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.…

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

Municipal Water Management

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

Sewer Inspection

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…

5 Key Insights into the Environmental Compliance Approval (ECA) Regulations

land development

The Consolidated Linear Infrastructure Environmental Compliance Approval (CLI-ECA) is a new process governed by the Ministry of Environment, Conservation, and Parks. With the new laws and regulations governing land development and infrastructure, it’s important for municipalities and their stakeholders to understand these guidelines and effectively follow them. Below, we outline five key insights into the…

Why Do We Need Stormwater Management Ponds in Ontario?

Stormwater management ponds are designed specifically to collect runoff from the local storm sewer system. A stormwater management pond will temporarily hold this excess water, treat the water to remove pollutants, then release it back into the waterways. Without managing stormwater ponds effectively, floods and other issues could arise, causing havoc and costing the local…
