Combined Sewer Overflow (CSO)
What’s your stormwater issue?
Combined Sewer Overflow (CSOs)
Mother Nature’s increasing volatility means “100-year” storm events are occurring much more frequently. This coupled with seasonal melt adds increasing pressure on water infrastructure and can lead to intense flooding and increased Combined Sewer Overflow (CSO) events.
We’ll walk you through the four critical steps of modeling, triple bottom line analysis, funding, and design to help your community mitigate CSOs.

Reporting accurate and meaningful CSO data has long been a challenge. Metering information is only as good as the quality of data.
Predictive analytics—based on historic data—can better position municipalities when it comes to these increased near real-time reporting. Stantec’s OpsGenie works with a municipality’s existing asset management tools to compile all data relevant to operations and maintenance in a web-based platform.
We have developed tools to analyze your rate structures, model the financial impacts of your infrastructure improvements, and even connect you with possible funding sources for your project.
Once stormwater is captured in a tunnel, pump stations push the water to nearby treatment facilities eliminating the chance of discharge into the surrounding environment.
The Easterly Tunnel Dewatering Pump Station project is one of the largest CSO pump station projects in the US and a critical component of the overall stormwater program.
Once a municipal system is overwhelmed by stormwater, there are two options – backing up into homes and businesses or overflowing into nearby bodies of water. Neither are good options. A project like our Ottawa CSST is a solution to important CSO control.
Flooding does physical and economic harm to any community.
Keeping our waterways clean is more important now than ever.
Landscape solutions are often environmentally and economically healthier.
Meeting regulations can be complicated and expensive, we can help.
Heavy precipitation events and sea level rise are our new normal.

Flooding is a natural hazard causing extraordinary social and economic impact – from loss of life, property damage, and harm to the economic well-being of any community.
We’ll walk you through the four critical steps of modeling, triple bottom line analysis, funding, and design to help your community minimize the impacts of flooding.
Modeling is an important first step to address and identify commonalities and differences in the causes and impacts flooding challenges had and could have on a given municipality.
Through the power of visualization technology (using a tool frequently used for video game development known as Unreal Engine) and the integration of FEMA Risk MAP data, virtual walk throughs of neighborhoods to see anticipated effects of a flood event on property, business, and community are a reality.
At nearly a mile long and the ability to capture 2,300 cubic feet of water per second, or 820,000 gallons per minute, the Albany Park Stormwater Diversion Tunnel is helping this Chicago neighborhood better weather the storm after years of chronic flooding issues and destruction.
By choosing how and where to let the water run—as if selecting spots during an acupuncture treatment—we can relieve roads, streets, and basements of their current flooding pressures.

Forget about paving—lead with landscape. Sustainable water management practices like incorporating green infrastructure to capture and even treat stormwater are not only environmentally, but economically-healthier.
We’ll walk you through the four critical steps of modeling, triple bottom line analysis, funding, and design to help your community benefit from green infrastructure.
Accurately modeling is key to identifying potential problems – how stormwater will impact the people, property, and natural resources of the area – before they become catastrophes. Modeling tools are used to understand and evaluate these complex processes involving stormwater runoff.
The Green City, Clean Waters Program is Philadelphia’s 25-year plan for the control of combined sewer overflows and protect and enhance the health of Philadelphia’s waterways through investments in green stormwater infrastructure. The key to the program is a block-by-block approach in which each project is essentially treated like a pilot – monitored and tested at every turn to determine how it’s working.
This is the largest such program ever envisioned in the U.S. with a total investment of approximately $2.4 billion dollars. It’s broken into three fronts: water, land, and infrastructure.
By taking a holistic look at your stormwater management system and developing an integrated philosophy using water’s footprint as your guide you can substantially reduce flooding, increase water quality, add valuable community space, connect neighborhoods, and stimulate private sector investment and redevelopment.
See how New Orleans is learning to live with water by treating water as a valuable resource and not a nuisance.

Government regulations are designed to protect a community from potential negative impacts of stormwater runoff, from fish kills to polluted drinking water supplies. Understanding what regulations apply and the optimal path to compliance is critical in helping communities effectively allocate their limited budgets.
We’ll walk you through the four critical steps of modeling, triple bottom line analysis, funding, and design to help your community meet regulatory requirements.
As stormwater pollution continues to grow, we’ve been working with our clients and the Stormwater Testing and Evaluation for Products and Practices (STEPP) group to establish a common framework for testing and evaluating both public domain and proprietary stormwater control measures.
Dynamic water modeling allows for infrastructure to be optimized when applied to storage challenges. This can mean the difference between compliance and catastrophe. See how we helped the Narragansett Bay Commission “sweat the system” to meet CSO control criteria without introducing any additional risk.
We led VDOT’s MS4 permit program by implementing a comprehensive Stormwater Management Program to reduce the contamination of stormwater runoff and prohibit illicit discharges. Not only did we help write the regulations, we designed the infrastructure to comply.

The costs and impacts of urban flooding are growing more severe as development and population growth continues in urban areas, and as sea level rises and heavy precipitation events become more frequent due to climate change.
We’ll walk you through the four critical steps of modeling, triple bottom line analysis, funding, and design to help your community be more resilient to climate change.
A fundamental challenge is not the quality of data, but stakeholders’ understanding and access to credible, actionable information.
Our vulnerability and risk assessment team organizes the data, identifies climate change impacts on assets, and delivers risk profiles and evaluations to prioritize actions for our clients to adapt.
The 2013 Southern Alberta flood was one of the most devastating and costliest natural disasters in Canadian history.
Diverting water can help mitigate future flooding issues. One of those mitigation strategies is the Springbank Off-stream Storage Project (SR1). SR1 will temporarily divert up to 594 cubic meters per second of water from the Elbow River to an off-stream storage reservoir during extreme flood conditions and later release the excess water back into the river after the flood peak has passed.
Our Climate Change Risk Assessment team helps clients be well informed and prepared for a future of uncertainty. Whether for roadways, buildings, or water supply systems, we produce assessments that help your infrastructure best adapt to the challenges of climate change. Prioritize your actions, be ready for funding opportunities, and create resilient projects with Stantec.
To better protect communities, we must improve the understanding of flood risk among all stakeholders
