RedZone pioneered and continues to lead the industry with a suite of multi-sensor inspection (MSI) equipment. MSI data quantifies and identifies critical problems, such as corrosion, deformation, and debris levels, that can be missed by visual-only, traditional CCTV inspection.
With infrastructure aging around the world, wastewater engineers are required to maintain a constant understanding of their network. Through the use of MSI equipment, accurate empirical data on the wall loss or deformation within buried assets can be ascertained. No longer will the subjectivity of CCTV images mean considerable expenditure based on an operator’s judgement or the severity of defects. Laser data is collected with synchronized sonar information beneath the flow. Sonar readings provide the volume and location of debris within the network, data vital in creating a targeted cost-effective cleaning program.
RedZone’s reporting system is based upon the topographical flat graph. All of the data collected is presented on the color coded representation of the pipeline from manhole to manhole, split and unrolled at 6 o'clock. Reds, oranges, and yellows indicate where the data is outside the set pipe diameter (corrosion), and blue indicates points inside the reference (debris).
To start the process of creating a 3D Engineering Report, all MSI data is combined into a comprehensive 3D model of the pipe and related infrastructure (junction chambers, manholes, and other structures). Not only does this model include measurements of the pipe’s cross-section size and shape at every point, but the model also includes bends in the horizontal and vertical planes. Once the 3D Model is assembled, CAD and other specialized tools can be used to help answer questions and perform "what-if" analyses regarding potential rehabilitation techniques.
3D modeling displays pipeline and chamber locations. Results can be provided in a variety of formats, along with dimensional drawings.
Identifies bend radius/curvature to show location and alignment deflection angle of each bend in the pipeline. Also identifies geometry size and shape.
Virtually test the viability of different lining parameters, providing information on clearance and liner-liner deflection angles.
Coupling bend radius information with known GPS coordinates, the report shows the pipe’s center line and manholes using real-world positioning.
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.
