TV INSPECTION OF SEWER LINES

11/21

NOTE: This guide specification covers the requirements for pipeline cleaning and TV inspection of sanitary or storm sewer pipelines. Use tailoring options SANITARY or HERBICIDE to select the appropriate system for the project.

Adhere to UFC 1-300-02 Unified Facilities Guide Specifications (UFGS) Format Standard when editing this guide specification or preparing new project specification sections. Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable item(s) or insert appropriate information.

Remove information and requirements not required in respective project, whether or not brackets are present.

Comments, suggestions and recommended changes for this guide specification are welcome and should be submitted as a Criteria Change Request (CCR).

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 4

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.

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

NOTE: This paragraph is tailored for SANITARY.

Minimize the interruptions to the existing flows to perform the cleaning

SECTION 33 01 30.16 Page 15 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 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.

[3.1.4 Manhole or Structure Cleaning

NOTE: Indicate on drawings manholes or structures to be cleaned.

Clean concrete and masonry surfaces prior to CCTV inspection. Completely remove grease, laitance, loose bricks, mortar, unsound concrete, loose or damaged wall mounted steps (cut flush with wall), and other materials.

It is acceptable to use other methods of cleaning such as concrete cleaners, degreasers or mechanical means to clean the surfaces. Thoroughly rinse, scrub, and neutralize the surfaces in order to remove cleaning agents and their reactant products. Do not allow material to pass to pipeline sections, which could adversely affect water quality, cause stoppages, accumulations of sand in wet wells, or damage to pumping equipment.

]3.1.5 Flow Control

Reduce the flow depth to allow a minimum of 80 percent of the pipe wall to be displayed at all times during inspection so that defects, features, and other notable information can be collected.

3.1.5.1 Flow Reduction

Flow depth reduction can be accomplished by:

a. Providing bypass pumping.

b. High-pressure jet nozzle.

c. Plugging or by pulling the camera with a swab.

d. Performing the CCTV inspection during periods of minimal flow.

3.1.5.2 Floating the Camera
