Core Summary
Taihe Water was once a company with high expectations from the market, touted as a "star in water ecosystem technology." It went public using labels such as "algae-eating insects for restoration" and "underwater forests," but its core business was actually EPC (Engineering, Procurement, and Construction) services. The company raised funds by capitalizing on its technological reputation but operated according to the principles of an engineering firm—requiring significant upfront investments, facing slow cash flows, and dealing with complex subcontract management issues. Ultimately, it faced delisting due to consecutive losses, failing to meet revenue targets, and poor internal controls (such as inventing projects and recognizing revenues prematurely). The root cause of its failure was the mismatch between its technological claims and the risks associated with its engineering model; its capabilities did not align with the nature of its business.
Detailed Analysis
1. A Company with a Technological Facade, but an Engineering Focus
Taihe Water's technical credentials were impressive, yet it functioned more like an engineering firm:
- Business Reality: Before going public, over 95% of its revenue came from "water environment and ecosystem construction projects" using the EPC model. This meant not only designing the projects but also purchasing materials, finding subcontractors for construction, and ensuring the final water quality. The technology (e.g., algae-eating insects) was merely a core component of the project, not a standardizable product that could be sold directly for profit (like software or equipment).
- Engineering Challenges: The proportion of subcontracting costs increased significantly (58% in 2022), with tasks like dredging and installing aquatic plants being outsourced. Each new project required re-surveying, upfront funding, and waiting for the client's approval, leading to increasing capital requirements.
In other words, Taihe Water was not selling technology products but offering "technology + engineering services," earning profits from engineering activities while maintaining the image of a technology company.
2. Listing Didn't Solve Fundamental Issues; It Only Magnified Risks
When Taihe Water went public, it raised 550 million yuan to cover its operating expenses, but this only provided temporary relief:
- Fundamental Constraints of the EPC Model: Engineering projects involve working first and then receiving payment—paying for labor, materials, and subcontractors, with a cycle lasting 2-3 years. While the funds allowed the company to take on more projects, they also increased its accounts receivable and financial pressure.
- Cash Flow Crisis: In 2021, although it didn't incur a loss, its operating cash flow was negative by 128 million yuan (more expenses than revenue). By 2022, revenue plummeted, and losses began. By 2025, accounts receivable had exceeded annual revenue by more than three times, forcing the company to recognize these as bad debts.
This situation is akin to borrowing money to expand business operations only for customers to continuously default on their payments, resulting in increasing losses.
3. Disconnected Progress Elements Hindered Business Growth
Water ecosystem projects have multiple stages of completion, but Taihe Water failed to align them properly:
- Ecological Recovery: The success of aquatic plant growth and water quality depended on weather and external pollution, making it difficult to meet deadlines.
- Financial Revenue: The company recognized revenue based on costs incurred (e.g., recognizing half of the revenue when only half of the materials were used), but this required approval from the client or supervisor.
- Client Payment: If government budgets were not approved or if the main contractor did not pay, Taihe Water couldn't collect its money. As a result, many projects were completed without proper payment recognition. For example, some projects generated less than 10% of their expected revenue, and others resulted in legal disputes that further reduced earnings.
The issue was not with slow government payments but Taihe Water's inability to control the payment process; it bore the responsibility for ecological restoration without controlling the timing of client payments.
4. Mismatch between Capabilities and Business Model
Taihe Water had strong technical capabilities but weak engineering management:
- Contract Management: It failed to assess the clients' payment ability when selecting projects or negotiate proper payment terms in contracts.
- Payment Collection: It failed to promptly request client approval and payment after completing projects.
- Financial Management: With growing accounts receivable, it resorted to inventing projects and recognizing revenues prematurely to misrepresent its financial statements (which was discovered by regulators). For instance, in 2017, it recognized all revenue for a Fuzhou project before the work was completed; in 2025, it created fictitious projects. Both instances were due to an inability to determine the appropriate timing for revenue recognition.
5. Industry Lessons: The Right Approach for Water Ecosystem Companies
Taihe Water's failure is not indicative of a failing industry but rather a flawed business model. In the future, water ecosystem companies will likely divide into two categories:
- Engineering Focus: Those that continue with EPC projects but require strong capital and project management skills (selecting appropriate projects, negotiating payments, and managing subcontractors).
- Technology Focus: Those that develop their technology into standardizable products (e.g., equipment or process packages) or provide long-term operational services (charging based on water quality outcomes), thereby shortening the payment cycle.
The key is to avoid using a technology company's approach to acquire projects while assuming the risks associated with an engineering firm. Technology is a valuable asset, but success depends on the ability to collect payments.
Conclusion
Taihe Water’s story highlights that while technology can improve water quality, it is essential to manage contracts, cash flows, and project execution effectively to sustain a business. Environmental companies should not be misled by their technological credentials; they must clearly understand whether they are providing technology or engineering services and ensure their capabilities match the nature of their business.
