Customers
CDT sells primarily to municipal end markets in China, where local governments and public utilities need wastewater infrastructure and ongoing plant operations. It also serves industrial and other infrastructure customers that require treatment systems, turnkey project delivery, and long-term operating support. The business model depends on customers that value complete engineering solutions rather than stand-alone equipment purchases.

Strategy
CDT’s strategy centers on using its wastewater engineering base to win municipal projects and deepen long-term customer relationships through operations and maintenance. The company also highlights strategic partnerships and a new energy development direction linked to China’s dual-carbon goals, which can broaden its addressable market beyond core sewage treatment work. Backlog and project bidding remain important to near-term execution because the business is project-led and depends on converting pipeline opportunities into contracted work.
Project awards drive equipment, installation, and service revenue in a project-led market.
Operations and maintenance can stabilize revenue versus one-time project delivery.
Adjacencies can diversify the revenue base and reduce dependence on one end market.
Geography
CDT’s business is concentrated in China, with headquarters in Shenzhen and project activity across the country. The company states that it has completed more than 150 plants in China, indicating a nationally distributed operating footprint rather than one single local market. Its exposure is therefore tied to Chinese municipal spending, environmental regulation, and regional project execution conditions.
Risks
CDT is exposed to project concentration, because wastewater businesses often rely on a limited number of municipal contracts and timely project execution. It also faces policy, funding, and competitive risks tied to Chinese infrastructure spending and environmental regulation, while its U.S.-listed structure adds capital markets and compliance sensitivity. As a project-and-service business, delays, cancellations, or weak bid conversion can materially affect revenue timing and backlog conversion.
