Xylem Inc. is a large American water technology provider, in public utility, industrial, commercial, agricultural and residential settings.

Launched in 2011 as the spinoff of the water-related businesses of ITT Corporation, Xylem is headquartered in Washington, DC, with 2024 revenues of $8.6 billion and 23,000 employees worldwide.

[10][11] Loranger was chairman, president and CEO of ITT Corporation when it spun its water businesses off as Xylem in October 2011.

[14] In May 2024, Xylem, in partnership with the German city of Weissenburg and the Technical University of Munich, launched a revolutionary water-related initiative, Reuse Brew.

This process, utilizing technology developed by Xylem, involves ozone injection, ultraviolet radiation, hydrogen peroxide pellets, and filtration through carbon and nano filters.

Through a newspaper advertisement the two companies are brought into contact with one another in 1929, and led to the Stenberg brothers beginning to produce Flygt pumps in Emmaboda.

These three units are interconnected, anticipating and reflecting evolving needs and sharing their applications expertise to cover every stage of the water cycle.

HYPACK, a leading producer of hydrographic data acquisition and processing software, was acquired by Xylem in November, 2015.

[22] YSI, a Xylem brand, is a developer and manufacturer of sensors, instruments, software, and data collection platforms for environmental water quality monitoring and testing.

[23] The company reaches back to 1948 when a three-man partnership was forged at Antioch College in Yellow Springs, Ohio, US.

This village, between Dayton and Columbus, still serves as the headquarters for what started as the Yellow Springs Instrument Company, and later became YSI Inc.[24] In 1985, Malte von Matthiessen succeeded Hardy Trolander as president.

In 2011 Ron Geis was appointed new general manager of YSI; former CEO Rick Omlor continued as executive advisor.

In 2009, Design Analysis Associates in Logan, Utah, a manufacturer of data loggers and radar level sensors was acquired.

In other analytical instruments, they produced the first practical dissolved oxygen meter for field and laboratory use in 1965, which the same magazine recognized as yet another of the most significant technological products of the year.

[28] Their oxygen meter had used the technique of polarography, and they developed further products on the same principle, including the first immobilized-enzyme-activated polarographic sensor in 1972.

They also continued developing thermal technology, with the first commercial gallium melting-point temperature standard (29.7715 °C) in 1977 and the first robotic-manufactured glass-encapsulated precision thermistors in 1996.
