Solutions
Tetra Tech experts pioneered the development of Csoft, the real-time control (RTC) solution to optimize flows for complex wastewater and stormwater systems. For more than 25 years, Csoft has been successfully implemented in communities in Canada, United States, and France.
Csoft integrates continuous system monitoring, weather forecasting, real-time digital twins with hydrological and hydraulic models, and advanced data analytics to optimize system-wide operations. It also enables improved flow routing, optimized filling and dewatering of storage basins and tunnels, and maximized treatment capacity utilization, providing utilities with the digital technologies needed to improve operations and efficiency.
Real-Time System Intelligence
- Integrates model-based digital twins with validated monitoring sensors and online calibration to represent complex real-world hydraulics
- Enables proactive monitoring and visualization of rainfall progression, system responses, and system performances
- Provides safe and reliable operation for complex sewer and drainage systems
Advanced Operational Control
- Efficiently controls and reduces sewer overflows while respecting system constraints and adapting to changing conditions
- Calculates and updates the optimal operating set points for independent facilities every five minutes based on actual field conditions and flow predictions
- Prioritizes the protection of environmentally sensitive areas or critical assets while balancing inflows to the wastewater treatment plant with quick reaction times
Operator Support and System Optimization
- Manages control facilities automatically and incorporates real-time control, from local reactive control to coordinated regional control to system-wide control with prediction
- Builds operator confidence through manual override, easy set point or control strategy modification, and customized visualization for decision support and performance tracking
- Maximizes return on investment in monitoring, data, and system expansion through centralized intelligent control and proactive operation
