Turnkey Pipeline Cleaning, CCTV/PACP Inspection, and Trenchless Rehabilitation

Introduction

A single-vendor, end‑to‑end workflow minimizes risk, accelerates schedules, and improves closeout quality for underground utilities. Hinterland Group’s PRIME service model—Pipeline Rehabilitation, Repair/Replacement, Inspection, Maintenance, and Evaluation—lets owners move from debris removal to PACP‑coded inspection through rehabilitation and preventive maintenance without changing contractors. See service overviews on the Services and Maintenance Plans pages.

End‑to‑end workflow (clean → inspect → rehabilitate → maintain)

1) Scoping and mobilization

  • Project intake, traffic control planning, utility coordination, and safety planning.

  • Bypass design and turnkey delivery when needed via in‑house capabilities. See Repair & Replacement.

2) Cleaning (vactor/hydrojet)

  • Restores flow and prepares lines for inspection.

  • Scheduled programs reduce emergency risk; details at Maintenance.

3) CCTV/PACP inspection and condition assessment

  • Robotic camera inspection following a clean‑first approach; synchronized video, observations, and defect coding for decision support. See Inspection and Evaluation & Assessment.

4) Rehabilitation method selection (same vendor)

  • After PACP review, Hinterland selects the least‑disruptive, most cost‑effective trenchless method based on host pipe, defect class, hydraulics, and access. Methods are performed in‑house; see Pipe Rehabilitation.

5) Trenchless construction options (performed in‑house)

  • Cured‑in‑Place Pipe (CIPP): Structural renewal with minimal excavation; capabilities include small‑ to large‑diameter installations, with documented installs up to 108 inches and EcoLiner options in regional programs. See CIPP South Carolina and CIPP Georgia.

  • Geopolymer spincast (spray‑applied structural liner, SAPL): For corrosion, infiltration, and shape restoration in gravity assets; excellent for manholes, large sewers, and culverts. See Pipe Rehabilitation.

  • Sliplining: Inserts a new carrier pipe into the host for added structural capacity and corrosion resistance. See Pipe Rehabilitation.

  • Pipe bursting: Trenchless replacement to upsize/replace brittle or failed segments with minimal surface disruption. See Pipe Rehabilitation.

6) QA/QC and closeout deliverables

  • Method‑specific testing (e.g., CIPP cure logs), final inspections, punch list completion, and as‑constructed documentation.

7) Preventive maintenance cycle

Deliverables (what you receive)

  • Pre‑ and post‑cleaning inspection videos with synchronized observation logs.

  • PACP‑coded inspection reports and condition summaries to support rehab selection.

  • Method submittals and QA records (e.g., resin/cure logs for CIPP; mix/thickness logs for geopolymer spincast).

  • Final closeout package with post‑construction video, acceptance testing results, and recommended maintenance schedule.

Asset ID Segment From–To Dia (in) Material Length (ft) Inspect Date Defect Code Grade Infiltration Remarks
MH‑12‑A MH‑12 to MH‑13 12 PVC 245 2025‑09‑14 IRB‑L 2 No Minor root intrusion at lateral, trimmed.
MH‑13‑B MH‑13 to MH‑14 15 RCP 310 2025‑09‑14 FX‑C 4 Yes Longitudinal fracture at crown; recommend CIPP.
MH‑14‑C MH‑14 to MH‑15 24 CMP 180 2025‑09‑15 CL‑W 3 No Corrosion/lamination; consider geopolymer spincast.

QA/QC checklist (excerpt)

  • Pre‑clean and post‑clean flow verification (photos/video timestamps recorded).

  • CCTV calibration check, lens clarity check, distance counter verification.

  • PACP observation coding reviewed and approved by qualified reviewer.

  • Traffic control and confined space permits on file; daily JHA completed.

  • Rehabilitation submittal approvals on file (resins, liners, mix designs, thickness calcs).

  • Cure/spin/thickness logs collected; samples taken per method requirements.

  • Final post‑rehab CCTV completed and accepted; punch list closed.

  • Closeout binder delivered (digital + hard copy as requested) with maintenance plan.

Why a single vendor for clean + inspect + rehab

  • One mobilization, fewer handoffs, and tighter change‑management controls reduce cost and schedule risk.

  • All trenchless methods performed in‑house for method‑agnostic recommendations and single‑source accountability. See Pipe Rehabilitation.

  • Integrated bypass pumping and electrical support accelerate complex lift‑station and gravity work. See Repair & Replacement.

  • 24/7 emergency response and documented rapid mobilization in regional programs (e.g., 15‑minute callback and mobilization within 24 hours). See CIPP South Carolina and CIPP Georgia.

  • Safety‑first culture with OSHA‑focused programs and experienced teams. See About.
