CCTV inspection for public works and sewer networks

Technical diagnosis of pipelines in public works

CCTV inspection is widely used in public works and sewer networks to assess the condition of underground pipelines without excavation.

This type of inspection allows the precise identification of issues such as settlement, infiltration, cracks, deformation or blockages, making it a key tool for managing and maintaining underground infrastructure.

Application in public networks and infrastructure

In public works, CCTV inspection is typically used to analyse sewer collectors, stormwater drainage systems and large underground pipelines.

The goal is to evaluate both the structural and functional condition of the network, helping to plan interventions, prioritize repairs and prevent major failures.

• overall condition assessment of pipelines
• identification of construction defects
• detection of infiltration and leakage
• identification of settlement and deformation

REVIPOX approach

Although the technology is the same, REVIPOX does not operate directly in public works contracts or formal inspection tenders.

Our focus is on private networks, buildings and condominiums, where CCTV inspection is used to diagnose real issues such as leaks, recurring blockages or pipe deterioration.

In practice, this means our work is focused on:

• understanding the root cause of the problem
• evaluating the impact of defects
• defining the most appropriate technical solution

From inspection to technical decision

Unlike inspections focused only on recording and classification, REVIPOX inspections are decision-oriented.

Each inspection is analysed to determine whether the solution involves cleaning, localized repair or trenchless internal rehabilitation, avoiding unnecessary interventions.

When this type of inspection makes sense

Even outside public works, this methodology is highly effective for underground networks in buildings and condominiums, especially when problems are recurring or difficult to diagnose.

CCTV inspection turns uncertainty into clear information, ensuring that any intervention is based on the real condition of the pipeline.
