Market Insights & Analysis: China Water and Wastewater Treatment Technology Market (2026- 2032):

The China Water and Wastewater Treatment Technology Market size was valued at around USD 18.91 billion in 2025 and is projected to reach USD 27.38 billion by 2032. Along with this, the market is estimated to grow at a CAGR of around 5.43% during the forecast period, i.e., 2026-32. The China Water and Wastewater Treatment Technology Market is positioned for sustained expansion supported by regulatory enforcement, infrastructure modernization, and accelerating digital transformation. National policy focus has shifted from capacity creation alone toward quality-driven, technology-enabled water governance, increasing long-term demand for advanced treatment systems, smart monitoring platforms, and low-carbon solutions.

Government-led river and lake restoration programs covering more than 2,500 major water bodies are intensifying requirements for wastewater collection, industrial park treatment upgrades, and nutrient load reduction. These initiatives extend beyond municipal boundaries, drawing industrial and agricultural wastewater streams into formal treatment networks and raising adoption of advanced biological, membrane-based, and digital control technologies. At the same time, China’s objective to achieve at least 95 % sewage treatment coverage in county-level cities and expand reclaimed-water use in water-stressed regions continues to unlock multi-year investments in pipelines, treatment plants, and reuse infrastructure.

Technology adoption is becoming a defining feature of the market. Smart water platforms integrating AI-based analytics, real-time sensors, and automated dispatch systems are increasingly deployed at the city level, as exemplified by Fuzhou City’s platform connecting 3,000+ monitoring points, enabling AI-driven wastewater management and early-warning control. Industry exhibitions held in China during 2025, such as the WATERTECH CHINA 2025 expo in Shanghai, also demonstrate strong engagement with emerging technologies and innovation in wastewater treatment.

In addition, continued policy backing, digital water governance, and low-carbon treatment mandates are expected to shift demand toward intelligent, resilient, and resource-efficient wastewater technologies, supporting steady market growth and deeper technology penetration across urban and industrial systems.

China Water and Wastewater Treatment Technology Market Recent Developments:

December 2025: The Asian Development Bank (ADB) and China Water Affairs Group (CWA) signed a USD 150 million financing package to modernize wastewater infrastructure in Ningxiang City, including a new 100,000 m³/day smart wastewater plant and updates to existing facilities, boosting treatment capacity and asset resilience.
May 2025: Veolia finalized a USD 1.75 billion acquisition of the remaining 30 % stake in Water Technologies & Solutions (WTS) from CDPQ, gaining full ownership. This strategic move strengthens its global water treatment tech business, supporting advanced solutions applicable in China’s industrial and municipal wastewater sector.

China Water and Wastewater Treatment Technology Market Drivers:

Stringent Government Regulations

China’s regulatory framework for water pollution prevention has become a foundational driver of wastewater treatment market growth. At the heart of this effort is the Water Pollution Prevention and Control Law, which mandates strict controls on pollutant discharge and strengthens enforcement mechanisms. Under this law, all entities discharging wastewater must obtain a pollutant discharge license and ensure effluent quality meets national or local discharge standards before release; violations can lead to fines, production suspension, or closure.

The State Council’s environmental targets emphasize expanding sewage infrastructure. For example, in 2025, China aims to increase daily sewage treatment capacity by 12 million m³ and expand sewage networks by 45,000 km, reflecting aggressive regulatory and infrastructure enforcement. According to the State Council’s guidelines, achieving a ≥95 % sewage treatment rate in county-level areas is a core policy target for improving compliance and environmental outcomes.

In addition, local governments can impose stricter local discharge limits than the national baseline, enabling provinces and cities to tailor regulations to water quality needs.

During the 15th Five-Year Plan (2026–2030), China is expanding its surface water monitoring network to include over 200 additional tributaries and small water bodies, enhancing compliance monitoring and creating demand for advanced treatment technologies over the long term.

Overall, these layered regulatory requirements from national discharge standards and licensing to expanded monitoring and local stricter limits compel municipal and industrial players to adopt modern wastewater treatment systems. This regulatory pressure ensures sustained demand for advanced treatment technologies, driving long-term growth in the China water and wastewater treatment technology market.
