We have consulted extensively with our users, reviewed measures they have put in place over the years and discussed their latest plans.Many of them have a vision of an ideal monitoring system that is networked throughout their entire operation. The system would provide constant monitoring of all vulnerable areas. It would immediately report any security breaches or abnormal operating conditions.

It would eliminate any necessity for regular patrols and drastically reduce the frequency of visits to remote sites.The system would be tolerant of efforts to defeat it. It would continue operating if the power were cut off or a communication line severed.

It would be accessible to operations people even if the control room were disabled or evacuated. It would provide security from hacking.The system also would be able to automatically react to conditions and perform control actions, which could safely shut down processes or isolate sections of the water distribution system.You probably realize this is really not a futuristic vision or even a description of an emerging technology.

The fact is the technology for such a system is nothing new. Many of them are in operation, today, throughout the water industry. You probably have one, as well. It's your SCADA system.A BRIEF OVERVIEWThe acronym tells it all.

"SCADA" stands for "supervisory control and data acquisition." The SCADA system is essentially a distributed computer system that is used by operations and management for process monitoring and automation.As shown in Figure 1, the SCADA communication network is spread throughout the water distribution system. Workstations, which are typically PC-based and located in a control room at a treatment plant, allow operators to view the entire process and perWater systems are becoming crucial in today's growing India's infrastructure.

These systems typically requires monitoring and control to balance between demand v/s resources. The ULB/Water supply boards and their executives has tremendous pressure to operate the water supply to its maximum output with proper monitoring of cost. Therefore an independent system to operate this with full transparency is need of the day.

The requirement is for measurement, automation and teleprocessing to bring the monitoring at central place as these systems are spread over very large geographical area.

The interconnect system would automatically allow water from Trenton to flow to Amalga and vice versa, allowing the two towns to share water during emergency situations. To accomplish this, the towns worked with JUB Engineers of Logan, who contracted with Intermountain Environmental (IEI), also of Logan, to install a scada system for water supply control and data-acquisition (SCADA) system to allow each town to view the status of their water system and control the interconnect system as needed.Each town has separate water sources, pump tanks, and distribution systems, so the challenge was to connect them in a way that would easily allow sharing of water.

Intermountain Environmental used the CR1000 Measurement and Control System (manufactured by Campbell Scientific) and VTScada software (by Trihedral) as the foundation for the SCADA system. The outcome was independent systems in each town.The systems connect with numerous sensors via a Campbell multiplexer to monitor parameters such as flow and pressure from water sources into tanks, flow and pressure from tanks into the towns, tank level, and flood conditions at the building housing the system.

The CR1000 uses a Campbell SDM-CD8S dc device controller to control pumps and valves, with each town controlling the valves to allow or disallow the water flowing to the other.VTScada allows the town water managers to view the status of pumps, water levels, and door and hatch alarms. The software can send out alarms, and allows users to access their system information and control devices over the Internet as if they were sitting at the main PC at the town hall.Each town received similar equipment and the systems are independent of each other.

The CR1000 was used as a remote terminal unit (RTU) at each site and also as the programmable logic controller (PLC) at each base station. The dataloggers communicate with each other using Campbell�s RF450 spread-spectrum radio. At each town hall there is a master station that consists of a CR1000 and an NL120 Ethernet interface.

LoggerNet and VTScada run on Windows 7 PCs and communicate with the CR1000 master unit over Ethernet connections.The system has been in operation since May of 2011.

Water purchased from the San Diego County Water Authority is distributed to businesses and residences. Delivery of the potable water requires little to no pumping, as the water travels via a gravity feed from large storage tanks.Carlsbad�s SCADA system has been configured to control various equipment and monitor the water throughout this entire process. Analog and digital input and output modules connect to:� Level transducers that track water levels in large reservoirs and tanks.� Pressure transducers in pipes that measure pressure in pounds per square inch (psi) within each zone and ensure that water is pumped and is flowing efficiently as it�s being delivered.� Flowmeters that measure how many gallons of water per minute are being delivered.� Pressure-sustaining, pressure-reducing, and other valves that open and close incrementally to adjust the rate at which the water flows.

[Native Advertisement]Technician Tom Pagakis oversees the SCADA systems that monitor and control all water and reclaimed water for the city. The key components for these systems are SNAP-brand controllers manufactured by Temecula, CA-based Opto 22.The City of Carlsbad SCADA system monitors transport, and distribution of purchased water from lakes and reservoirs to the city; and reclamation of treated water.�We started using Opto as an experiment,� Pagakis said.

�Years ago, we were using outdated technologies like tone telemetry and later, a mix of I/O modules and systems from other vendors. Special drivers had to be created to make everything communicate and it had become very complicated and unwieldy.�The SNAP systems � which communicate with each other and back to the control center through a combination of radio, serial, and Ethernet links � are used to monitor, control, and acquire data from all of the city�s water and reclaimed water systems.

Pagakis regulates all water transport, monitors an independent water treatment plant, and controls the chemical dosing of ammonia and chlorine that cleans the water. In total, these activities incorporate more than 1000 I/O points distributed across the city�s command and control center and numerous remote sites.�Currently, the SCADA system encompasses three large reservoir impounds, 14 reservoirs, and 20 pressure-reducing stations used to monitor more than 500 miles of distribution pipeline,� Pagakis said.Significantly, all of the monitoring and data acquisition functions are performed not by a single (or even multiple) central controllers, but by local I/O processors (or �brains�) distributed at pump stations and other points across the city�s infrastructure.

These brains communicate to I/O located on the same rack and perform functions normally reserved for an expensive PLC.For example, the brain takes valve readings from the analog input modules and performs scaling calculations to convert a voltage measurement into a percentage.

So, for a typical 4-20 mA analog input module, a measurement of 12 volts would result in a reading of 50%. To have this scaling and engineering unit conversion take place locally, at the I/O level, relieves the main controller from extra processing, while also providing control center personnel the convenience of being able to view and interpret easy-to-understand units of measure (i.e., percentages as opposed to voltages.)Distributing intelligence in this manner also provides a safeguard in case there�s an interruption in the operation of one of the main controllers.

The brain can be instructed to continue to record measurements and perform calculations, and operators can continue to vieBecause water supply and sewerage facilities are important for safe and comfortable lives, they must be properly managed and operated.Supervisory Control and Data Acquisition (SCADA) is a technique for quickly and accurately identifying the operational status of water supply and sewerage facilities. Automatic control enables smooth and smart operation of the facilities, making it easy to achieve the target water quality and conserve energy.In addition, SCADA allows a management center to keep track of facilities such as purification and sewage treatment plants dispersed across a wide area via external communication lines.

Therefore, SCADA can be adapted to various applications in a flexible manner such as wide-area management of plants and unattended operations. OverviewToshiba offers easy-to-use operation systems for operators by leveraging its expertise and decades of experience in the monitoring and control of water supply and sewerage plants.

These operation systems allow quick and accurate monitoring of the real-time operating states of power receiving and transforming equipment, components, devices and instruments in water supply and sewerage facilities.

This implies a continuous supervision of the water supply process in order to allow any problem that could appear to be solved, and in the same time, to maintain normal functioning parameters. Proper solutions imply automation and monitoring architectures which contain: a supervision and control system for the real time installation, programmable logic controllers with basic functions (communication, adjusting, measuring, etc.) libraries, communication systems, standard interfaces or dedicated ones with sensors, electrical drive elements, measuring devices, etc.

The informatics systems present the possibility of preventing some phenomenon, by analyzing and processing the data, leading to an optimum functioning and to important financial economies. In this way, the paper presents a SCADA system for the monitoring and control of the technological parameters in the water distribution stations, which will allow the optimum functioning of the pumping system, safety and endurance growth in the equipments and installations exploring, and so obtaining efficient energy usage and optimum administration of the drinkable water. .ff0{font-family:sans-serif;visibility:hidden;}@font-face{font-family:ff1;src:url('data:application/font-woff;base64,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
