Flow and Rainfall Monitoring – Ensuring Data Quality and Introduction to Analysis Tools (Part 1)

Sewer Inspection Services

In the first two installments of the Flow Monitoring Webinar Series, Civica aimed to provide a greater understanding of natural phenomena (e.g., rainfall) and assess built systems (infrastructure) and how they perform against design expectations. The webinars also examined available technology and how to effectively operate and maintain it. Now, this third webinar explores the…

Flow and Rainfall Monitoring – Available Technology and How to Effectively Operate and Maintain It (Part 1)

Flow Measurment Tools

Rainfall monitoring is the measurement of rainwater (and potentially snow) accumulation over time. Rainfall monitoring helps municipalities and engineers better understand how much precipitation falls in an area and how it affects water supplies, land use, flooding, and other elements of the environment. Knowing the amount of rainfall enables municipalities to make decisions on topics…

Introduction to Collection System Flow and Rainfall Monitoring (Part 1)

flow and rainfall monitoring

Flow and rainfall monitoring is a crucial aspect of managing water resources in municipalities. Flow and rainfall monitoring involve measuring the natural occurrence of precipitation as well as human-related inputs (i.e., sewage in wastewater systems) and the resulting flow conditions in collection systems. In this blog post, we will delve into the importance of flow…

Stormwater Management Facility Sediment Efficiency Monitoring Using Innovative Forecasting and Sampling Techniques (Part 1)

Flow monitoring

The Ministry of the Environment Conservation and Parks (MECP) has adopted legislation that requires the removal of up to 80% of the total suspended solids (TSS) present in urban stormwater. This is critical to stormwater management. In many urban areas throughout Ontario, this legislation has led to the implementation of different types of stormwater management…

Case Studies for the Identification and Quantification of Sanitary Maintenance Hole Inflow and Infiltration (I&I)

MH water management

Sanitary sewer capacity can be quickly overwhelmed during large rainfall or snowmelt events. Maintenance holes (MH) —even ones not in low-lying areas—can become submerged and produce an inflow of water to sanitary systems. Inflow and infiltration inspections are designed to assess sanitary sewer capacity analysis, giving you a more comprehensive picture of your wastewater asset…

Methodology for the Identification and Quantification of Sanitary Maintenance Hole Inflow and Infiltration (I&I)

field services civica

During heavy rains and snowmelt, streets are designed specifically to channel water into ponding areas. In some circumstances, however, the amount of rainfall can be such that maintenance holes become submerged, exceeding the sanitary sewer capacity and causing floods. An inflow and infiltration inspection can help quantify storm water inflows through submerged maintenance holes, allowing…

Impacts of Existing Storm Drainage Design Standards in Ontario on Sanitary System Capacity (Part 2)

Strom water drainage

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)

Sewer flow monitoring

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…

Challenges of the New Subdivision Flow Monitoring to Assess Performance of Inflow and Infiltration (I/I) Prevention

Sewer Inspection Services

The innovative New Subdivision I/I Prevention Program has yielded great results for multiple municipalities when it comes to infiltration and inflow (I/I) reduction. That said, it doesn’t mean that the new subdivision I/I prevention plan is without its challenges. Let’s take a look at some of those challenges laid out in the flow monitoring plan.…
