Pioneering Remote Pipeline Inspection

The Original MSI Platform

RedZone has pioneered the industry with a suite of multi-sensor inspection (MSI) products designed for large interceptors and tunnels. MSI data quantifies critical problems like corrosion and debris levels that traditional, visual-only CCTV inspection cannot detect. The Responder® unit can traverse through assets that most conventional units cannot.


Designed for Large Interceptors and Tunnels

  • Premium bend radius analysis
  • Laser/Sonar topographical graphs
  • Accurate corrosion/debris mapping
pipe/manwaterlevelmin access

Inspect Pipelines Previously Thought Inaccessible

Interceptors are the backbone of any city’s sewer infrastructure, and are the most expensive to clean, maintain, and rehabilitate. They also present the highest consequence of failure within any system, which is why they demand proactive maintenance and management. That’s why RedZone engineered the Responder.

Fully Submersible

The RedZone Responder is capable of inspecting in even the most difficult conditions, including pipes and system assets that are completely full of water.


Pioneering Remote Large-Diameter Pipe Inspection

Responder is a unique, remotely-operated solution for the inspection and rehabilitation of large diameter pipes and tunnels. With the combination of a robust design incorporating on-board hydraulic capabilities, Responder’s 3D scanning LIDAR, coupled with Sonar, high resolution CCTV, gas, and temperature sensors can collect information on pipe condition in even the most demanding environments. This allows for a thorough assessment of pipe conditions.

Industry Leaders in MSI Technology

Sometimes a picture alone does not tell the whole story. Pioneered by RedZone, multi-sensor inspections (MSI) combine conventional CCTV with synchronized laser and sonar dimension information. This unique, full 360 degree, quantitative view of the pipeline can help to pinpoint which lines in your system require immediate attention, thanks to accurate measurements of corrosion, debris, and ovality.

Guaranteed Return on Investment

The information collected through MSI requires no costly by-passing, shutdowns, or manned entry and ensures that municipalities are not only collecting the best information available, but drastically cutting expenses and ensuring the safety of their workers.

What Customers Are Saying

With RedZone’s proven MSI technology, the Fort Worth Water Department has saved $2.9 million in large diameter cleaning cost to date. It is estimated that the ICAP (Interceptor Condition Assessment Program) methodology of “inspect-to-clean” will result in a savings of $15.2 million in cleaning costs over the six year program.

The data that would have taken us 15 years to gather by conventional televising methods, now took only 15 months
