This poster presentation highlights the critical role of the environmental engineer in addressing urban sustainability challenges within the specific context of Montreal, Canada. As one of North America's largest metropolitan areas, Montreal faces unique hydrological and climatic pressures due to its location on an island within the Saint Lawrence River. This study explores integrated approaches to stormwater management combined sewage overflows (CSOs) mitigation, and green infrastructure implementation. The primary objective is to demonstrate how modern environmental engineering principles can be adapted to preserve the ecological integrity of the St. Lawrence ecosystem while supporting urban growth.

Montreal, Quebec, stands as a cultural and economic hub in Canada. However, its dense urban infrastructure poses significant environmental engineering challenges. The city’s combined sewer system, a relic of 19th-century planning, often struggles during heavy precipitation events common in the spring and autumn seasons. When rainfall exceeds the capacity of the treatment plants or pipe networks untreated wastewater bypasses treatment facilities and discharges directly into natural water bodies.

This phenomenon not only violates environmental regulations but also threatens public health and biodiversity. The role of the modern Environmental Engineer extends beyond mere compliance; it involves designing resilient systems that adapt to changing climate patterns. In Montreal, where freezing temperatures in winter complicate infrastructure maintenance and operation, engineering solutions must be robust and year-round effective.

This research utilizes a multi-faceted approach combining hydrological modeling, field data analysis, and pilot-scale testing of green infrastructure technologies. The methodology is divided into three core phases:

1. Data Collection & Baseline Analysis: Historical precipitation data from Meteorological Service of Canada was analyzed to identify trends in extreme weather events affecting Montreal. Current performance metrics of the Metropolitan Sanitary Sewerage System (SMCS) were reviewed to quantify CSO frequency and volume.
2. HYDROLOGIC MODELING: The Storm Water Management Model (SWMM) was calibrated to simulate the behavior of current infrastructure versus proposed green interventions. Scenarios included low, medium, and high-intensity rainfall events typical of the Montreal climate zone.
3. Pilot Implementation & Monitoring: Three pilot sites were selected in densely populated boroughs such as Rosemont–La Petite-Patrie and Mercier–Hochelaga-Maisonneuve. These sites featured permeable pavements, bioswales, and rain gardens. Water quality parameters (total suspended solids, nitrates, phosphates) were monitored over a 12-month period to assess treatment efficiency.

The Canadian context, specifically the Montreal urban environment, presents distinct hurdles for environmental engineering professionals:

• Freeze-Thaw Cycles: Infrastructure must withstand extreme temperature fluctuations. Porous materials used in green infrastructure can suffer structural damage if water trapped within pores freezes and expands. Engineers must select materials with high frost resistance.
• Snow Management Interference: In winter, snow plowing operations can clog bioswales and permeable pavements with sand and debris removed from roads. Engineering designs must incorporate easily maintainable access points for municipal services.
• Aging Infrastructure Integration: Retrofitting modern sustainable systems into older neighborhoods requires careful coordination to avoid disrupting existing utilities. The Environmental Engineer must act as a project manager, coordinating between civil engineers, urban planners, and environmental scientists.

The preliminary results indicate that green infrastructure can reduce stormwater runoff volume by approximately 30-45% during moderate rain events. Furthermore, water quality improvements were significant, with a 60% reduction in total suspended solids compared to conventional gray infrastructure control points.

Climatic Adaptation: The study confirmed that vegetation selection is critical for Montreal’s climate. Native species such as *Carex* (sedges) and willows demonstrated higher survival rates and pollutant uptake efficiency than non-native ornamentals. This underscores the importance of site-specific ecological engineering.

Social Acceptance: Community engagement proved vital. Public workshops in Montreal neighborhoods revealed that residents were highly supportive of green infrastructure, provided that aesthetic standards were maintained and safety concerns (e.g., mosquito breeding) were addressed through proper design.

The findings suggest a need for updated municipal bylaws in Montreal and across similar Canadian cities. Current regulations often prioritize volume reduction but may underemphasize water quality protection during freeze-thaw periods. Environmental engineers advocate for:

• Mandatory integration of green infrastructure in all new developments over 5,000 square meters.
• Incentive programs for homeowners to install rain barrels and permeable driveways.
• Funding for continuous monitoring and maintenance of public green spaces to ensure long-term functionality.

The Environmental Engineer plays a pivotal role in shaping the sustainable future of Montreal. By combining rigorous scientific modeling with practical, climate-resilient design, we can mitigate the impacts of urbanization on local water resources. This poster presentation emphasizes that successful environmental engineering in Canada requires not only technical expertise but also an understanding of local climatic conditions and community needs. As Montreal continues to grow, collaborative efforts between engineers, policymakers, and citizens will be essential to maintain the ecological health of the St. Lawrence River region.
