Real-Time Optimization of Stormwater Infrastructure Using Continuous Monitoring and Adaptive Control


Conor Lewellyn, P.E., C.F.M.

Kaitlin Vacca, Ph. D., P.E.




Over the past several years, a new approach to managing stormwater has emerged as a viable alternative to traditional, passively controlled, stormwater management facilities. Known as Continuous Monitoring and Adaptive Control (CMAC), this approach can optimize a stormwater facility for one or multiple objectives and be adapted over time as regulations, land-use, and/or climate changes. CMAC solutions integrate information directly from field deployed sensors with real-time weather forecast data (i.e., NOAA forecasts) to directly monitor performance and make automated and predictive control decisions to actively manage stormwater storage and flows. CMAC solutions have been shown to result in significant increases in the performance of a range of existing stormwater best management practices while reducing operational and outcome risk.


The CMAC approach can improve environmental outcomes in several ways, including:

     Improving water quality from facilities by increasing residence time and/or improving unit process effectiveness (e.g., settling, denitrification).

     Restoring pre-development hydrology and base flows by actively modulating release rates based on forecast information.

     Increasing the volume retained on site for water reuse.

     Intelligently detaining flows in combined sewer systems for release during dry weather.

     Reduce the frequency of flooding events.

     Being adaptable to future climatic conditions or changes in site characteristics by re-configuring the software.

CMAC technology has been used to meet water quality, flood control, hydromodification, and water reuse objectives at over 130 sites across 21 US states. This presentation will first provide an overview of CMAC technology, will showcase several CMAC projects, and will highlight performance during wet weather.


Speaker Bio:  

Conor Lewellyn is a Senior Applications Engineer at OptiRTC as well as a PhD candidate at Villanova University. He received a B.S. degree from the University of Maryland in Civil and Environmental Engineering and a M.S. degree from Villanova University in Civil Engineering. He has approximately 8 years of experience in water resources engineering consulting focusing on the planning and design of stormwater management and green infrastructure systems. His current work and research involves the design, implementation, and evaluation of performance of real-time control stormwater management and green infrastructure facilities. 

Kaitlin Vacca is a water resources engineer with a unique background overlapping in both the built and natural environments. Dr. Vacca is a Philadelphia-based Senior Project Manager at OptiRTC with projects in Philadelphia as well as Howard, Montgomery, and Anne Arundel Counties in Maryland. She received a B.S. degree from Northeastern University in Civil and Environmental Engineering, a M.S. degree from Penn State University in Architectural Engineering, and a Ph.D. from Villanova University in Civil and Environmental Engineering. Dr. Vacca has designed green infrastructure in Philadelphia, Maryland, and Washington D.C. and currently focuses on implementing stormwater management using real-time controls. With 10 years of combined research and practical experience within environmental, architectural, and water resources engineering, Dr. Vacca provides a diverse perspective on sustainable design practices. 


This seminar does qualify for 1.0 Professional Development Hour (PDH). A Certificate of Attendance will be available on site for AWRA-PMAS members only. The meeting price for non-members who wish to receive a Certificate of Attendance for the PDH is $10.00 ($3.00 for meeting + $7.00 for certificate).  

Please note: all lunch orders will close by noon on the day before the presentation. In addition, all lunch orders will need to be paid for online by this time. We are unable to refund the cost of lunch or meeting fees because they are paid ahead of time based on number of registrations. Registration begins at 11:30am with the presentation starting promptly at 12:00pm.

Thank you!
