Advanced technologies for water reuse Utilities and businesses around the world have reused 18.1-billion cubic meters of water since 2019, enabled by solutions from global water technology leader Xylem, the Company revealed in its most recent Sustainability Report. That volume is enough to meet the annual water needs of more than 350-million people, based on global use estimates.

R euse is just one part of a broader effort to increase global water secu rity, alongside the implementation of advanced treatment and digital technologies. Water managers are using the innovations to protect water sources, remove contaminants, reduce emissions and make water infrastructure more resilient. South Africa is a major consumer of water, despite below-average global rainfall that is dis tributed unequally across its geography. South Africans use an average of 235 litres per capita each day, a third higher than the global average of 173 litres. Water reuse and conservation practices, including rainwater capture and drip irrigation, are spreading among local commu nities, spearheaded by organisations such as Xylem Watermark and its partners. “Our customers are tackling the world’s toughest water challenges,” said Matthew Pine, Xylem President and Chief Executive Officer. “Their results show the impact of scal ing proven technology solutions to strengthen water systems. The work they do empowers businesses and communities to become more water-secure.” In 2019, Xylem launched its 2025 Sustainability Goals, including several target ing the positive impact its technology enables for its customers. Since then, Xylem solutions have enabled customers to: • Reuse 18.1 billion cubic meters of water, extending the lifecycle and value of fresh water. In the US, a global spirits manufac turer identified opportunities to reuse more than 3 785 m 3 of water annually. • Reduce non-revenue water in distribu tion networks by 3.7-billion m 3 . In Spain, a provincial water utility avoided two major

pipeline failures and prevented leaks, saving 25 000 m3 of water each year with predictive monitoring and analytics. • Prevent 10.7 m3 of polluted water from entering waterways. In the U.S., an ad vanced treatment service is enabling industrial manufacturers to remove heavy metals from wastewater, reduce hazard ous waste and minimise discharge to local waterways. • Reduce water-related CO 2 e emissions by more than 6.4 million metric tonnes. In Eastern Europe, a food processor cut energy use by 33% with an upgrade to smart aeration technology. Xylem achieved all four of its 2025 Customer Sustainability Goals ahead of schedule. Building on that momentum, the company has set a bold new target: enabling customers to reduce annual water demand by 2 billion m3 by 2030. “We partner with our customers to advance their sustainability ambitions, creating positive impact in the communities we all serve,” said Claudia Toussaint, Chief Sustainability Officer at Xylem. “This report shows how our com mitment to sustainability leadership enhances

Xylem’s competitiveness in the marketplace. By embedding sustainability in every aspect of our business and culture, we are empowering our customers and communities to achieve the water security essential to health and economic growth." Xylem’s impact also extends across its value chain. In 2024, 43% of Xylem’s supplier spending supported partners aligned with WASH4Work, a global initiative focused on expanding access to clean water, sanitation, and hygiene. “Every drop we can reuse is a win for our communities,” says Chetan Mistry, Strategy and Marketing Manager at Xylem Africa. “We see success when we work closely with community members. We provide the materials and equip ment, and experts who share their knowledge, but it's the community that makes a difference. There are also gains for water recycling among local mining, agriculture, and the public utility sector." The country could face a 17% water deficit by 2030, according to the Development Bank of South Africa. Yet, it can make up that shortfall through active water recycling and reuse. With Xylem's help, South Africa is making water more sustainable.

Water reuse and conservation practices, including rainwater capture and drip irrigation, are spreading among local communities, spearheaded by organisations such as Xylem Watermark and its partners.

“By embedding sustainability in every aspect of our business and culture, we are empowering our customers and communities to achieve the water security essential to health and economic growth," says Xylem Africa’s Chetan Mistry.
