Stormwater Sustainability: Funding Alternatives for CLI-ECA Regulations (Part 2)
In the previous post, an overview of Civica’s Stormwater System Sustainability webinar was provided. Part 1 identified and explained the key challenges facing stormwater management systems. Part 2 will take a closer look at the costs and creative funding strategies for sustainable stormwater management programs. Performance and Cost – Sewer Systems It is important to […]
Creating Wastewater System Capacity to Support Housing: Private-Side Inflow and Infiltration Reduction Success
Murari Raghavan (mraghavan@civi.ca), B.Tech, M.Sc., Civica Infrastructure Inc. Matthew Malone (mmalone@civi.ca), M.Sc., MBA, Civica Infrastructure Inc. Introduction The impacts of reduced sewer conveyance and treatment capacity in wastewater systems caused by Inflow and Infiltration (I&I), bring about problems including increased risk of basement flooding, restricted new urban development, increased wastewater operation and maintenance costs, and […]
Flow Monitoring and Its Role in Inflow and Infiltration (I&I) Studies (Part 2)
In the previous post, an overview of Civica’s fourth webinar in the Flow Monitoring Webinar Series was provided. Part 1 explained the role rainfall monitoring plays in inflow and infiltration (I&I) studies. Part 2 will take a deeper look into flow analysis, including dry-weather flow (DWF) analysis and wet-weather flow (WWF) analysis. Flow Analysis When […]
Stormwater Management Facility Sediment Efficiency Monitoring Using Innovative Forecasting and Sampling Techniques (Part 2)
In part one, the ways in which stormwater management facility sediment efficiency monitoring could be improved were examined. Part one covered: Flow monitoring Rainfall monitoring TSS Sampling TSS Removal Efficiency Analysis Sample Size Sampling Locations Part two will examine the grab sampling methodology and the benefits for municipal wastewater management when using a semi-automated process […]
Impacts of Existing Storm Drainage Design Standards in Ontario on Sanitary System Capacity (Part 2)
In the previous article, we discussed how storm drainage design standards can impact wastewater systems. In this article, we’ll be looking more in-depth at stormwater drainage, specifically risk factors for sanitary maintenance holes (and by extension sewage flooding and basement flooding), as well as provide some recommendations on how to prepare your sanitary sewer systems […]
Impacts of Existing Storm Drainage Design Standards in Ontario on Sanitary System Capacity (Part 1)
Municipal sanitary sewer systems need to be designed to specifically account for large rainfall events, otherwise there is a potential for wastewater flooding during these storms. In other words, sanitary systems need to be designed with storm drainage in mind in order to prevent flooding. Sanitary maintenance holes are designed to account for some storm […]
