CCTV Inspection for Sewer and Drain Main Lines (Item 15-27)
The Contractor shall furnish all labor, tools, equipment, materials, and supplies required for CCTV
inspection of sewer, drain, and catch basin lateral pipes as requested by the City, including in areas
located within the City’s easements on private property.
Plans shall be provided by the City showing streets and pipes where services are needed. Plans will not
show all catch basin lateral pipes or structures.
Pipes types to be videoed include: sewer pipes, drain pipes, and catch basin lateral pipes. Pipe material,
length, and diameter are provided where information is known from City records. Sewer and drain pipe
video is required 30’ into connecting streets. Video shall extend to the first manhole of the connector
Street. If the first manhole is less than 30’ into the connecting street, video shall extend to the next
manhole in that street.
Laterals of catch basins shall be videoed even when they extend more than 30’ into connecting streets.
In all situations, lateral videos shall be from the catch basin to structure or main line pipe.
In the event CCTV inspection cannot be performed by the contactor due to major debris accumulation
and/or blockage, the contractor will clean the lines again then continue with the inspection. In addition,
should upstream flows need to be stopped for inspection purposes; the cantractor will notify the City
prior to the placement of any flow stopping devices. The CCTV of this reach may need to be re-
scheduled depending on the availability of a city crew. If a surcharge occurs, due toa blockage caused by
the Contractor, the Contractor at his own expense shall repair it.
The camera shall be moved through the line in either direction at a uniform rate, stopping when
necessary to ensure proper documentation of the sewer’s condition. In no case shall the television
camera be pulled at a speed greater than thirty feet per minute (30 fpm).
As the camera approaches a lateral connection or defect, the camera progress shall be halted and the
camera lens panned to further view the lateral pipe and connection {including looking up the lateral} or
defect to thoroughly evaluate the condition.
