| This year marks the 100th anniversary of one of the most significant public health advancements of the millennium: the introduction of drinking water chlorination on a large scale. In 1908, the Jersey City, New Jersey Water Works became the first U.S. water system to chlorinate on a permanent basis. The practice spread to other areas of the country, virtually eliminating waterborne diseases such as cholera, typhoid, dysentery and hepatitis A. Sodium hypochlorite (chlorine bleach) in the parts-per-million level was added to water to eliminate the micro-organisms that caused the waterborne disease outbreaks. Hypochlorite, however, was not easy to handle, and application at low feed rates was difficult and often unreliable. This problem was solved in 1913 by the Wallace & Tiernan Company with the invention of a chlorine gas feeder they aptly named the chlorinator.

| 05/05/2008 | | | The new SFC series: systematic measuring and controlling |
| The flexible SFC devices from Siemens Water Technologies constitute a new measuring and controlling series which complements the concept of the multi-functional MFC system. The SFC series is intended for single measurements of water parameters as is necessary in simple applications. One main function is controlled chemical dosing which is used when disinfectant has to be added, for example. The series of devices matches the MFC system not only in terms of design and dimensions but also in terms of the range of functions. The two types of device are based on the same software and can therefore be combined and communicate with each other via a CAN bus.

| Siemens Industrial Solutions and Services (I&S) is offering a new method of swimming pool water treatment that, unlike conventional systems, completely prevents the formation of legionellae. A combination of flocculation, ozonization, multi-layer filtration, ultraviolet irradiation and chlorination complies with the requirements of DIN 19643 for the quality of swimming pool and bath water under all the conditions tested. Dispensing with activated carbon entirely rules out any formation of legionellae. This solution from the I&S Group company Wallace & Tiernan, Günzburg, Germany, has been positively appraised by the Institut für Wasser- und Umweltanalytik GmbH (institute of water and environmental analysis), Luisenthal, Germany. The alternative method is being used in the therapy pool of the Henneberg-Kliniken in Hildburghausen, Thuringia, Germany.

| "With the new EWO Pool automation concept, Siemens is helping communities and private operators to reduce the operating costs of their swimming pools. Intelligent process technology for water and energy efficiency still have great potential for savings in respect of the water used in swimming pools", said Günter Führer, Managing Director of Wallace & Tiernan, a company of the Siemens Industrial Solutions and Services Group (I&S), during a press conference in September 28, 2006, at the Interbad trade show in Düsseldorf. EWO Pool controls central processes of swimming-pool operations and, at the same time, optimizes the consumption of water and energy. This enables annual cost savings of up to 25,000 euros. The Siemens I&S Divison Water Technologies (WT) offers a complete range of products and solutions for handling the processes involved in water processing and treatment - whether in swimming pools or in other water applications.

| 09/28/2006 | | | The CMS 3.0 visualization software from Siemens offers a higher degree of transparency in the process monitoring of water treatment plants |
| The CMS visualisation software from the Siemens Industrial Solutions and Services Group (I&S) used for the gathering, monitoring, diagnostic analysis and archiving of the process data from water treatment plants has been comprehensively enhanced. Using the new 3.0 version the visualization of process data can now take place at several PCs and up to 32 measuring and process devices can be connected depending on the configuration. As well as the German language version the software is also available in English and French which in turn makes country-specific use easier. The system from the I&S Water Technologies Division can be used for both drinking water treatment and water installations for swimming pools.
