Make it substantially easier, better, faster, safer, cheaper and with deeper levels of insight to more accurately inspect and assess sewers

AquaTwin DDM

An extension of AquaTwin Asset, AquaTwin DDM (Digital Defect Modeling) is the next-generation self-service software for automated sewer inspection and condition assessment. Now for the first time, you can instantly turn your pipe inspection images and videos into detailed 3D models of defect characteristics (e.g., cracks, joint offsets, debris, roots, corrosion, deflections, deposits, obstacles, infiltrations), automatically quantify severity (estimate length, area and depth), grade and score based on NASSCO PACP standards. No training data or past images needed. No manual review. Applicable to any pipe material.

Powered by cutting-edge automata theory, AquaTwin DDM leverages your existing CCTV videos to create detailed 3D models of your sewer pipes showing the location and severity of all defects along with critical information such as defect length, area and depth so you can proactively plan repair. You can now accurately detect and classify defects in wastewater and stormwater sewer networks to properly evaluate their physical and functional condition and optimize and prioritize rehabilitation and replacement decisions. What’s more? Extremely easy to use self-service tool, you can get up and running quickly and start making better, more informed and timely decisions that will lead to financial, operational and business success, and more reliable performance at maximum cost savings.

Take Control and Turbocharge Your Sewer Inspection and Condition Assessment


Rehabilitation of aging sewer systems is of primary concern for municipalities to ensure normal operations and services on a continuing basis. Let AquaTwin DDM supercharge your wastewater and stormwater inspection analysis and condition assessment to automatically find, quantify and prioritize defects and monitor deterioration over time to determine where intervention is needed the most. Recognize problems sooner and evaluate inspection data faster, more accurately and prevent sewer main breaks, overflows, sinkholes, property damages and other emergencies and keep your sewer infrastructure operating efficiently well into the future.

Unlike Artificial Intelligence (AI) based software that employ tools such as machine learning algorithms requiring thousands of forensic images training data sets to recognize instances of defects in images, AquaTwin DDM uses rigorous automata theory to automatically locate and estimate defects (length, area and depth) faster, more accurately and with deeper levels of insight. AI-based inspections are also prone to hidden biases derived from the data provided to train the system. Similarly, it is undefined how much training is good enough as more training may lead to more false positives and worse results. In addition, AI-based tools are unable to compute the outlines of structural defects such as crack areas, lengths and depths – information essential to evaluate and monitor defect severity and deterioration over time.

Centralized Inspection

Visualize, analyze and manage all inspection and condition assessment work in one location – the ArcGIS geodatabase – and improve safety, efficiency and collaboration.

Rigorous Defect Detector

Use breakthrough explicit mathematical algorithms to automatically create detailed 3D models of defects, estimate their lengths, areas and depths faster, more accurately and with deeper levels of insight.

Streamline CIP

Automatically grade and score defects and determine LOF risk to proactively pinpoint where intervention is needed the most. And optimize your asset management program.

Minimize Costs & Errors

Dramatically cut down inspection review time and condition assessment work with incredible speed and accuracy. Eliminate human errors, fatigue, distractions or operator bias.
