Case Studies: Wet Weather Inspections to Find Inflow and Infiltration (I&I) – Part 2
The first part of this webinar delved into the diverse factors contributing to the problems of inflow and infiltration (I&I), inflow and infiltration methods, and onsite inspections, with a focus on field inspections conducted during wet weather conditions. This second part outlines some specific cases of wet weather inspections that Civica conducted. Case Study 1: […]
Collection System Modelling Utilizing Flow and Rainfall Data (Part 2)
In the previous post, an overview of Civica’s fifth webinar was provided. Part 1 explained how Ontario’s infrastructure growth and climate changes are affecting collection systems and wastewater management. Part 2 will take a deeper look into flow data and the different models used to assess dry-weather flow (DWF) add wet-weather flow (WWF). Why Use […]
An Overview of the New Subdivision Flow Monitoring to Assess Performance of Inflow and Infiltration (I/I) Prevention
All wastewater collection systems are designed to convey water to a designated point. They are meant to allow for a small amount of extraneous inflow and infiltration (I/I). But more often than not, there is higher I/I than anticipated and can present capacity issues to the sanitary sewers. That’s what makes new subdivision flow monitoring […]
5 Key Insights Into the New System-Wide Sanitary ECA Regulations
If you want to effectively navigate the new Consolidated Linear Infrastructure Environmental Compliance Approval (CLI-ECA) to better take advantage of the improved regulatory process, then you’re in the right place. In this piece, we’ll focus on some key insights into the CLI-ECA sanitary regulations and how municipalities can be proactive, identify risks, and set up […]
Learn about the City of Toronto’s Sewer Infrastructure and Sewer Assessment Guidelines
In order to comply with the City of Toronto’s guidelines (as well as follow best practices when it comes to sewer maintenance and/or land development), you need to understand how a sewer capacity assessment works. Otherwise, your project may encounter unanticipated roadblocks or, the sewer system may face a number of costly issues, such as: […]
Why and When Should You Perform a CCTV Sewer Inspection?
Maintaining the health and integrity of your sewer systems is critical to avoiding expensive and damaging issues, such as flooding and pipe collapse. But these systems, particular the pipes under the street, are difficult to monitor by nature of them being sealed and often hidden under other infrastructure. But that’s where a CCTV sewer inspection […]
