The application of conventional real-time and dynamic control and feedback systems is commonplace in industrial settings, water supply and treatment, wastewater treatment and conveyance, and Combined Sewer System management; however the use of automated and manually controlled onsite control systems in sustainable stormwater management has been quite limited.
New approaches and recent advances in information technology infrastructure as well as hardware systems and software solutions are delivering the necessary underlying foundations of a future of ubiquitous, digitally-connected, green infrastructure that will change the means and methods by which we understand and control our urban environments and impact natural systems. The availability of a new breed of robust, low cost, highly functional, internet accessible, programmable logic controller systems coupled with the ease of wired and wireless communications are making onsite real-time and dynamic controls viable options for both new construction as well as retrofits with green infrastructure based stormwater systems.
Typical stormwater analysis and modeling and most of current effort in the field of stormwater engineering is focused on analyzing and developing designs that passively achieve target goals (e.g., peak attenuation, volume reduction, water balance, pollutant removal targets, etc.); however, passive systems rarely represent optimal solutions. Dynamic systems are particularly well suited for complex situations where timing, duration, peaking control, volume reduction, use and reuse, and water quality are critically important.
Focused research on distributed real-time control under funding from the Water Environment Research Foundation is developing new directions in applications, design, and equipment that incorporate the most recent advances in hardware and software. The inclusion of dynamic control systems in onsite stormwater systems and as integral components of holistic water management is proving to be one of the more effective tools engineers and scientists will have at their disposal in the coming years for meeting increasingly complex environmental goals.
The system architecture and operation will be presented to demonstrate seamless integration of internet based information streams (e.g., stage sensors, weather forecasts, stream gauges, tides, other online monitoring networks) into on-board and server-side decisions allowing control of a wide variety of urban green infrastructure components. In addition, the presentation will provide several real case studies where data are available to demonstrate performance.
