China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

Ecological and Environmental Authorities / Competent Departments
Government Departments such as Water Resources and Marine Affairs
Construction of a Three-Dimensional Perception Network
Integrate existing automatic monitoring stations, discharge outlets, and various data from the meteorological and hydrological fields. Deploy IoT devices such as water quality monitoring, water quantity monitoring, and video surveillance at key nodes across the region to build an integrated “space-air-ground” monitoring system, enabling real-time dynamic collection of water environment elements.
Construction of a Data Hub
Build a water environment big data center, unify data specifications and standards, integrate Geographic Information System (GIS) map functions, and complete the cleaning, fusion, storage, and visualization processing of multi-source heterogeneous data such as hydrology, water quality, and pollution sources, forming a “one map” for water environment management.
Intelligent Application Development
Deploy core business modules such as water quality early warning, pollution source tracing, river and lake health assessment, flood control and dispatch, and environmental protection ledger management. Introduce artificial intelligence algorithms for auxiliary analysis and judgment, enabling full-process digital management from monitoring and early warning to closed-loop disposal.
Operation and Maintenance Guarantee System
Establish supporting mechanisms including system security management, regular hardware inspection and calibration, software iterative upgrading, and 7×24-hour operation and maintenance response, ensuring the long-term stable operation of the platform and achieving continuous empowerment.
Solid Data Foundation
Relying on its state-owned background and years of environmental testing accumulation, it possesses CMA/CNAS dual-qualified laboratories and localized monitoring capabilities, ensuring authoritative and precise platform data sources, with a quality control system covering the entire lifecycle.
Rich Local Experience
Deeply involved in local environmental investigation and assessment projects such as those in Shunyi, it is thoroughly familiar with regional water system characteristics, pollution causes, and management pain points, and can provide customized development and service responses highly tailored to local needs.
Integrated Construction-Management-Operation
Adopts a full-chain service model of “construction + in-depth operation and maintenance” to ensure continuous system optimization and fresh, usable data, truly achieving “built once, empowered long-term.”
