PART 1 GENERAL

NOTE: TV inspection of sewer pipelines is commonly referred to as closed circuit television inspection

(CCTV). CCTV inspection is used to determine the condition of existing pipelines and to identify lateral connections prior to slip lining. It is also used to verify relining of existing piping conforms to project specifications, warranty requirements and to confirm lateral re-connections post-construction. CCTV inspections indicate the location of service connections along the main and the location of pipe conditions warranting further action.

SECTION 33 01 30.16 Page 5

Cleaning or heavy cleaning is always performed prior to CCTV inspection.

Point repairs may also be required prior to Pre-TV inspection; requirements for point repairs are not addressed in this section. Point repairs are typically less than 3.0 meters 10 feet in length.

Prior to conducting a Pre-TV inspection the engineer should conduct a field investigation to determine pipelines or sections of pipes requiring heavy cleaning and the potential for point repairs.

Pre-TV inspections of mains and laterals are needed to assess existing conditions, confirm point repairs and assist in preparing project specifications for

33 01 30.72 RELINING SEWERS and may be done during field investigation. Once the contract is awarded, the contractor will need to do a second PRE-TV inspection before beginning slip lining work.

Post-TV and Warranty TV inspection portions of these specifications are needed to confirm work performed for slip lining sanitary sewer and storm drainage systems conforms to the project specifications.

3.1.3 Sewer Line Cleaning

NOTE: Indicate on the drawings the pipe segments requiring heavy cleaning. Heavy cleaning may not be required if the field investigation cleaning and

Pre-TV inspection were recently completed. Heavy cleaning may be needed for small diameter pipes in areas known to have frequent maintenance cleaning due to heavy grease or root intrusion. Larger diameter pipes (equal to or greater than 18 inches) will typically not require heavy cleaning unless previous problems have been observed or are known.

This should be easily discernible when conducting field investigations.

Immediately prior to conducting CCTV activities, thoroughly clean the segment of sewer pipe to be video inspected. Clean the segments using hydraulically propelled, high-velocity jet, or mechanically powered equipment.

a. During cleaning and preparation operations, undertake precautions to protect the sewer system and property from damage. Restore property damaged as a result of such cleaning and preparation operations to pre-existing conditions.

b. During the course of normal cleaning operations immediately report pre-existing damage such as broken or missing pipe to the Contracting

Officer.

c. When hydraulically propelled cleaning tools or tools which retard the flow in the sewer line are utilized, take precautions to ensure that the water pressure created does not damage or cause flooding on the adjacent site.

d. Maintain access to fire hydrants for the purpose of fire protection at all times.

e. If cleaning of an entire sewer section cannot be successfully performed from one manhole or structure, set up the equipment on the other entry or exit point and attempt cleaning again.

f. If successful cleaning cannot be performed from the opposite end or the equipment fails to traverse the entire pipeline section, cease cleaning those specific sewer sections, notify the Contracting Officer and CCTV inspect both sides of the pipeline section to determine the cause of the blockage.

3.1.3.1 Sanitary Sewer Cleaning

Minimize the interruptions to the existing flows to perform the cleaning of the sewers. Prevent sewage backups and immediately clear back-ups resulting from the cleaning operations. When possible, utilize the flow in the sewer system to provide the necessary pressure for the hydraulic

SECTION 33 01 30.16 Page 15 cleaning devices. Return sewage diverted during cleaning operations to the sanitary system and do not discharge onto any surface, or into any water body or storm drain system.

3.1.6 Root Removal

NOTE: The existence of roots indicate pipe fractures, joint openings or other failures.

Typical root removal is performed by use of cutting heads. Extreme conditions require the use of chemical root treatment in order to obtain clear, unobstructed video images.

Use the CCTV field investigation report to determine sections of pipe containing roots. Indicate on

SECTION 33 01 30.16 Page 16 drawings sections of pipe, manholes or structures requiring root removal.

Remove roots in the designated sewer sections[ and manholes or structures]. Ensure complete removal of roots to the joints. Use mechanical equipment that can be operated remotely, such as rodding machines, bucket machines, winches using root cutters and porcupines, and equipment such as high-velocity jet cleaners. Capture and remove roots from the sewerline at the downstream manhole or structure.

3.1.7 Material Removal and Disposal
