The CMAC At-Scale Initiative

ANNOUNCEMENT: Participants Selected for Continuous Monitoring and Adaptive Control At Scale Initiative

Press Release: Opti and Clackamas County Announce Partnership for Watershed Protection

Applications are now closed, and accepted participants have been notified. If you would like to learn about additional opportunities to work with Opti, please contact us at

The CMAC At-Scale Initiative is a unique partnership opportunity to experience the at-scale benefits of continuous monitoring and adaptive control (CMAC) of stormwater infrastructure. Through a 50% in-kind funding contribution for CMAC retrofits, participants will improve the effective capacity of their existing stormwater infrastructure while contributing to a significant research effort.

Through this program, Opti seeks to evaluate the potential exponential benefits of its dynamic control systems at scale. Recent advances such as Opti’s CMAC solution, OptiNimbus, are providing the foundation for a future of “always-on,” digitally-connected stormwater infrastructure. Intelligent, dynamic management of such infrastructure promises to dramatically improve the way we control our urban environments and impact natural systems. These solutions are particularly well suited for situations where timing, duration, peak control, volume reduction, use and reuse, and water quality are critically important.

For more information, we invite you to watch a recording of the January 21 informational webinar below.

How It Works

1. Participants apply for the program and work with Opti to identify stormwater sites that will receive hardware, data services, and site commissioning at a 50% reduced cost (typically $5-8k per site)

2. Simple retrofits connect your ponds, tanks, and other stormwater storage sites to CMAC technology for a 6-month period, free of long-term commitment

3. Rainfall forecast-based adaptive controls optimize your infrastructure to meet individual site objectives with improved site and watershed -scale performance and data visibility

4. Final reports document individual and program-wide performance of CMAC retrofits and provide invaluable insight for future projects

Application & More Information

CMAC At Scale generated a widespread and positive response in its initial stages, with applications submitted by watersheds and communities across the country. The accepted applicants submitted at least three stormwater management facilities for retrofit with CMAC technology, with some requesting installation at up to twelve facilities. Adaptive forecast-based control is anticipated to be fully deployed under this program at 30+ sites for a six-month study period beginning September 30, 2016.
