The Administrative Measures for Reclaimed Water Utilization of Wuhan Municipality (Wu Huan [2026] No. 73), jointly issued by the Wuhan Municipal Bureau of Ecology and Environment and the Municipal Water Affairs Bureau, will officially take effect on August 15, 2026, with a validity period of five years. This is a local document that systematically regulates the planning, construction, operation and supervision of reclaimed water in Wuhan, marking the entry of the "second water source" strategy of this core city in the Yangtze River Economic Belt into a new stage of institutionalized, market-based operation, and opening clear institutional space for environmental enterprises to participate in reclaimed water operation.

1. Key Signals Released by the Measures

The measures provide institutional safeguards for reclaimed water utilization across multiple dimensions. In terms of the operating model, it encourages mechanisms such as concession operation and entrusted operation, improves the integration of investment, construction and operation of reclaimed water utilization facilities, and guides social capital to participate in facility investment, construction and operation; in terms of coordination and alignment, it requires reclaimed water utilization to connect with urban renewal, the green transformation of industrial parks, and ecological environment treatment projects, expanding effective investment and the policy dividends related to expanding domestic demand; in terms of investment and financing, it guides financial institutions to provide diversified financing support such as green credit, green bonds and special bonds for reclaimed water utilization projects, broadening project funding channels; in terms of technical application, it encourages "multiple uses for one water and recycling", promotes the clean-energy technology of reclaimed-water-source heat pumps, and prioritizes the use of reclaimed water for industrial production, municipal miscellaneous uses and ecological water replenishment.

2. From "Project Mindset" to "Systematic Operation"

For a long period in the past, reclaimed water projects mostly remained at the level of engineering construction, emphasizing construction over operation, which led some facilities to be "built but unused, or used below capacity". The Wuhan measures emphasize "integration of plants and networks", encouraging reclaimed water operators to participate in the operation and management of urban domestic wastewater collection and treatment facilities and municipal drainage facilities — precisely to genuinely bring reclaimed water into the city's unified allocation of water resources and its routine operation system. This approach is highly aligned with the Implementation Plan for the Three-Year Action on Advancing Reclaimed Water Utilization in Key Cities, which calls for "positive results in expanding reclaimed water utilization scenarios in key cities by 2026", and echoes the mature experience already explored by cities such as Shenzhen and Shijiazhuang.

3. The Reference Value of Cross-Regional Demonstration

Nationwide, reclaimed water utilization is moving from "pilot exploration" toward "scale promotion". Shenzhen has promoted large-scale, high-efficiency utilization through a transmission and distribution pattern of "network extension and point layout" driven by both government and market; Shijiazhuang has fully incorporated reclaimed water into its water resources allocation system, with a utilization rate exceeding 60% in 2025; and Hangzhou, Guangzhou and other cities continue to expand into scenarios such as elevated irrigation and industrial cooling. The introduction of the Wuhan measures means that this hub city in the middle reaches of the Yangtze River has officially brought reclaimed water operation onto the track of the rule of law, and is expected to form a replicable "central-region model" in the future.

4. TIANYI TECH's Point of Entry

For TIANYI TECH, the Wuhan measures send a clear regional market signal: reclaimed water is not only a "technical task" but also an "operating business". The company can build on its technical accumulation in industrial wastewater treatment and water reuse to explore an "investment-construction-operation integration" service model — from reclaimed water treatment process packages, intelligent chemical dosing and online monitoring, to regional reclaimed water operation and custody — helping Wuhan and cities in the Yangtze River Economic Belt turn policy dividends into implementable projects. In particular, in green transformation scenarios for industrial parks, TIANYI TECH's segregated treatment and water reuse solutions can connect directly with the concession operation and plant-network integration directions advocated by the measures.

Conclusion

With the measures about to take effect, whoever combines technical capability with service models more tightly will go further in this wave of marketization. For TIANYI TECH, the Wuhan case is not only a regional opportunity, but a touchstone for testing the "technology + operation" dual-wheel-drive strategy. We look forward to working with city operators and park enterprises to make reclaimed water a truly reliable "second water source" for the city's high-quality development.
