Distributed Control 4 “A design approach in which factory or machine control is divided into several sub-systems, each managed independently by a unique programmable controller or other control system, yet all interconnected to form a single entity. Individual subsystems may be interconnected via communications networks. ” » Patrick-Turner Industrial Automation Dictionary, 1996
Distributed Control System Advantages 4 4 4 4 Fault tolerant controllers Redundant input/output card capabilities Redundant communications Advanced control configuration Integrated human machine interface Industry domain expertise Program control security
Programmable Controller 4 “A solid state industrial control device, member of the computer family, designed specifically to be programmed to perform relay logic functions, timing, counting, arithmetic, and data manipulation, all for the purpose of implementing control over industrial machines and processes. The programmable controller consists of a central processor, memory system, input/output system, and power supply, all of which are designed to operate in harsh industrial environments. ” » Patrick-Turner Industrial Automation Dictionary, 1996

Homeland Security for Drinking Water Supplies 4 Three Areas – Increased physical security surrounding water supply systems – Redundancy design in the system – Source water protection and monitoring
“Homeland Security for Drinking Water Supplies” 4 The most expedient and potentially less costly actions for protecting a water supply system consist of installing or enhancing a physical security system, including fences, exterior and interior sensors, alarm assessment and communication and entry control. The risk of cyber threat can be reduced by increasing security in the Supervisory Control and Data Acquisition (SCADA) System used for utility monitoring and operation and remote communication. SCADA security can be tightened by either hardware or software enhancements by IT professionals. » Marcia Greenblatt, Ph. D. , Jack Donohue, and Ken Wagner Ph. D. Courtesy of ENSR International 4 Translation: Control system design consideration other than adequacy of meeting control needs.
“Homeland Security for Drinking Water Supplies” 4 Source water protection and early warning monitoring systems could alert operators of any change in water quality in sufficient time to prevent contamination and disruption of the public water supply. Early water monitoring requires a long-term baseline of water quality data to understand typical parameter ranges. When observed water quality parameters are outside expected values, warning signals can be transmitted, increased sampling and testing can be conducted, and the system operation adjusted appropriately. In addition to a well designed monitoring system, an inventory of system hydrology (including reservoir residence times, dilution rates, flow-stage relationships, etc. ) will allow for rapid assessment and decision making in the event of contamination. » Marcia Greenblatt, Ph. D. , Jack Donohue, and Ken Wagner Ph. D. Courtesy of ENSR International 4 Translation: You cannot control what you cannot measure!!
Simple solutions for security 4 Prepare (or update) an emergency response plan. Make sure all employees help to create it and receive training on the plan 4 Post updates emergency 24 -hour numbers at your facilities in highly visible areas (pump house door, vehicles, office) and give them to key personnel and local response officials 4 Get to know your local police and ask them to add your facilities to their routine rounds. Practice emergency response and public health officials 4 Fence and lock your drinking water facilities and vulnerable areas (e. g. wellhead, hydrants, manholes, pump house, and storage tanks) 4 Lock all entry gates and doors and set alarms to indicate illegal entry. Do not leave keys in equipment or vehicles at any time 4 Install good lighting around your pump house, treatment facility and parking lot 4 Identify existing and alternate water supplies and maximize use of back flow prevention devices and interconnections 4 Use your Source Water Assessment information to work with any businesses and homeowners that are listed as potential sources of contamination and lesson their threat to your sources 4 Lock monitoring wells to prevent vandals or terrorists from pouring contaminants directly into ground water near your source. Prevent pouring or siphoning contaminants through vent pipes by moving them inside the pump house or treatment plants, or if that isn't possible, fencing or screening them 4 In case of an emergency, first call "911", then follow your emergency response plan – From: EPA New England Office
