A Long-Distance Sonar Platform
RedZone has taken its world leading multi-sensor inspection (MSI) knowledge and packaged it in a long-distance sonar platform. Siphons in a sewer system can present a challenge to inspect and maintain. Identification of significant areas of sediment build up within surcharged lines will aid in the planning of cost-effective maintenance. Access between manholes can often span considerable distance, requiring a platform that can capture data over long ranges. Inspections in fully surcharged conditions cannot be undertaken by conventional CCTV crawlers.
Neutrally Buoyant And Hydrodynamic Design
- Deployments of up to 8,000 feet
- Designed for siphons and fully surcharged lines
- 3D presentation views
The MD Sub’s neutrally buoyant and hydrodynamic design is engineered for underwater condition assessment through the use of advanced sonar technology. Volumetric debris, sediment, and water level data can be stored and analyzed with ICOM®. RedZone’s MD Sub provides an additional element to the current MD equipment, either as a stand-alone product or an addition to the MD or Super MD Profilers. Utilizing the same onboard computer and batteries packaged into a robust transportation unit allows for inspections of hard to reach surcharged lines.
More Feet Per Inspection
Conventional sonar platforms require a cable to the surface to control the equipment in the pipe. With all the modular recording components stored within the hull of the MD Sub, inspections are only limited by the battery life of the unit. The nature of the equipment allows for long stretches of surcharged lines to be easily inspected.
The data returned from the MD Sub allows municipal engineers to ascertain the true condition of their underwater assets, identifying and presenting major faults, debris volume and location, and water level. With this information in hand, data driven decisions can be easily made to ensure best practice maintenance and rehabilitation of these critical pipelines.

We hit the pavement with pride.
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.
