CCTV condition assessment programs, which use robotic camera equipment deployed to inspect pipe segments one at a time, form the backbone of asset management and maintenance operations for sewer and water pipeline systems. Since 2002 NASSCO, the National Association of Sewer Service Companies, has offered the Pipeline Assessment Certification Program (PACP) training and certification courses for CCTV operators, asset managers, and engineers. PACP has quickly become the standard for sewer and storm condition assessments in North America, providing essential information decision-makers use to prioritize and optimize limited resources.
Unfortunately, the PACP is limited by human error and the wide variations in quality of PACP reports produced by different contractors, engineers, and operators in public agencies, not to mention the current workflow of human operators watching every foot and second of video in real-time contributes to approximately one quarter of the total cost to inspect and assess each foot of pipe.
An Artificial Intelligence-based (AI) tool to automatically label defects in sewer inspection videos using the existing PACP standards for defects and features in pipes has recently been developed. This development more than triples the speed of producing condition reports on wastewater, storm, and drinking water assets, while also reducing the total costs of inspection by approximately 50%.
The presentation will describe in detail the AI/Machine Learning processes involved in creating the PACP condition assessment reports using raw CCTV in-pipe data, as well as the major useful applications for the technology.

On April 29, 2021, the Water Security Division will conduct a one-hour webinar for drinking water and wastewater utilities titled, “Prepare for Supply Chain Disruptions: Building a Resilient Water Sector.” This webinar will provide an overview of the carbon dioxide supply chain and the potential threats to this supply that occurred early in the pandemic. The U.S. Environmental Protection Agency will discuss the interdependencies between the water and chemical sector and provide tools and resources to assist utility staff with developing more resilient supply chains. A representative from the Department of Homeland Security will discuss commodity concerns, specifically the use, availability, and distribution of carbon dioxide in the water sector. Finally, Des Moines Water Works will provide lessons learned from a potential carbon dioxide disruption as a result of a local ethanol plant closure in Iowa.

Wastewater monitoring for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging public health tool to understand COVID-19 spread in a community. This is because SARS-CoV-2 can be shed in the feces of infected individuals from both symptomatic and asymptomatic cases, eventually ending up in the wastewater. The objectives of this project were to (i) develop and implement methods to monitor SARS-CoV-2 in wastewater and (ii) examine the levels of the SARS-CoV-2 in wastewater facilities in Southeast Louisiana and develop key relationships with cases in the community to support public health decisions to manage and prevent the spread of the disease. Weekly composite wastewater samples have been collected from 5 wastewater treatment plants for the analysis of SARS-CoV-2. The results and experience of monitoring SARS-CoV-2 in wastewaters in 4 cities in Southeast Louisiana will be presented.
