Infiltration and Inflow Measurement and Methods

Part 3 – Evaluating Rainfall Data
Thursday, April 22, 2021 @ 12N EDT, 11am CDT, 10am MDT, 9am PDT

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.

Duration: 50 minutes with up to 10 minutes of Q&A to follow

Following successful planning, mobilization, and monitoring, I/I can be evaluated to target the most problematic areas of the wastewater collection system for further investigation, inspection, and rehabilitation. The first step is to evaluate rainfall data obtained during the monitoring period. This webinar will discuss the definition of a rainfall event and the characteristics of rainfall events most important to I/I evaluation. Comparing rainfall events to rainfall depth-duration-frequency (DDF) and intensity-duration-frequency (IDF) data will also be discussed, along with spatial distribution methods available to extrapolate point-source rainfall measurements to areal rainfall estimates associated with the study area.

Following the initial planning for an I/I study, it is time to deploy flow monitors and rainfall monitors and gather crucial data needed for successful evaluation.  Part 2 of this webinar series is a panel discussion that provides important insight on what to do and what not to do in this critical phase.  Panelists include ADS project managers and engineers who understand the administration, management, and technical aspects of I/I studies and have a broad range of experience on projects throughout the United States and Canada.

Part 1 provides a framework to help you plan for a successful I/I study.  One of the most important planning objectives is to estimate the scope, schedule, and budget for the monitoring phase, which requires that several questions be asked and answered.  How many flow monitors are needed?  How many rainfall monitors are needed?  When should I start monitoring?  How long should I monitor?  We will discuss the technical implications of these questions and how they influence the success or failure of an I/I study.  Applying the principles here will allow you to position your next I/I study for success.
