Continuous monitoring and adaptive control—the internet of things transforms stormwater management

Abstract | Both traditional (gray) and green stormwater management practices have almost entirely been designed as passive systems governed by a fixed control structure to achieve a target water quality and/or quantity objective (i.e., treatment volume, attenuation). Passive systems, however, rarely represent optimal solutions. Advances in low-cost, Internet-accessible controller systems and wired and wireless communications have made real-time and dynamic controls of distributed stormwater facilities now viable, cost-effective options for new construction as well as retrofits. The physical setup of continuous monitoring and adaptive control (CMAC) stormwater systems includes three primary components: a water level sensor to provide data on the facility’s current state, an actuated valve to control its hydraulics (typically outflow), and an Internet connection most often provided in remote locations by cellular data. Figure 2. A schematic of CMAC for green and gray infrastructure; field-deployed sensors and Internet connectability CMAC facilities have been deployed throughout the United States to enhance underperforming facilities provide the ability to verify and improve the performance of distributed stormwater infrastructure and optimize designs for multiple objectives, such as flood protection, water quality treatment, water reuse this assumption as it relates to water resources objectives, such as water-quality treatment and and channel protection.

Detecting overflows with a mix of old and new technologies

Abstract | In 2013, the Boston Water and Sewer Commission (Commission) initiated a pilot study of 10 combined sewer overflow (CSO) structures to determine if current technology is reliable enough to measure overflow activation, duration and volume with confidence for public notification on the Commission’s web site. A hydraulic model is being used for regulatory reporting for volume, but a more immediate system is needed for public notification. This paper describes an innovative method for understanding the regulator behavior and learning how to identify overflows by looking for repeatable patterns in plots of depths and velocities. The incoming and overflow lines in all the regulators were monitored with depth and velocity sensors. Plots of these depths and velocities, or scattergraphs, revealed patterns used to identify when overflows began and ended. Figure 2.

The presumed cause of this clockwise pattern is that the interceptor has more capacity during the first part of the storm, and is surcharged or affected by downstream pump activity during the recovery period, allowing less flow to enter. This has not been verified by any metering data. A second example is a scattergraph from an event that just overtopped the weir with no downstream tidal influence. There is a telltale data pattern from a meter just upstream of a weir in this condition, and it is a near-linear pattern as shown in Figure 4. Figure 5 is a scattergraph of the incoming meter, and it shows the beginning of this linear pattern for just three data points that exceeded the weir height Figure 4.
