In celebration of World Water Day on March 22 and Earth Day on April 22, Xylem hosted the second annual Make Your Mark 30 Day Challenge, a month-long event that encourages employees to engage in efforts to solve global and local water and environmental issues. The 30 Day Challenge is a signature event of Xylem Watermark, the company’s corporate citizenship platform aimed at providing and protecting safe water resources in communities in need and educating people about water issues. This year, 1700 employees volunteered in more than 190 water-related activities across 93 Xylem sites, including leading students through water presentations and water monitoring, and building water towers in communities that lack access to clean drinking water.
