Mapping the Intelligent Water Network—
Embarking on a New Journey for Sustainable Development
As sustainable development becomes a global consensus, the convergence of the global water crisis, intensifying climate change impacts, and the digital technology revolution
places the water industry—which is vital for people's well-being and green development—at the forefront of unprecedented missions of our time. United Water has consistently
integrated sustainable development into all facets of its operations and development, creating value for the economy, the environment, and society, while leveraging the Company's
expertise to protect aquatic ecosystems and empower water-related livelihoods.
Faced with the profound challenges posed by climate change, we firmly believe that scientific and technological innovation holds the key to breakthrough solutions. We actively
embrace the latest trend of technological revolution led by artificial intelligence, positioning the cultivation of "new productive forces" as the core engine of our green transformation.
To this end, we are accelerating the development of smart water systems and deeply integrating technological and ecological elements. We are not only exploring low-carbon,
high-efficiency models in our daily operations—contributing scientific and technological power to water resource protection, water environment improvement, and water ecological
restoration—but also investing in emerging sectors such as carbon-negative materials with a forward-looking vision, introducing cutting-edge environmental protection technologies
into the industry and fully activating our momentum for green development.
Water sustains communities and water supply serves the people. While pursuing green growth, we consistently adhere to our mission of "ensure the provision of high-quality water
to consumers and eco-friendly water treatment services that contribute to environmental protection," placing "the creation of social value" at the Company's core. Domestically, we
coordinate urban and rural water development, bringing clean, flowing water to thousands of households. Internationally, we actively expand new horizons for cooperation, advancing
global water governance through our professional capabilities. Beyond water services, we are deeply committed to rural revitalization and public welfare, delivering warmth and
care through practical actions. We are dedicated to a people-oriented principle, safeguarding employee rights, and building a platform for every employee to realize their self-value,
fostering mutual growth between individuals and the organization.
Currently, ESG has become an imperative for businesses. With strategic foresight, United Water has internalized ESG principles as an impetus for its development. Through robust
operational performance and transparent governance practices, we are creating long-term value for all shareholders. The Company's solid ESG management practices have earned its
recognition in 2025, including being selected as the "2025 Outstanding Sustainable Development Practice Cases of Listed Companies" by the China Association for Public Companies
(CAPCO), the "19th Listed Companies Value Selection·China Listed Companies ESG TOP 100" by Securities Times, and the "2025 Wind China Listed Companies ESG Best Practice TOP

the degraded conditions of the pond slopes—this project plans to utilize two patented technologies: "A Modular Constructed
Wetland Water Quality Purification System" and "A Non-Point Source Pollution Control System for Riverbank Slopes",
establishing a tiered purification system comprising an "ecological filter bed + ecological pond." In this system, the ecological
filter bed provides enhanced purification of tailwater from the rural domestic wastewater treatment station, resolving issues
of random discharge and subsequent water quality deterioration upon entering the pond. In terms of the ecological pond, it
performs advanced purification of the filter bed effluent, and combines with slope management projects (employing vegetation
belts, ecological interception ditches, etc.) to intercept pollutants from surrounding surface runoff. By constructing a baseline
ecosystem, the system enhances the water self-purification capacity, addressing algal blooms and eutrophication caused by the
long-term accumulation of existing pollutants in the pond. The integrated system effectively overcomes the challenges of low
purification efficiency during winter in northern regions. It not only achieves full-process tailwater treatment and water resource
recycling, but also improves the slope landscape, providing significant practical support for the construction of the Yuncheng

A New Chapter in Overseas Water Utilities
United Water actively practices the principles of extensive consultation, joint contribution, and shared benefits under the Belt and Road Initiative, using water as a bond to closely connect Chinese standards and
technologies with overseas livelihood needs. As Bangladesh's first water PPP project, the Purbachal New Town Water Supply Project in Dhaka, signed in 2019, represents not only a milestone in the Company's overseas
expansion but also a model livelihood project under China-Bangladesh Belt and Road cooperation. With a designed capacity of 340,000 cubic meters per day and a high-standard water quality testing center, the project
will provide high-quality water services to approximately 2 million residents. Following the operation of Phase I in early 2023, Phase II of the project is expected to be completed by the end of June 2026 and to deliver
water to customers later in 2026. The Company has extended its mature service system to international markets, comprehensively building a sustainable local water supply ecosystem encompassing refined water quality
management, smart pipeline network monitoring, rapid emergency response, and publicity of water usage knowledge for communities. Nowadays, safe and reliable water supply has become routine, transforming water
access difficulties in the past into tangible sense of well-being, happiness, and security for the people of Bangladesh.
In 2026, United Water successfully won the long-term operation and maintenance contract for municipal wastewater treatment (Package 10) from the National Water Company of Saudi Arabia, covering the upgrading,
renovation, and operation and maintenance of nine wastewater treatment plants across four provinces in Saudi Arabia. This successful bid represents another major achievement in the implementation of United Water's
development strategy of "rooting in the domestic market while actively exploring the international market," helping the company expand its overseas business footprint and bring clean water to more regions and residents.
