Inspection & Assessment for Water & Wastewater Infrastructure

Informed decisions start with the right data

Early diagnosis is the key to maintaining performance, safety, and regulatory compliance in water-related assets. Whether in dams, pipelines, or treatment plants, timely inspection helps detect hidden deterioration before it escalates.

VSL provides condition assessments using advanced diagnostic techniques tailored to water environments. Our teams work in fresh and wastewater contexts, above and below ground, adapting methods to each structure’s material, accessibility, and operating constraints.

Our inspection & assessment services

We provide targeted diagnostics to evaluate condition, detect deterioration and damage, and support informed decision-making, using both visual methods and advanced testing tools.

Including confined space and underwater access, with crack mapping when required

Such as GPR, ultrasonic, impact echo, and corrosion potential measurement

Including hydrostatic and operational stress assessments

For deeper analysis when non-invasive methods are insufficient

Why inspect with VSL?

  • Hydraulic & structural know-how

    We combine expertise in water-related deterioration and structural behavior across all materials.
  • Specialized access capabilities

    From reservoirs to shafts, we use advanced tools (like drones), safe access systems and rope teams to reach hard-to-inspect areas.
  • End-to-end support

    We guide clients from initial diagnosis to repair design and prioritized action plans, always with long-term durability in mind.

FAQs about water infrastructure assessment

Below are answers to frequently asked questions about the inspection of water infrastructure. Contact us if you’d like to discuss further.

Inspection frequency depends on asset type, criticality, and environment. Most structures benefit from visual inspection every 1-2 years, with in-depth assessment every 5-10 years. Ideally, this is defined in an Inspection & Maintenance Plan – and if none exists, we can support clients in creating one in line with the latest standards and international recommendations.

We apply non-destructive testing (NDT), including radar, ultrasonic and impact echo, to identify issues not visible from the surface.

Yes. We plan around operational constraints and can often inspect while assets remain in service. When this is not possible, we are fully equipped to conduct inspections during downtime, ensuring a comprehensive evaluation aligned with operational requirements.
