  6. If the application is denied you will be told why and how to re-apply.

Submit a copy of the DVD to the Sewer Division. DVD Video must be done using a self-leveling camera, include footage counter, and the image quality must be clear. Failure to have the Sewer Inspector present during the TVing will result in the Sewer Division not accepting the DVD. Note: VHS format and flashdrives are not accepted. Only DVDs are accepted.
