In order to avoid sanitation problems or flooding damage, a wastewater network needs to be regularly inspected and, when necessary, renovated. To gauge the severity of necessary repairs and closely estimate renovation costs of damaged features, it is important to have accurate inspection data. This is done by means of importing inspection data.
Once you import inspection information, you can perform any of the following tasks:
- Verification of wastewater inspection data.
- Classify any damage and wastewater network features.
- Import hydraulic computation results.
Process for Importing Inspection Data
When you import inspection data, several processes take place before the imported content is fully integrated with your main industry model.
| Process | Description |
|---|---|
|
Import |
Inspection data is imported to a temporary data cache in the form of an intermediate industry model. The validity of the inspection file is also checked for inconsistencies. |
|
Feature Matching |
Feature matching occurs between the inspection data and GIS features of the wastewater network. If certain parameters coincide between an inspected object and a GIS feature (for example, section: NAME_NUMBER) a match is found. If no match is automatically found, you can select a matching feature. |
|
Attribute Matching |
When a conflict between an inspection feature and its GIS feature is detected, the inspection feature is considered a conflict feature. For example, a difference in section diameters between the inspection data and its comparable GIS feature. Conflicts do not need to be resolved when they are encountered during import. You have the option to ignore conflicts and address them after the import is complete. Conflict data is stored in a report which can be opened from the Inspection Manager. Note: The report file (WW Conflict Report.XML) has to be loaded in the Administrator and is available under the report folder of the WasteWater template.

|
Data Validation |
Data Validation checks the imported inspection data against the specified classification model. For example, section damage is checked if all necessary data is provided and only if section main codes are used. You can flag invalid features to be ignored. That means that an invalid feature would not prevent the rest of valid data from being imported. |
|
Geometry Creation |
During the geometry creation process, geometry for each damage observation in the inspection data is created. |
|
Commit Data |
All revised data is copied from the intermediate industry model to the main industry model. This process also copies any video and photo files to the server. |
Prepare to import inspection data
Before you can import any inspection data, you must have a wastewater project that contains two wastewater industry models; the main industry model and an intermediate industry model.
The main industry model conatins the Wastewater Data Model module and your wastewater project data. The intermediate industry model is created using the Wastewater Data Model (for Intermediate Industry Model) module, and is used to temporarily store the imported data.
