  1. The Vannet Group, LLCSCADA Made Simple SCADA Monitoring

  2. SCADA Made Simple

  3. SCADA Made Simple • What is SCADA? History of SCADA • Various types of SCADA systems • Differences between systems • Why the need for monitoring? • How SCADA applies to Water and Wastewater • The Mission monitoring RTU • Questions and Answers

  4. WHO Am I? • Environmental Health Specialist (US ARMY) • Private Industry Perdue Farms, Inc • Small Town WATER and WASTEWATER Operator • State Water System Inspector • State Capacity Development Coordinator • EPA- Small Systems TA Grants and Small System Tool Development; Capacity Dev Coordinator, Co-lead on Op Cert Program, and all around nice guy. • (PS- Check’s in the mail)

  5. Importance of Communication Ability to exchange ideas/desires/needs Express yourself Send a message Tower of Babel (Bible)

  6. Communication- Imperative

  7. What is SCADA? • SCADA systems were first used in the 1960’s • The acronym SCADA means supervisory control and data acquisition • SCADA systems are used to monitor and control plant or equipment in industries such as: • Telecommunications • Energy, oil and gas refining • Transportation • Water and Wastewater monitoring and control

  8. Concept: monitors input signals from a process manages the data produces output signals that influence the process.

  9. Old School Communications

  10. Sampling Points

  11. Pre-SCADA: Telecommunication & Miss Jenkins

  12. 4 VOLUNTEERS

  13. Physical Components • Remote data monitoring units, • Communications platform and a • Central host or master that manages • entire system.

  14. First Generation SCADA

  15. 2nd Generation

  16. 3rd Generation

  17. What is SCADA cont. • SCADA systems can be relatively simple, such as ones that monitor environmental conditions of a small office building, or very complex, such as systems that monitor the activity in a nuclear power plant or control a municipality’s water system through tank, pump, and well control.

  18. What is SCADA cont. • SCADA systems gather information such as: • Pump RuntimesFlow • Water LevelsPressure • AmperageTemperature • …and transfers and stores the information back to a central site (computer).

  19. What is SCADA cont. SCADA systems can monitor specific alarm setups such as: • High or Low Level • Pump Failure • Intrusion • Power Loss • Generator Running • Phase Loss • High Temperature • Excess Pump Starts • Analog Thresholds

  20. Types of SystemsUsed in our industry • Auto Dialers • Private Radio • Wireless Data Network Based

  21. Differences Between Systems • Method of transmitting data • How often the data is transmitted • Amount of data transmitted • Cost!!!

  22. Auto Dialers • Good solution for basic alarms • Need a dedicated phone line • Limited RTU mobility if you want to move it • You have to deal with the phone company! • Limited features and functionality

  23. Private Radio • Optimal for advanced applications, i.e. oil, gas and storage plants • High number of inputs and outputs • Generally custom designed • Single database computer (control center) • Costly software • Setup is time-consuming • On going maintenance costs

  24. National Wireless Data Network System The Newer Technology Options • Uses the public cellular network system • Low equipment and installation costs • No costly software • Internet based access • Mixed deployment/Roll out over time

  25. National Wireless Data Network System • Ease of installation • Scalable from 1 unit to X units • Compatible to existing HMI SCADA software programming mods • Capable of meeting or exceeding homeland security and AWWA standards with 128-bit encryption

  26. Is Cellular Reliable? The short answer is…YES! • Uses the data channel, not the voice • Each transmission is confirmed end to end • All transmissions are encrypted • After disasters, cell towers are brought in on tractor trailers and communication is restored

  27. Internet Basic Components of Internet Enabled Monitoring & SCADA Systems Alarms & Data 4. 3. • Pagers • Fax • Email • Cell Phones Centralized Web Based Software • Field RTU…The Box • National Wireless Data Networks • Centralized Web Software • Alarms To Virtually Anything • Secure Customer Web Site 1. Customer Website 2. 5. RTU Network Carriers

  28. Why the need?

  29. Why the need? • Ever increasing regulatory restrictions are being imposed on Water and Wastewater operators for efficient & safe system operations such as Class 1 Reliability (EPA, DEQ, etc) • Both current & historical data from electronic databases greatly simplify the regulatory reporting process • Redundancy to larger SCADA systems all ready in place

  30. The tank does that all the time. It’s OK.

  31. Applications National Public Wireless Data Networks combined with Internet Data Access are now a permanent contender for automation in the Water & Wastewater Industry.

  32. How It Applies to Water/Wastewater • Wireless Technology Can Be Applied In A Variety of Remote Applications • Water Pumping Stations • Sewer Lift Stations • Level / Flow / Pressure Applications • Tank Storage Applications • Storm Water / Sewer Flow Applications • Meter Reading Applications • Water Well and Tank Control • Rainfall Monitoring

  33. How It Applies to Water/Wastewater cont • Profiling and understanding: • Flow Data  Rainfall Data • Level Data  Surcharge Data • Pump Activity  Other Parameters …is crucial for effective operations. • New wireless technologies are now available for very remote sites.

  34. Typical Lift Station Rainfall Monitoring

  35. Water Tower Monitoring

  36. Water Plant Monitoring • Tank and Well Control

  37. Very Remote Location? Solar Power is the Answer!

  38. Map location of your stations

  39. Example Supplier Sell Points • Reliable – Money Saving Features • Prepackaged – Ease of Installation • Simple – Very Affordable • M110 Full Monitoring System • M800 Full SCADA • M200 Solar Station • M81 CSO/SSO Monitoring INCLUDES: Secure Website, Graphics & Software, Alarms, Mgmt. Reports, Runtime Reports, Maintenance Logs

  40. Bt wut r t costs? Data Loggers with modems costs on the order of $1,100 to $1,800 A small SCADA system cost on the order of $1,400 to $4,600
