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…

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 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…

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…
