According to Market Research Future, the china water wastewater treatment equipment market is experiencing significant growth, driven by increasing urbanization, stringent environmental regulations, and a growing emphasis on sustainable practices. The China water and wastewater treatment technology market was valued at USD 16.07 billion in 2025 and estimated to grow from USD 17.39 billion in 2026 to reach USD 25.78 billion by 2031, at a CAGR of 8.20% during the forecast period (2026-2031). The market is a critical segment within the global water treatment industry, addressing the country’s pressing water scarcity and pollution challenges.
Understanding the China Water Wastewater Treatment Equipment Market
The market is segmented by equipment type into treatment equipment, process control equipment, and pumps. Treatment equipment accounted for 90.02% of the China water and wastewater treatment technology market share in 2025 and is projected to expand at an 8.39% CAGR through 2031. Membrane bioreactors, advanced oxidation units, and multi-stage filtration lines form the backbone of Zero-Liquid-Discharge (ZLD) compliance as well as ultrapure-water fabrication demands. The market serves municipal water and wastewater treatment, food and beverage, pulp and paper, oil and gas, healthcare, poultry and aquaculture, and chemical industries.
The market is characterized by a dynamic competitive landscape, with major players such as Veolia (FR), SUEZ (FR), and Xylem (US) strategically positioned to leverage these trends. Veolia focuses on innovation and digital transformation, while SUEZ emphasizes partnerships and regional expansion. Xylem is committed to sustainability, integrating eco-friendly solutions into its product offerings. Local firms are also closing the technology gap by licensing thin-film composite chemistries.
Key Market Drivers and Regulatory Framework
The adoption of national discharge standards is a primary driver, with China having strict discharge requirements using such standards as GB 8978 and Class A and B local regulations. Existing systems must be upgraded with tertiary processes to qualify for pollutant levels of nitrogen, phosphorus, and chemical oxygen demand. Industrial Zero-Liquid-Discharge mandates compel more than 15,000 chemical, pharmaceutical, and textile sites to recover 95% of process water or face penalties up to USD 1.5 million.
The increasing demand for water reuse facilities is another significant driver. To mitigate freshwater shortage, China has rolled out policies encouraging wastewater reuse in agriculture, industry, and urban services. The targets of government in water recycling are integrated into Five-Year Plans in order to secure long-term investment. The 14th Five-Year Plan allocates USD 75 billion specifically to water infrastructure, with 60% slated for Public-Private Partnerships (PPPs) that guarantee 20-30-year service payments.
Industrial modernization programs like Made in China 2025 focus on clean production and environmental compliance. Climate change and water resilience strategies are also necessitating the integration of water resilience into planning processes, with decentralized and mobile facilities being preferred as tools for emergency deployment.
Challenges and Opportunities
High operating costs for sophisticated systems present a challenge, as advanced tertiary technologies tend to have high chemical, energy, and maintenance costs. Inequitable policy implementation across regions and infrastructure constraints in rural areas are also key challenges. However, government support and eco-city master plans finance the installation of high-end water treatment solutions within new green industrial parks and eco-cities. New opportunities lie in the integration of IoT technologies for smart water management solutions, as seen in Veolia’s strategic partnership with a leading Chinese technology firm.
Future Outlook
The China water wastewater treatment equipment market is projected to grow at a 5.62% CAGR from 2025 to 2035, driven by urbanization, regulatory pressures, and technological advancements. New opportunities lie in digitalization, sustainability, and the integration of AI technologies. As China continues to prioritize environmental sustainability and water resource management, the market is expected to achieve substantial growth by 2035.
