Predict and prevent flooding in complex urban networks

Urban drainage systems are under growing pressure from climate change, urbanization, and aging infrastructure. Staying ahead of flooding requires more than monitoring—it demands foresight, coordination, and the ability to act decisively before impacts reach communities.

By combining Aquadvanced urban drainage, Optimizer, and the eRIS Data Hub, you gain a connected approach to predicting, preventing, and managing flood risk across even the most complex urban networks.

Flood prevention starts with knowing what’s happening now—and what’s coming next. Aquadvanced urban drainage continuously analyzes network conditions by combining real-time operational data, weather forecasts, and hydraulic behavior to deliver a live, system-wide view of sewer and stormwater performance.

Predictive analytics forecast rainfall impacts, storage availability, and network response hours or days in advance, enabling early warnings for flooding, CSOs, and environmental risks. You can proactively adjust control strategies to maximize available storage and reduce downstream impacts before thresholds are exceeded.

When flood risks emerge, utilities must weigh multiple response options quickly. Optimizer evaluates thousands of possible operational and investment strategies simultaneously—such as inline storage utilization, flow control, inflow management, or offline storage alternatives.

Rather than testing solutions one at a time, you can identify the most effective combination of actions for each scenario, balancing cost, performance, and service outcomes. This optimization-driven approach ensures flood mitigation efforts reduce risk across the entire network, not just in isolated locations.

Reliable flood prediction depends on trusted, connected data. The eRIS Data Hub securely connects operational systems, models, sensors, and external data sources into a single, unified view—breaking down data silos across your organization.

With built-in cybersecurity protections and seamless integration between eRIS and the Aquadvanced suite, you gain faster access to the data needed for real-time control, predictive analytics, and scenario planning. A robust library of connectors widely used across the North American water industry reduces deployment time and accelerates time-to-value, especially for existing eRIS customers.

Together, Aquadvanced urban drainage, Optimizer, and eRIS Data Hub help you unlock hidden capacity within existing assets—often delaying or avoiding costly capital expansion.

This integrated approach supports:

• Optimized use of inline and distributed storage
• Reduced urban flood risk and environmental impacts
• Improved performance during extreme weather events
• Better coordination of operational and planning decisions
• More defensible, data-driven investment strategies

As rainfall patterns become less predictable, you need systems that adapt as conditions change. By combining real-time intelligence from Aquadvanced urban drainage, advanced scenario evaluation with Optimizer, and secure data integration through eRIS Data Hub, you move from reactive response to proactive flood prevention.

The result is a resilient, future-ready approach to urban drainage management—protecting your communities today while preparing for tomorrow’s challenges.

The NYCDEP CSO Optimization Study aimed to reduce combined sewer overflow events by optimizing regulator structures within the sewer system to minimize flooding risks.

Using calibrated hydraulic models integrated with Optimizer software, the study evaluated modifications such as adjusting overflow weirs and underflow sizes to lower CSO frequency, particularly during smaller storms, while preventing upstream backups and surcharge. The results showed that many sewersheds could reduce annual CSO activations by over 15%, contributing to improved flood prevention and system resilience. These findings were incorporated into long-term sewer control plans to enhance urban flood management cost-effectively.
