New Perspective to Water Industry
Vineet Musale, Senior Manager, Business Development,(Water & Waste Water) Siemens India Whether for the drinking water treatment, seawater desalination, sewage treatment or irrigation, Totally Integrated Automation is the answer to all demands associated with the water industry – and covers the complete hydrological cycle. Siemens offers Totally Integrated Automation platform as a unique integrated product and system basis for implementing customised automation solutions in all sectors of the water industry. Thus, Totally Integrated Automation provides the prerequisites for reliable and highly efficient water supply and treatment.

ater is the most important commodity and a resource endangered almost everywhere by excessive use and environmental pollution. Therefore there can‘t be any compromise where the sustained provision of a reliable, continuous, good quality and economical supply of drinking water and the treatment of wastewater are involved. Following are the decisive levers for success in the Water Industry.

Optimisation of Process Quality: The essential prerequisite for a successful water industry is best process quality. The perfect conditions for this are provided by Totally Integrated Automation using SIMATIC PCS 7/SIMATIC PLC and SIMATIC WINCC process controlsystem. This innovative process control system controls all processes throughout the plant and provides the basis for effective and safe process management. Widely distributed or remote plants such as pumping stations can be controlled and monitored extremely efficiently using Telecontrol eg SINAUT, thus being completely integrated into the plantwide, uniform optimisation of operations management.

Reduction of Life Cycle Costs: Totally integrated automation provides numerous advantages during the initial planning phase and engineering. The unique integration of all the devices and the common hardware/ software platform, which are based on proven international standards, reduces interfacing requirements to a minimum. In addition, solutions can be perfectly scaled and tailored to the actual requirements and demands. Over dimensioning or under dimensioning is thus eliminated. Since the hardware and software components used are subject to different innovation cycles, we provide partial and total migration solutions, which safeguard the investments already made.

Ensuring Sustainability: In the context of totally integrated automation, Siemens offers a complete range of products and systems thus making an active contribution to protecting the environment in the manner that the emission of CO2 is significantly reduced by their use. Whether plant owner, system integrator, planning engineer or machine constructor; with its unique integration, it offers a wide range of advantages throughout the complete life cycle of a plant.

Design and Engineering: Intelligent tools provide support in selecting appropriate components and the optimum plant design, thus ensuring maximum planning reliability. System-oriented and integrated engineering minimises the overhead for configuration and commissioning. Automation solution scan then be implemented significantly faster, safer and more economically.

Installation and Commissioning: The consistent use of established standards such as Profibus and Profinet for plant-wide communication reduces interfacing requirements to a minimum and simplifies installation and commissioning. Even extremely complex plants can be implemented with significantly less effort.

Operation: Integrated communication provides maximum transparency throughout the plant. This means that plant owners can react much faster and more flexibly to changes in requirements and implement extremely effective diagnostics concepts. This is an extremely efficient lever toward minimising unplanned downtimes. Integration on the basis of totally integrated automation also means uniform operation for all stations, irrespective of whether they are local or remote.

Maintenance: Intelligent maintenance strategies allowfaster detection, analysis and elimination of potential sources of error, even usingremote maintenance. If modules have to be replaced, this can be carried out during theon-going operation with many of our systems. Service engineers benefit from the uniform look and feel of our components.

• Modernisation and Expansions: Existing plants can be adapted to changing requirements without problem, often with out interrupting operation. The continuity in the further development of our products and systems always ensures a high level of investment security through the avoidance of unnecessary changes in the system.

Drinking Water Treatment Plant As far as the drinking water supply of metro cities, towns or a rural area is concerned: the water is brought from dams or rivers. It is treated in the treatment plant and then transported into supply network. The transportation requires the long piping lines, pumping stations and reservoirs. All these various sections are generally far apart from one another and may be unmanned/ unattended. It is therefore important that the components used for this purpose must be with maximum ruggedness and reliability and also interact perfectly with regards to the process control technology, the drive and automation engineering, the process instrumentation, the power supply, and the complete networking.

In order to always be up to date on the component status, it is essential to have an overview of all relevant information e.g. pump performance, current flow rate, quality data, etc continuously. And this depends on efficient operator control and monitoring of the plant processes. Siemens provides end to end solution for the same. For Water treatment plant, automation is done using Simatic PLCs and Simatic WinCC Scada. While Pumping station automation is done via Simatic Micro Controllers, Simatic HMI & SINAUT Telecontrol. Successful automation operations of any water treatment plant depend on how reliable and accurately you measure the process parameters in the field.

To ensure the same Siemens also provides the ever reliable Field Instrumentation, VFD, Motors and low voltage switchgear products and panels, which are communication capable either on Profibus or Profinet, thus allowing to have a seamless integration of all the products used in the entire water network from water intake to water supply. As these products are based on totally integrated automation concept, the plant control and monitoring is easily possible either locally or remotely.

Wastewater Treatment Plant The numerous purification steps in a sewage treatment plant from the screen house up to the clarifier must match perfectly. Only then is it possible to guarantee a high purification performance with optimum use of the equipment. In this context, the highly precise units from our comprehensive range of process instruments play an important role. They constitute the eyes and ears of the process.

The information acquired by them is continuously collected by the SIMATIC PCS 7 system. Our process control system additionally makes this information available for process control and optimisation also with regard to optimised maintenance and repair. Motors are connected via SIMOCODE pro, our multifunctional motor management system. This transparency can also be achieved if individual plant components such as pumping stations are located far away from one another. In such cases, our SINAUT telecontrol system provides reliable data transmission.

Totally Integrated Automation
With totally integrated automation, Siemens is the only supplier of a comprehensive and integrated range of automation products and systems for plants of any size across all the sectors. Whether for the process or production industry, totally integrated automation is the unique basis for implementing automation solutions perfectly matched to the specific requirements, whatever the sector. The experiences gained from the cross-industry applications of our tried and tested products flow directly into our development work, which in turn benefits the water industryacross the entire process chain.

A complete plant can be automated uniformly and extremely efficiently on the basis of totally integrated automation. In the case of sewage treatment plants: from the lifting station via the activation tanks all the way up to the effluent station for the complete plant life cycle.

Totally integrated automation provides advantages during the complete life cycle of a machine or plant from the initial planning steps, through installation and commissioning, operation and maintenance, up to expansions and modernisation.
