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
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)

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
Concept: monitors input signals from a process manages the data produces output signals that influence the process.
Physical Components • Remote data monitoring units, • Communications platform and a • Central host or master that manages • entire system.
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.
What is SCADA cont. • SCADA systems gather information such as: • Pump RuntimesFlow • Water LevelsPressure • AmperageTemperature • …and transfers and stores the information back to a central site (computer).
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
Types of SystemsUsed in our industry • Auto Dialers • Private Radio • Wireless Data Network Based
Differences Between Systems • Method of transmitting data • How often the data is transmitted • Amount of data transmitted • Cost!!!
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
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
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
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
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
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
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
Applications National Public Wireless Data Networks combined with Internet Data Access are now a permanent contender for automation in the Water & Wastewater Industry.
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
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.
Typical Lift Station Rainfall Monitoring
Water Plant Monitoring • Tank and Well Control
Very Remote Location? Solar Power is the Answer!
