CCTV (Closed-Circuit Television )
Inspection and Condition Assessment - Before
• Multiple Contractors for different time periods.
• Different rating systems
• Different reporting systems
• Lack of access for District staff - video files were stored at district server
• Lack of QAQC

GIS data as the foundation
• District CCTV van with computer equipment and CCTV camera
• Unique ID was assigned to each pipe segment in GIS
• ArcReader application and CCTV interface /data management software (POSM) were installed in the van’s computer
• GIS data was exported as the foundation to inspect the pipes
![Page 10: Integrate CCTV Data to Enterprise GIS Work Flows - Esriproceedings.esri.com/library/userconf/water15/papers/water_13.pdf · Introduction •Background of Otay Water District •GIS](https://reader031.vdocuments.site/reader031/viewer/2022011723/5aa41e2e7f8b9ae7438b95d2/html5/thumbnails/10.jpg)
Operation to collect the inspection data
• Locate the pipe through ArcReader
• Prepopulate pipe information from GIS automatically
• Enter the inspection info into POSM
• POSM controls the CCTV camera
• Observations are entered
• PACP and MACP codes are automatically populated

Synch field data to GIS server
• Schedule the CCTV van to connect to network
• Synchronize the newly collected records into server database
• Maintain the database in the van periodically.

POSM server based database
• SQL server based
• Use FacilityID as the unique key
• Create a unique URL for inspection report for each segment
• Adopt the NASSCO rating standard
![Page 15: Integrate CCTV Data to Enterprise GIS Work Flows - Esriproceedings.esri.com/library/userconf/water15/papers/water_13.pdf · Introduction •Background of Otay Water District •GIS](https://reader031.vdocuments.site/reader031/viewer/2022011723/5aa41e2e7f8b9ae7438b95d2/html5/thumbnails/15.jpg)
NASSCO standard for sewer system
• NASSCO - National Association of Sewer Service Companies
• Adopt the NAASSO Standard across the board
• Operation
• Engineering
• Asset Management program
• Promote Training and Certification Program in the District
• Pipeline Assessment and Certification Program (PACP)
• Manhole Assessment and Certification Program (MACP)
• Lateral Assessment and Certification Program (LACP)

Operation preventive maintenance
• Schedule the cleanup using the condition score
• Target more on the known area for high frequent maintenance
• Notify the property owner for lateral cleanup
• Develop a rehabilitation and replacement plan based on the inspection data
• Budget the replacement based on the condition score

Engineering Capital Improvement Plan
• Access the CCTV data through GIS viewers
• Access the observation report through GIS viewers
• Produce critical pipe segment report
• Asset Management Program
