Historically, the most common renewal method has been to replace the pipeline using open-cut construction. A lack of investment in the aging pressure pipe infrastructure, coupled with growing congestion above and below ground, has accelerated development in the trenchless rehabilitation industry. With an array of proven trenchless rehabilitation technologies, how does a utility owner or engineer determine the appropriate technology? This presentation will briefly review the common and emerging trenchless technologies for pressurized pipeline rehabilitation. Then, it will provide a basic framework that can be used to evaluate and select an appropriate solution. We’ll review the concept of structural classification of pressure pipe linings as defined in American Water Works Association (AWWA) publications, which is a critical component to selecting an appropriate trenchless technology. We’ll also review a few case studies that demonstrate how the basic framework was followed to select a trenchless technology solution.
Read MoreTo keep a stormwater program from drowning in its data, it’s essential to manage information so it’s easily accessible and can help drive critical decisions. The Town of Apex, NC, is using data management tools to automate and streamline its stormwater information in a way that has improved operations and, more importantly, helped with municipal separate storm sewer system (MS4) compliance. Apex worked with Freese and Nichols to develop a Survey123 and ESRI Field Maps mobile app that serves an array of functions: tracking, logging, adding and storing data; collecting photographs; spatially locating assets; performing real-time assessments; and using custom scripts to automate triggers that generate stormwater control measure (SCM) inspection reports. The system can automate 30-day reminder email notifications to property owners informing them of their upcoming annual SCM inspection. These tools and a custom dashboard allowed for daily quality and progress checks. As a result, the Town of Apex organized its stormwater data to meet MS4 compliance.
Read MoreEach year, CPWA develops public policy priorities to inform its work advocating for public works to federal government departments and officials. This session will provide a brief overview of past activities and the current priorities of the federal government as well as an opportunity for facilitated discussion and knowledge exchange. CPWA Board members will facilitate small group discussions among attendees focusing on CPWA’s existing policy priority areas as well as possible new areas of focus. Attendees will be encouraged to share their experiences, including the challenges they face, so that CPWA can more effectively advocate for recognition and solutions.

Each community seems to have that one spot that always has crashes when winter weather arrives, or bridge that behaves differently than all the others at night. Why is that?…

Read MoreThis session will offer an introduction to the City of Dublin, Ohio’s snow and ice response plan known as SnowGo. The speaker will discuss how to create a positive interaction with all municipal divisions for a 360-degree response to snow and ice events. The session will include information regarding planning, preparation and execution of the SnowGo plan from preseason training events to an end of season celebration. Equipment and material information used by the community will be highlighted, and a remedy to prevent aggregate and debris being transferred from brine makers to holding tanks will be shared.
Read MoreIn November 2021, the U.S. Congress passed, and President Biden signed into law a bipartisan infrastructure bill known as the Infrastructure Investment and Jobs Act (IIJA). Infrastructure investment has been a ”hot topic” for years on Capitol Hill and now with the IIJA comes $550 billion in new federal funding for infrastructure priorities over five years. Specifically related to APWA’s public policy priorities, the association was successful in advocating for the increased federal investment, continued streamlining and reduction of duplicative permitting process, efforts to strengthen the overall resiliency of our nation’s infrastructure to best stand against both natural disasters and cyberattacks, and a robust investment in upgrading water and wastewater systems while protecting them from dangerous emerging contaminants. What does all this now mean for public works professionals? Join members of APWA’s Government Affairs team for a session focused on providing a current update on implementation of the new law, the APWA policy process, and how to best advocate for public works priorities at every level—local, state, and federal.
Read MoreThe City of Raytown needed an asset management strategy for its sanitary sewer system. Raytown’s sanitary sewer system serves 30,000 residents. The system includes 165 miles of gravity sewer lines, 4,325 manholes, two miles of force main, and two equalization basins, each with six million gallon capacity. There are no combined sewers. The City engaged with NEER.ai to use a machine learning (ML) solution to identify the risk condition. NEER created and applied several ML techniques (clustering, classification, and regression) to populate missing values and score likelihood of failure (LoF), consequence of failure (CoF), and overall risk score for each sanitary sewer asset. NEER.ai produced more than 90% accuracy in predicting the LoF score for sanitary sewer assets. NEER also calculated CoF and the overall risk of the entire system. The City of Raytown saved several thousand dollars and significant staff hours by leveraging ML to implement its sewer asset management program.
