Big Data, Little Water Making “Green” Work Smarter and Harder

Eric W. Strecker, P.E., B.C.E.E Geosyntec Consultants Portland Oregon Big Data, Big Cloud, and Little or Lots of Water • Passive control of water resource systems is limited in effectiveness • The ability to use data from the Cloud/ together with local data to control a valve can greatly increase the effectiveness of water resources systems for: • Flood control and management • Water quality protection • Stream erosion (Hydromodification) reduction • Water supply augmentation • Technology is cheap (vs. building or enlarging a “HIG” -hole in the ground- or above ground tank) Challenges with Green Infrastructure for Solving Big Issues

• Green is full when the big storm comes • Therefore, Flood control, CSO control, hydromodification control, etc. is difficult for Green Infrastructure • Rainwater harvesting and wet weather management can have competing goals when system are passively managed EPA Headquarters'- Harvest and Use Cistern

• Visited on April 28th, 2009 (about 80 degrees that day) • Cisterns were empty as flows were being bypassed due to lack of irrigation demand EPA Headquarters'- Harvest and Use Cistern

• 6 Tanks store about 1” of rainfall from roof • About 9 to 10 days to drain the tanks when full • Likely that significant amount of runoff bypasses the tank when tanks on-line What is it? What is It?

• Summary: OptiRTC is a cloud-based suite of computing services that together with local instrumentation provides automated real-time control, data acquisition and data management solutions for a wide range of civil and environmental engineering applications. Basic Solution Capabilities

• Distributed real-time monitoring of civil and environmental infrastructure sensors • Hardware-”agnostic” • Seamless integration of Internet-available data (e.g., NOAA, USGS), local gage/ sensor and manually entered data (e.g., field forms) • System modeling and control algorithms • “Real-Time Consulting” • Web-based data visualization • Available from any Internet-connected device; no proprietary software • Automated and remote control capabilities • Control decisions based on algorithms and/or user input • Hardware and software solutions easily scale • One site to millions (Big Data) of monitoring and control points worldwide System Overview Web Dashboards
