Managing Sewer Blockages & Preventing Overflows: How Utilities Have Adopted Technology to Win
PART 2 - Technologies and Applications
September 29, 2020 @ 12 Noon EDT, 11 AM CDT, 10 AM MDT, 9AM PDT

Blockages are a leading cause of sanitary sewer overflows (SSOs), often resulting from grease, roots, and debris build-up. As a key focus of managers and supervisors, collection system O&M maintenance processes are built around their prevention and can consume as much as 60% of the operations budget.
Faced with limitations to funding, personnel and time, utilities seeking relief have adopted more sustainable and productive technology-based solutions that alleviate these limitations and improve SSO prevention.
This technology-based O&M solution, its supporting technology, and its positive financial impact is presented in a two-part webinar series appropriate for directors, managers and supervisors.
Duration: 50 minutes with up to 10 minutes of Q&A to follow
Part 1 discussed the traditional concept of sewer cleaning using a schedule-based approach, as well as a concept to optimize it using a data-driven approach. It touched on various enabling technologies, such as remote sensing, the Internet of Things (IoT), and Machine Learning (ML). A closer look at remote sensing and related IoT technologies was provided, setting the stage for a more detailed discussion of ML.
Part 2 provides a quick overview of Part 1, then dives into a deeper discussion of ML, where we use an ML-based application in sewer blockage prediction as a case study. While ML is a commonly used phrase today, it is often not completely understood how it works in wastewater applications, and more importantly, the benefits that can be realized. Examples of this technology in operation are provided, allowing collection system managers and supervisors to see how to use Smart Water technology to make informed decisions.
Case studies are illustrated through several business cases that include quantifiable productivity measures and return on investment.

The purpose of Part 1 is to provide a basic understanding of scattergraphs, including the fundamentals on which they are built. An overview of uniform flow conditions is provided, as well as the Manning Equation that represents them. Insights that can be gained by viewing flow monitor data through the lens of the Manning Equation will also be discussed. Important things can be learned by noting when they agree and when they disagree. These fundamentals provide a basic understanding of scattergraphs and serve as building blocks to more advanced principles to follow in this webinar series.
The purpose of Part 5 is to discuss the practical application of the Froude Number to flow monitoring. Engineers are aware of the instability associated with critical flow conditions and are generally advised to avoid them during sewer design. However, such conditions are often encountered in existing sewers and can impact the reliability of flow monitor data.
The Froude number (Fr) is a dimensionless number used to describe flow conditions within a sewer. These conditions can be illustrated on a scattergraph using iso-Froude lines. Certain flow conditions such as hydraulic jumps, sewer bores, and undular jumps are readily identified by evaluating flow monitor data with respect to iso-Froude lines. Practical examples from flow monitor locations are provided, demonstrating the scattergraph signatures of various transcritical and near-critical phenomena. Flow monitors can operate well in sewers under subcritical and supercritical condition, but accuracy may deteriorate near the transition. Such conditions should be avoided when possible in flow monitoring applications.
