Infiltration and Inflow Measurement and Methods Series
Have an infiltration and inflow (I/I) problem? You are not alone. Most wastewater collection systems do, and an I/I study is often the first place to start. Join ADS for a six-part webinar series taught by experienced professionals where you will learn how to plan and execute successful I/I studies. The first two webinars will focus on planning, mobilization, and monitoring, while the following four webinars will discuss evaluation methods used to characterize rainfall events and understand dry weather and wet weather sewer performance. I/I studies are fundamental to the success of subsequent condition assessment and rehabilitation programs. Learn how to plan and execute them with confidence to guide and assess the programs that follow.

Sewer Sociology®: Tracking the Pandemic Through the Eyes of a Sewer
The COVID-19 pandemic has run its course for almost two years now and has upended all of our lives. The normal that we once knew is simply not normal anymore. Instead, our usual routines at home, work, and school have been replaced by new ones involving masks, social distancing, testing, and vaccination – all in a collective effort to beat back the virus.
As sewer sociologists, we have spent much of the past 15 years studying human patterns of normal and departures from normal through the lens of water and sewer use. So as the pandemic began, we knew we were in a unique position to observe the pandemic and its effect on society from a unique perspective. Join us for this webinar as we discuss the impacts of the pandemic through the eyes of a sewer and what they tell us about our hope for a return to normal.

Scattergraph Principles and Practice
The scattergraph is a powerful tool that displays depth and velocity data from a sewer flow monitor, and the resulting patterns form characteristic signatures that provide insight into conditions within a sewer. Last year, ADS hosted a comprehensive webinar series designed to educate wastewater professionals to use scattergraphs to recognize various flow conditions in sewers and understand how they impact sewer capacity and performance. This webinar supplements that series with the release of the latest edition of our popular Scattergraph Principles and Practice Poster. Join Patrick Stevens and Kevin Enfinger as they demonstrate how to use the poster and provide a guided tour. This webinar is both informative and fun and will include tips and tricks, some hidden nuggets of wisdom, and a few behind-the-scenes stories.

The Big Debate: Can Depth-Only Devices Be Used for I/I Work?
From the ancient Egyptian Nilometer to Robert Manning’s Manning Equation to Peter Petroff’s Doppler velocity sensor, humans have long sought ways to quantify the flow of water by measuring its depth. New depth-only devices on the market today are being touted as new technologies for chasing I/I. Engineering and operations staff find them attractive because of their lower cost and no confined space entry. However, they rely on the Manning Equation which was virtually abandoned 40 years ago in favor of area-velocity (AV) flow meters in I/I work. These depth-only devices can be very useful, but when used improperly can cause you to look for I/I in all the wrong places. This webinar will provide case studies presented by several different speakers, and a moderated panel discussion will follow.
