GIS, Mapping, & Aerial Imagery
Managing a sewer system can be a complex, daunting task. Accurate, up-to-date records make proper maintenance and cleaning possible for the best performance of your system.
CES possesses the capability to build maps from scratch – or to update the existing maps throughout the course of our investigative study. With a combination of inspection methods, CES can create the key to managing your sewerage system–a multi-layer, comprehensive map that includes service recommendations, status updates and other analyses. See an example here:
GPS data collection provides key information for use during manhole inspections. The data collected reveals general inventory information for manholes in the system.
GIS has become the standard of the industry for managing sewer and water systems. CES can take GPS readings at sub-meter, decimeter, and centimeter accuracy levels for manholes or other points identified while inspecting a sewer system. This data can then be integrated with inspection data to create maps. For a municipality that has not yet utilized GIS technology to map and manage its sanitary sewer system, this added value offers them a chance to begin to take advantage of this technology. For clients with existing GIS systems, we can deliver the data in the way that best fits their needs. Our capabilities include:
- GPS data collection for many different municipal assets including:
- Creating new GIS geodatabases on which a municipality can begin to build a GIS system
- Creating layers for sewer asset locations
- Creating layers for CCTV inspection data and/or tracking
- Creating layers for manhole inspection data
- Creating layers for smoke test inspection data
- Creating layers to assist in prioritizing areas for services based on I/I data collected during flow monitoring
- Creating layers for rehabilitation recommendations to assist in prioritizing rehabilitation efforts by integrating inspection data with GIS
- Delivering shapefiles of the locations of the manholes as a separate dataset from the manhole inspection data, to be combined with an existing GIS dataset
- Updating and correct existing GIS data
- Creating accurate maps by integrating data with existing as-builts, delivered in PDF format
