Regional Infiltration and Inflow Control Program

TV Inspection

TV Inspection: Recording conditions using a TV camera within the pipes. Closed Circuit TV (CCTV) cameras have been developed that can be slid down sanitary sewer lines and record a "movie picture" of the conditions that are found in that section of sewer. This can identify breaks, root intrusion, leaking water (especially infiltration from groundwater), and general deteriorating conditions. Estimates can be made for how much infiltration might occur from such leaks.
