2 supplied by Siemens allow users to standardize the project engineering of new water treatment facilities. This cuts down the time required for planning new plants with a similar requirement profile and also improves planning safety. The Water management System SIWA is designed to help water and wastewater network operators to optimize their operations with a range of evident benefits: Alongside improved supply reliability, plant operators can reduce their energy consumption and consequently also their costs. By providing its customers with a closely meshed global sales and servicing network, Siemens is able to provide across-the-board support to a water industry that is becoming increasingly globalized, in which water treatment facilities are frequently planned in one country and constructed in another. Dynamic market environment Corporations operating plants and providing infrastructure for the supply of drinking water and the purification of wastewater are faced today by a number of key challenges. Guaranteeing supply reliability and product quality, reducing plant life cycle costs, complying with statutory requirements and ensuring economic sustainability are all issues confronting the water industry on a global basis. At the same time, the market environment for plant constructors and operators is both dynamic and characterized by marked regional differences. Activity in the European market is currently dominated by the modernization of existing drinking water treatment and wastewater purification facilities. Central national markets here include for instance Germany, Spain, France and the UK. Here, plant operators and water utility companies find themselves faced with rapidly changing market conditions. The increasing privatization of water treatment facilities means that in some cases state subsidies can no longer be relied upon. More than ever before, plant operators have no choice but to drive down costs and economize through the careful, efficient use of resources. In the emerging markets, different conditions prevail. Here, the overwhelming objective is to first and foremost provide the population with high-quality drinking water. As investment here is concentrated on the development of a functional infrastructure, with new and in some cases extremely large facilities being constructed, high growth rates prevail in these markets, which include predominantly the BRIC states as well as Mexico, the Middle East and the ASEAN (Southeast Asian) region. Development in these markets is highly dynamic. India is a Page 2/7

3 particularly interesting region with a large number of water transport and wastewater treatment projects currently in progress. Other emerging economies such as China are also investing heavily in their water infrastructure, says Ronald Vrancken, Head of Vertical Water & Wastewater at Siemens Industry. As well as pursuing its own sales activity in these countries, Siemens is primarily involved here in the form of partnership projects with system integrators, planners and water specific machine builders which are aimed at leveraging the potential offered by these dynamic markets. Countries and regions poor in water resources, for instance in the Middle East, North Africa or Spain, are primarily in need of seawater desalination plants, a field in which Siemens is in demand not only as a supplier of smart control technology and energy-efficient solutions but also as a globally active partner to facility planners, constructors and operators. The company provides support right across the entire plant life cycle from the design stage through planning, engineering and operation to maintenance and modernization. We aim to drive forward processes for drinking water treatment and water desalination to a higher level using both smart solutions and classical drive and automation technology, explains Ronald Vrancken. Saving time spent on planning and engineering Time is money. Nowhere else does this adage apply so aptly as to the costly and time-consuming planning phase. With its high-performance software tools and systems, Siemens offers a way of making drastic time savings at this crucial stage. The Plant Engineering Software Comos, for instance, saves time by allowing water treatment, sewage or desalination system planning at the computer, from the process engineering stage through to automation. By using a single data platform, the system allows different trades to be planned on a parallel basis, saving up to 20 percent of the time normally spent on engineering. Modular libraries such as the Industry Library and Water Templates additionally support automation engineering and allow project lead times to be cut by another 15 percent. A consultant DVD containing a wide range of prepared specification text modules, manuals, product information and quick links provides a valuable tool for engineering consultancy firms and planners. Alongside CAE-aided design, virtual tests and simulations also help enhance productivity. The computer-aided simulation system SIWA Concept, for instance, allows pipeline networks to be tested prior to commissioning, so preventing pipe factures and other potential damage. The system calculates the Page 3/7

4 hydraulic behavior of water supply systems, taking into account dynamic information from all measurement points for optimum transparency of complex correlations and work flows. These systems are also used offline for training new operator teams, to prepare personnel for coping with different operating situations in practice. Technology portfolio for profitable solutions in the water industry More than any other industry supplier, the name Siemens is synonymous with a comprehensive, integrated drive and automation technology portfolio. This applies equally in the water and wastewater treatment industry. Alongside the control technology of the Simatic family and the SIMATIC PCS 7 process control system, the Siemens industry-specific portfolio also encompasses process instrumentation for level, flow, pressure and temperature measurement. The Simatic PDM (Process Device Manager) integrated in the Simatic PCS 7 allows the simple operation, parameterization and maintenance of field devices. Another central element are network management solutions. Many water supply systems are decentralized in structure. In some regions, a city s central water treatment facility can be supplied by 20 or more water sources located within a radius of 50 km. To ensure the reliable monitoring and control of field stations such as water towers, pumping stations and stormwater overflow tanks, the integration of all system components under a central control system such as Simatic PCS 7, and the use of telecontrol technology and remote communication services are vital. In this field, Siemens offers a broad-based technical portfolio to ensure cohesive and reliable communication from the control centre to remote field stations. Data transmission solutions range from local networks over Profinet, Profisafe, AS-Interface or HART through Internet-based solutions using for instance Scalance switches, to systems with mobile radio communication. Components designed to cope with tough, demanding ambient conditions such as Ruggedcom Switches are just as much part of the mix as special solutions for redundant telecontrol networks such as the Remote Interface Control system Siplus RIC. The field of industrial controls is covered by contactors, relays and modules from the Sirius series or the multifunctional motor management system Simocode pro for lowvoltage constant-speeddrives. The system combines all the necessary protection, monitoring and control functions in a single unit, and is ideally suited for drives used for pumps as well as bars and valves. With its Sinamics, Micromaster and Robicon product families, Siemens offers a practically seamless range of durable, reliable Page 4/7

5 drive systems covering an output spectrum from just a few kilowatts to the doubledigit megawatt range. This wide selection allows suitable solutions to be found for optimized process quality and low operating costs, no matter what the process, by using an economical plant operation mode. Reliable power supply using Sivacon rounds off the offered range. Modular Sivacon systems with communication capability make available measured values and switching statuses to higher-level energy management applications. With the management system B.data, users can analyze their energy consumption and use the results to selectively drive down their usage. Wide-ranging approaches to achieve energy efficiency Energy consumption is an important lever which can be used to enhance the economy of water supply and sewage facilities. On average, energy accounts for 30 percent of the costs involved in plant operation. Siemens adopts three main approaches to uncover and eliminate energy guzzlers, or to optimize their consumption. Firstly, a key role is played by smart water solutions intelligent, software based tools. SIWA Optim, a module of the water management system SIWA, is one of them. This software application ensures the economical use and supply reliability of pumps. Using mathematical optimization methods and energy provider rate structures, the system calculates the most economical pump, well and water tank schedules. Other scenarios can also be determined such as the optimum timing of maintenance interruptions, suitable pump sets can be selected or optimum efficiency ensured for pumps with fixed and variable speeds. Experience has shown that using SIWA Optimum can cut electricity costs by up to 15 percent. The power consumption of pumps, fans and compressors can also be reduced by up to 70 per cent by replacing ageing drives with the latest generation of energyefficient drive systems from Siemens. Speed-controlled motors with frequency inverters help to save energy, as they only consume the amount of power thatis actually required. They also eliminate start-up current peaks and ensure controlled shutdown of the system. This increases the service life of the components used, and also allowing them to respond more quickly to requirement fluctuations than mechanical control elements. The third approach taken by Siemens to energy saving is the energy audit. In the foreground here is ensuring transparency in terms of actual energy consumption. Page 5/7

6 This can be achieved using for instance the multifunctional power meter Sentron PAC Once the values are known, the savings potential can be analyzed. Working together with the customer, the necessary measures can then be determined and implemented. This allows, for instance, pumps with worn wheels or increased cracks to be discovered at an early juncture due to their specific power consumption and flow rate. This early diagnosis helps to reduce energy consumption and also to increase plant availability and supply reliability. The energy audit is a customized energy supply concept including calculation of all the various technically and economically feasible options. Enhancing supply reliability with smart water solutions There are enormous pricing pressures currently acting on the water and wastewater plant market. Our customers in this market are searching for powerful partners capable of understanding the problems they face and coming up with solutions quickly, says Ronald Vrancken. Using smart water solutions like the water management system SIWA from Siemens, water supply network operators can be sure of control and monitoring solutions which are both smart and energy efficient. Leakages which cause loss of water en route to consumers represent a huge problem in many cities around the world. These not only entail the loss of immense volumes of treated drinking water, they also threaten to cause enormous damage to roads and buildings due to washout and corrosion. One analysis performed in London highlighted an average water loss of 30 percent as a result of leaks. In new or well maintained supply plants, this loss can be reduced to below three percent. Using a specially developed leak detection concept, Siemens allows losses to be detected and localized. This involves analysis of the pipe network and the systematic localization of water losses, using a solution comprising measuring devices and smart software IT modules which can quickly pinpoint even small leaks to within a range of just one meter. This allows selective repairs to be carried out and ensures that precious treated water reaches the consumer instead of leaking out into the soil. In this way, we support plant operators in their bid to reduce the proportion of non-revenue water and consequently lost earnings, explains Ronald Vrancken. This helps increase the profitability of plant operators and at the same time increases supply reliability. Page 6/7

7 The future s smart Looking to the future, Siemens engineers continue to work on the development of smart systems which will contribute towards even more effective control of water supplies and ensure optimum preparation for peak loads, with a view to further enhancing profitability for plant operators. This type of system could ensure the smart rerouting of wastewater flows in case of heavy rainfall, for instance, to prevent damage or contamination due to sewage system overflow. In the future, success for plant operators and municipalities will depend more and more on smart water solutions for the intelligent, resource-saving management of infrastructure and water treatment facilities. Vrancken: By further developing our integrated solutions comprising automation and drive technology, and also our industrial software, Siemens will be making a vital contribution to increased efficiency in the water and wastewater industry. Our aim is to provide our customers with the powerful smart water solutions of the future.
