Start with the segment list: confirm that the drawings identify every main and service to be cleaned and inspected by the manhole or structure IDs at each end, the IDs the video overlay and the logs will carry, and that they mark the segments needing heavy cleaning, the manholes or structures to be cleaned, and the sections needing root removal, as the three drawing notes of the issued Section 33 01 30.16 ask. Then check that the inspection phases kept, Pre-TV, Post-TV, Warranty-TV, and Re-TV, match the relining or new-pipe sections that call them, that bypass pumping, traffic control, disposal, and any herbicide treatment are actually specified for the site, and that the video, log, and defect coding deliverables are ones the owner can accept.
Assemble the review package
Gather the sewer rehabilitation or utility plans with every main, service, manhole, and structure ID, the segment schedule if there is one, the engineer’s field investigation report and any earlier CCTV video and logs, the point repair and relining drawings, the bypass pumping and flow control plan, the traffic control drawings for manholes in or beside roads, the site plan with hydrants, water sources, staging, and disposal sites, the wastewater treatment plant and installation pest management contacts where herbicide is used, the owner’s requirements for video media, file formats, and PACP coding, and the issued Section 33 01 30.16 with Section 33 01 30.72, Section 33 40 00 or 33 30 00 where new pipe is inspected, and Section 01 33 00. Follow one segment from its entry manhole to its exit manhole, through cleaning, Pre-TV, lining, Post-TV, and Warranty-TV, before assuming the others match.
WBDG publishes UFGS 33 01 30.16: TV Inspection of Sewer Lines as a public guide-specification reference (accessed November 10, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| Segments, manhole IDs, and the three drawing notes | System Description (existing mains included in the contract documents) + Entry Point, Exit Point, and Pipe Segment definitions (pipe only, wall to wall) + Sewer Line Cleaning note (segments needing heavy cleaning on the drawings) + Manhole or Structure Cleaning note and bracket + Root Removal note (sections, manholes, or structures needing root removal, from the CCTV field investigation report) + rehabilitation plans and segment schedule | Does every segment to be inspected appear on the plans or in a schedule with the entry and exit manhole or structure IDs, pipe size, and material that the video overlay and the logs must carry, since the section asks the drawings to mark heavy cleaning, manhole cleaning, and root removal but has no note asking for the segment list itself, are the services included or excluded by segment, and where the manholes are to be cleaned or rehabilitated, which section records their condition, since the entry and exit definitions keep every portion of the manhole out of the video? |
| Which inspection phase applies to which work | PART 1 note (Pre-TV during the field investigation and again by the contractor before slip lining; Post-TV and Warranty-TV for slip lining) + Pre-TV, Post-TV, and Warranty-TV definitions + Post-TV note and Post-TV Inspection article (after visual, deflection, pressure and leak testing and service reconnections; documentation timed from liner installation) + Section 33 01 30.72 Examination, Surface Preparation, and Inspection articles + Section 33 40 00 post-installation inspection bracket | Is each phase kept only where another issued section calls it, Pre-TV, Post-TV, Re-TV, and Warranty-TV from Section 33 01 30.72 for relining, and where Section 33 40 00 or another section sends post-installation CCTV of new pipe to this section, has the Post-TV article been edited for new pipe, since its definitions, note, and trigger address slip lining and liner installation only, and is the engineer’s field-investigation Pre-TV video made available to bidders so they can price the cleaning it found? |
| Cleaning, heavy cleaning, debris, and disposal | Cleaning and Heavy Cleaning definitions + Sewer Line Cleaning article (clean immediately before CCTV; report pre-existing damage; clean from the other end; stop and inspect both sides where equipment cannot pass) + Cleaning Equipment and Sanitary Sewer Cleaning Equipment (collapsible dam; no non-collapsible cleaning balls in sanitary sewers) + Disposal Plan + Material Removal and Disposal, Dams or Weirs, Sludge and Debris Storage, and Hauling of Waste Material + Records of Disposals + site plan and disposal sites | Do the drawings distinguish cleaning from heavy cleaning by segment, since the definitions separate them by how full the pipe is and the note says larger pipes typically do not need it, is there a quantity or pay basis for each, is a disposal site and haul route identified or left to the disposal plan, is a dam or weir location available at each downstream manhole where hydraulic cleaning is used, and is the path for a segment that cannot be cleaned from either end, inspection from both sides, defined in the contract? |
| Flow control, bypass pumping, and sewage handling | System Description (by-pass pumping or diversion of sanitary sewer and a sound reduction enclosure for the by-pass pump) + Flow Control, Flow Reduction (bypass pumping as one option), and Floating the Camera + Sanitary Sewer Cleaning (return diverted sewage; no discharge to surfaces, water bodies, or storm drains) + Sewage Handling Permit (tailored for SANITARY) + bypass plan, upstream manholes, force mains, lift stations, and the noise-sensitive uses near pump locations | Since the System Description includes bypass pumping and a sound reduction enclosure but no article specifies either, has the specifier added a bypass article or another issued section, with the flows it must carry, pump and discharge locations, and the enclosure where pumps sit near housing, medical, or other sensitive uses, and since the Sewage Handling Permit paragraph ties the permit first to herbicide application and then to cleaning or pump-and-haul, has it been edited to the operation that actually needs the permit? |
| Roots, herbicide, and pest management | Root Removal note and article + HERBICIDE tailoring notes + Herbicide note (pre-approved by the regional pest management consultant and the wastewater treatment plant operator) and article (highest labeled rate) + Regulatory Requirements (DODI 4150.07, DD Form 1532-1) + Qualifications + Herbicide Application Plan + Chemical Root Treatment, Equipment Calibration and Tank Measurement, and Mixing and Application + Verification of Measurement (established application rate) + Technical Representative + Herbicides closeout | Where herbicide is deleted, have Regulatory Requirements and Technical Representative also been removed, since both concern herbicide only but carry no HERBICIDE tag, where it is kept, is the treatment plant operator’s acceptance recorded, which the note requires but the submittal list does not, is one application rate stated, since the Herbicide article calls for the highest labeled rate and Verification of Measurement checks against the rate established for the site, and has the calibration paragraph been corrected to require recalibration, since it calls for re-treatment when a calibration that precedes treatment is unsatisfactory? |
| Camera, access, flushing, and traffic control | CCTV Equipment and Pipe Inspection Camera (pan and tilt or side wall scanning camera, footage counter, height adjustment, lighting and reflector, on-screen data) + Camera Operation (counter zeroed at the entry wall; speed limit; winches that do not obstruct the view) + Communication bracket and note (radios and cell phones allowed) + Flush Main (potable water into the upstream structure; disposal under the plan) + Traffic Control (plan where manholes are in or beside a road; hydrant access) + traffic control drawings and site plan | Are the manholes in or beside roads identified so the Traffic Control Plan the article requires can be prepared, is the potable water source for flushing identified and the flush water collection point shown, has the Communication bracket been kept only where radios and cell phones are allowed in the project area, as its note asks, and where pipes are large, dark, or deep, does the camera article, with its reflector and lighting items, match the pipe sizes on the plans? |
| Video, logs, photographs, and PACP coding | Documentation of CCTV Inspection (PACP-compliant data logger, video and audio) + Video Recordings (format, CD or DVD, a segment wholly on one disc, continuous video, required overlay data) + CCTV Video definition + TV Inspection Logs (PACP designations) + Digital Photographs + CCTV Technician’s Qualifications (PACP Operator certification) + References article (DODI 4150.07 only) + owner’s asset management requirements | Has the owner confirmed that the file formats, the disc media the section requires, and the naming of segments match its asset management system, and since the References article lists only DODI 4150.07 and names no NASSCO publication or version, has the specifier said which edition of PACP coding the logs and the operator certification follow, and do the overlay and log fields use the same segment and manhole IDs as the drawings? |
| Defects, repairs, Re-TV, and warranty timing | Defects definition + PART 1 note (point repairs not addressed in this section) + Post-TV Defects and Warranty-TV Defects (items b and c begin with the same condition; Warranty-TV Defects opens with defects found “during the Post-TV inspection”) + Warranty-TV Inspection (Contracting Officer selects segments; minimum share of length bracket) + Re-TV Inspection + Section 33 01 30.72 Warranty and Warranty-TV Inspection paragraphs + point repair drawings | Which section specifies the point repairs the field investigation found, since this one does not, which defects require repair, since the section defines defects but sets no acceptance grade, which follow-up governs after a further defect, since items b and c of both defect paragraphs begin with the same condition and prescribe different responses, has Warranty-TV Defects been corrected to refer to the Warranty-TV inspection, and do the timing brackets here and in Section 33 01 30.72 leave a workable window to complete and submit the warranty inspection before the warranty expires? |
Worked example: a relining job with no bypass article, two Post-TV triggers, and a warranty paragraph that points back
Illustrative example: an installation relines a run of clay sanitary mains under a housing area, with several manholes in a two-lane road and one segment beside a child development center, and the same contract installs a short new storm drain that the issued Section 33 40 00 sends to Section 33 01 30.16 for post-installation CCTV. The rehabilitation plans mark heavy cleaning and root removal but give no segment list, only manhole numbers on the plan, and two manholes share an ID. The issued Section 33 01 30.16 keeps the System Description’s bypass pumping and sound reduction enclosure with no bypass article, keeps HERBICIDE tailoring although the plans show only mechanical root cutting, keeps the Post-TV article unchanged for the new storm pipe, and keeps the Warranty-TV Defects paragraph as printed. The owner’s asset system takes PACP data by file transfer, and the section still requires discs.
Ask the civil engineer to add a segment schedule with unique entry and exit IDs, pipe size, and material, and to correct the duplicate manhole ID before Pre-TV begins. Ask the specifier to add a bypass pumping article, or name the issued section that covers it, with the pump locations and the enclosure beside the child development center, to delete the herbicide paragraphs, including Regulatory Requirements and Technical Representative, which carry no tag, and to edit the Post-TV article for new storm pipe so its trigger and timing do not depend on a liner. Ask the specifier to correct the Warranty-TV Defects paragraph and to choose one response where items b and c conflict, to name the PACP edition, and to replace the disc requirement with the owner’s delivery method, and confirm with the contracting officer that the warranty timing brackets here and in Section 33 01 30.72 agree.
Avoid a false conflict
Section 33 01 30.16 covers cleaning and TV inspection of existing sanitary and storm sewer mains and services, with herbicide root treatment as an option, for the field investigation and around slip lining. The liner, its testing, point repairs, and the warranty itself follow Section 33 01 30.72 Relining Sewers or another issued section, new sanitary sewers follow Section 33 30 00 and the sanitary sewer guide, which on WBDG names no TV inspection, new storm drains follow Section 33 40 00 and the stormwater utility guide, which sends their post-installation CCTV here, and lift stations follow Section 33 32 16 and the sewage lift station guide, so check those before calling a requirement missing. The section does not include the manholes or structures in the video, and has no bypass pumping article, no point repair article, and no defect acceptance grade. Its References article lists only DODI 4150.07 though the text relies on NASSCO PACP; its Warranty-TV Defects paragraph refers to the Post-TV inspection; items b and c of both defect paragraphs begin with the same condition; its Sewage Handling Permit paragraph ties a sanitary permit to herbicide application; its Post-TV definitions and article address slip lining only; two herbicide-only paragraphs carry no HERBICIDE tag; and its calibration paragraph calls for re-treatment, so ask the specifier which wording the project intends before treating a difference as a design conflict.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
