PRIME Approach to Service Delivery

Hinterland Group’s industry-leading PRIME model unifies five critical disciplines:

  • Pipeline Rehabilitation

  • Repair & Replacement of key infrastructure (lift stations, gravity mains, service laterals)

  • Inspection (CCTV, vactor, robotic, and visual)

  • Maintenance (scheduled cleaning and up-keep)

  • Evaluation & Assessment (risk, performance, and planning)

This holistic approach ensures seamless transition across all phases, from discovery to intervention and monitoring. (Source)

Target Markets & Applications

  • Municipal Utilities: Sewer and water system condition assessment, regulatory compliance inspection, force main and gravity main evaluations, manhole and lift station assessments.

  • Property Management & HOA: Preventive maintenance inspections, infrastructure longevity planning, disaster readiness (flood and blockage risk), repair prioritization.

  • Industrial Operations: Process piping assessment, lift station integrity checks, emergency response evaluation, preventative asset management.

  • Airports & Commercial Facilities: Runway and terminal drainage inspection, stormwater management evaluations, business continuity support.

  • Emergency Response: Rapid response assessment after storms, floods, or major pipeline failures to support immediate restoration and insurance claims.

  5. CCTV / Robotic Inspection

  6. Internal video recording, capturing anomalies & related asset data

  7. Professional Condition Assessment

  8. Analyze and classify defects (e.g., cracks, offsets, leaks, corrosion)

  9. Rate severity, assign risk prioritization

  10. Reporting & Recommendations

  11. Generate user-friendly and regulatory compliant reports with prioritized recommendations

  12. Support for budget planning and maintenance scheduling

  13. Rehabilitation/Emergency Action (if required)

  14. CIPP, SIPP, point repairs, replacement, or other trenchless methods by Hinterland’s in-house crews

  15. Ongoing Maintenance Planning

  16. Develop tailored schedules for routine cleaning, inspection, and minor repairs (Source), (Source)

Annual and Preventive Maintenance Plans

  • Customized annual maintenance/inspection programs for municipalities, HOAs, and commercial/industrial clients

  • Maximizes infrastructure lifespan, reduces catastrophic failures

  • Budget-friendly: Early intervention and planned repairs are less costly than emergency response

Project Types & Case Applications

  • Sanitary Sewer Cleaning & Inspection: Restoration and CCTV of sanitary lines for municipalities

  • Stormwater & Drainage Inspections: Collection and outfall line evaluations in flood-prone or high-profile public areas

  • Force Main Assessments: High-pressure sewer/water lines, industrial process mains, airport hydrant loops

  • Lift Station Integrity Testing: Flooded/damaged stations, corroded wet wells, or pump cavitation root cause analysis

  • Manhole & Structure Review: Inflow/infiltration (I/I) studies, corrosion assessment, hydraulic loading

Frequently Asked Questions (FAQ)

Q: What types of systems can Hinterland Group inspect and clean?

  • Hinterland inspects/cleans sanitary and storm sewers, force mains, water distribution pipes, process piping, laterals, manholes, wet wells, and related structures—diameters from 4” up to over 100”.

Q: How does CCTV inspection work?

  • After cleaning, a remote-controlled, high-resolution camera is inserted into the pipe. As it travels, it records video, measures pipe dimensions, and documents all observed defects. Data is geo-tagged and compiled into an actionable report.

Q: Who receives the inspection reports?

  • Reports are provided to the client’s designated technical staff or managers and can be formatted for regulatory submission, capital planning, and insurance claims.

Q: How quickly can Hinterland respond to an emergency?

  • Emergency response is 24/7/365 with a 15-minute guaranteed callback and rapid on-site mobilization.

Q: Can inspection and cleaning be performed in live (flowing) sewers?

  • Yes. For many municipal and industrial assets, Hinterland uses in-house bypass pumping to maintain service while performing inspection/rehab tasks.

Q: Do you subcontract cleaning, CCTV, or rehabilitation?

  • No. All core technologies and labor are performed by Hinterland Group’s own highly trained, in-house teams.

Q: Is regular cleaning required before every inspection?

  • Yes, to obtain meaningful CCTV findings and to avoid missed defects or false readings, full cleaning is best practice prior to internal video inspection. (Source)

Q: How does condition assessment inform maintenance planning?

  • By identifying and rating defects early, assets can be scheduled for repair, rehab, or replacement in priority order—reducing risk of catastrophic failure and optimizing capital deployment.

Q: Are specialized programs available for different industries?

  • Yes. Maintenance and inspection schedules are fully tailored for municipal, HOA, industrial, commercial, and airport clients. (Source)

Q: What happens if you find critical or catastrophic defects?

  • Hinterland’s in-house trenchless crews are immediately available for point repairs, CIPP lining, bypass pumping, emergency stabilization, or full replacement—minimizing downtime and public risk.
