The charts can be exported to industry-standard formats such as Adobe PDF for distribution to other managers and engineers in an organization.

Spatial Visualization

Wastewater DSS uses relational database management systems to store and manage wastewater data. The tool loads field data into an ArcGIS geodatabase for geoprocessing, data validation, and display. The data are then plotted using the ArcGIS Spatial Analyst® extension from ESRI.

The tool allows users to visualize the spatial relationships between the wastewater infrastructure, data collection points, land use and zoning, topography, and other geographic features in one integrated application. Data in Wastewater DSS can be output to any file format supported by ArcGIS, including AutoCAD® and MicroStation®.

Mapping functionality built into the tool provides users with a true geospatial decision support system. It provides built-in value for public works departments and engineering firms. It is a tool that saves organizations time and money as they attempt to maintain aging wastewater infrastructure.
