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

AquaTwin DCI

An extension of AquaTwin Asset, AquaTwin DCI (Digital Condition Inspection) 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), code, grade and score based on NASSCO PACP standards. No training data or past images needed. No manual review. Applicable to any pipe material.

A turn-key product and powered by cutting-edge automata theory, AquaTwin DCI 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 type, 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.

A Picture is Worth a Thousand Words

Rehabilitation of aging sewer systems is of primary concern for municipalities to ensure normal operations and services on a continuing basis. Let AquaTwin DCI 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 DCI uses rigorous automata theory to automatically locate, code and estimate defects (length, area and depth) faster, more accurately and with deeper levels of insight. AI-based inspections are not able to determine if cracks go through the pipe wall resulting in true leak locations and 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.

AquaTwin DCI is predicated on rigorous image processing Automata Theory to identify pipe defects and quantify their severity. It is designed to efficiently recognize boundary patterns in high noise images like in grainy CCTV videos. Such high noise pattern recognition capability is particularly useful in effectively processing a wide range of video qualities – from grainy to sharp and from dim to well-lit videos.

  • Recognizes patterns in high noise CCTVs.
  • Quantifies light and shadows for defect classification and depth estimation.
  • Identifies different NASSCO classes/categories of defects with low cross-over misidentification (e.g., surface damage vs. crack).
  • Within a NASSCO category (such as surface damage or breaks) quantifies the degree of severity based on geometric information (e.g., boundaries, depths).
  • Produces results with low false positives and high true positives.
  • Quickly processes CCTV videos 10x to 100x faster than normal play speed.
  • Requires no training which saves time and money.
  • Processes all standard CCTV video formats including 4K video resolution.
  • Scans individual CCTV or batch run CCTVs.
  • Extends existing condition inspection data.
  • Track deterioration over time.
  • Automatically find defects and estimate their types, lengths, areas and depths.
  • Work for any pipe material.
  • Use rigorous computational automata algorithms. Get up and running immediately. No training data needed.
  • Automatically code, rate and grade pipe condition based on defect type and severity
  • Quickly compare results with NASSCO scores
  • Identify defects missed by visual inspection, computer vision or NASSCO coding
  • Locate material changes
  • Validate coding, flag potential coding errors and detect missed codes
  • Perform QA/QC of the defect coding, diagnose problems, and continuously monitor and visualize the health of your sewer system.
  • Stream CCTV media (photos and videos) from the cloud and free-up valuable space on your local drive.
  • Perform in-depth analysis of your inspection data and structural condition of your pipes.
  • Import non-PACP standard (any format) survey data from various data sources.
  • Instantly create detailed heat maps highlighting red flags requiring immediate attention.
  • Enable more effective and efficient condition assessment, CIP and O&M Plan development.
  • Directly leverage defect results in failure modeling and risk planning.
  • Use detailed queries for highly specific planning.
  • Results can be directly used in failure modeling, determining likelihood of failure as well as in renewal and replacement (R&R) diagrams to optimize CIP and O&M planning. They can also be compared with past inspections for improved decision making.
  • Display, review and analyze results using dynamic analytic tools including vivid dashboards, heat maps, color coding, 2D and 3D mapping, tables and reports.
