Investigation Methodology for Determining the Root Cause of Inflow & Infiltration (I&I) – Part 2
Identifying and mitigating inflow and infiltration (I&I) in our aging wastewater systems is one of the most pressing challenges facing civil engineers, municipalities, and land developers today. With excess stormwater and groundwater finding its way into sanitary sewer systems, the consequences can range from increased treatment costs to environmental hazards and basement flooding. In Part […]
Investigation Methodology for Determining the Root Cause of Inflow & Infiltration (I&I) – Part 1
Introduction to Investigation Methodology The effective management of inflow and infiltration (I&I) is a critical concern for civil engineers, land developers, and municipalities. Left unchecked, it can stress wastewater systems, increase treatment costs, and lead to flooding and environmental damage. Therefore, implementing a precise, data-driven methodology to identify and quantify I&I is essential. This blog […]

Case Study: Sanitary Maintenance Hole Sealing and Sewer Gas Generation Monitoring, Town of Newmarket
Civica Infrastructure Inc. is a leading consultant in the wastewater management industry specializing in inflow & infiltration (I&I) reduction. Civica was hired by two developer groups to investigate and fix I&I issues within the Town of Newmarket. The goal was to reduce clean rainwater entering the sanitary system and improve sewer system capacity for future […]
Introduction to Sanitary Maintenance Hole Sealing and Approaches
When it comes to maintaining infrastructure, it is important to have a systematic approach to ensure everything runs smoothly. This is especially true for sanitary maintenance hole (MH) sealing. Serious consequences such as leaks and environmental hazards can result when these structures, which play a crucial role in wastewater management systems, are not properly sealed. […]
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, […]
How Can Real-Time Monitoring Effectively Quantify Combined Sewer Overflow and Water Quality?
Adapted from an article written by Alex Ding and Tony Petrucci for Environmental Science & Engineering Magazine The sewer system has an important role in our daily lives. It transports wastewater away from our homes and businesses, treating it for safe disposal. There are two types of sewer systems: sanitary sewers and storm sewers. Sanitary […]
