Case Study: Inflow and Infiltration and Wet Weather Flow Reduction of Pilot Areas (Part 3)

Sewer Inspection

Parts 1 and 2 of this case study offered a detailed summary of wet weather inflow and infiltration (I/I) reduction pilot projects undertaken by Civica for the City of Toronto. Part 2 specifically delved into technical, financial, and SWOT analyses. Part 3 will address the project management strategy and sewer capacity analysis, concluding with recommendations […]

Case Study: Basement Flooding Area 9 Inflow and Infiltration Reduction

Civica Infrastructure Inc. collaborated with the City of Toronto on inflow and infiltration (I/I) reduction projects involving two pilot areas: Area 9 in Etobicoke and Wirral Court in Scarborough. When excess water enters the sewer system due to heavy rainfall or damaged pipes, the water levels can become too high for the system to handle, […]
