With the modular IQ Sensor Net of the brand WTW, Xylem has set standards in the field of continuous on-line measurement. Meanwhile, Xylem can look back on a 20-year success history with ten thousands of systems and sensors sold. The development of the system has progressed steadily. The list of available parameter measured and the technologies for communication continue to grow. Based on instrument and sensor technology that has been field-proven many times over, IQ Sensor Net offers an impressive level of performance and flexibility that is unique in this form. 

The system can be optimally adapted to any conceivable measurement task, even under special on-site conditions. The IQ Sensor Net communication system allows the easy integration of multiple measurement locations. This results in a significant reduction in costs while maintaining full functionality.

Xylem author teaches children about the wonderful world of water

Different versions of the book The Great Book of Water present local water issues in Latin America, Europe, India and Oceania: 

The Great Book of Water

The Great Book of Water helps children and curious adults around the world learn about water and how it touches every part of our lives. The book was originally written in Spanish for and about Latin America by Xylem’s Denise Pouleurs to fill what she saw as a gap in the market.
Here's her story (click)
Today, it is available in multiple languages. Several authors and translators have worked on adapting the book for other regions. The Great Book of Water can be used in Latin America, Europe, India, Australia and New Zealand to educate children aged 10 and older about water.
It contains interesting facts about water – from the water cycle to agriculture and human history. Detailed illustrations show the structure of sewers, wastewater treatment plants and groundwater and convey a careful attitude towards water resources and nature.
