CCTV Inspection & Leak Detection

4K crawlers, acoustic & pressure testing, and GIS deliverables for confident, data-driven decisions.

Overview

See more. Decide faster.

Our inspection teams capture high-fidelity video, code defects to NASSCO standards, and run leak checks so owners can prioritize repairs with confidence. Deliverables slot directly into your CMMS and GIS.

  • 4K robotic crawlers with pan/tilt/zoom heads
  • NASSCO PACP/MACP/LACP coding & scoring
  • Acoustic correlation & pressure tests for leak pinpointing
  • GIS shapefiles + PDF reports + raw video archives

Process

From mobilization to handover

Tight controls ensure usable data and quick owner decisions.

01 • Plan & Permit

Access, traffic control, confined space, and bypass design (if needed).

02 • Mobilize & Setup

Truck unit, crawler, cable reel, ventilation, gas monitoring.

03 • Inspection & Coding

Live capture, defect coding to standards, and clip marking.

04 • Leak Tests

Acoustic correlation or pressure/vacuum testing, stationing logs.

05 • QA & Packaging

Data integrity checks, naming standards, GIS data build.

06 • Handover

PACP DB + PDFs + video + shapefiles; rehab priority list.

Case Study — 12 mi Condition Assessment

Citywide CCTV of vitrified clay & PVC sewers (6"–24"). Acoustic correlation on two trunk mains to confirm suspected leaks near a creek.

  • 1,100+ observations coded; PACP scores normalized to priority tiers
  • Five leaks pinpointed within 3–5 ft; temporary clamps installed same week
  • GIS deliverables imported to city portal; rehab program planned by tier

FAQ

Inspection questions, answered

Data formats, access, and how we minimize disruption.

PACP/MACP databases, PDF summary reports, MP4 video clips, stills, CSVs for CMMS import, and GIS shapefiles/geodatabases with attributes and stationing.

Often yes—during low-flow windows. For trunk mains or high-flow segments we design temporary bypass to maintain service and protect crews and assets.

Acoustic correlation typically narrows to a few feet under good conditions; pressure/vacuum tests confirm integrity and help isolate sections for repair.
