The construction of Smart Water Affairs takes big data application as the core. According to the construction needs of the main contents of each smart water affairs application, and to meet the requirements for storage, sharing, and analysis-mining of massive and heterogeneous big data, it should comprehensively satisfy the storage, processing, and computing requirements of structured, semi-structured, and unstructured data. At the same time, to meet the overall construction needs of the big data platform, it should provide access capabilities for various data sources; after data reception, it should provide distributed batch computing processing and streaming real-time computing processing frameworks, as well as data mining, analysis, and presentation capabilities. Therefore, the creation of intelligence is itself a full-life-cycle process of data resource application. Thus, the overall construction of a smart city is likewise premised on building "big data core capabilities".

Water data resources underpin water big data development. We enhance data acquisition, integrate multi-source water data, build a water data catalogue and optimize update mechanisms to deliver a standardized, continuously updated water data system.
1. Boost data acquisition capacity. Optimize data planning and responsibilities to eliminate redundant collection and achieve "collect once, reuse many times". IoT and mobile Internet expand collection channels, standardize transmission and guarantee timeliness and security.
2. Consolidate water data resources. Integrate basic, business, management, achievement and statistical data to form well-arranged, secure and eco-efficient water data assets for unified management and utilization.

The command center is an important place for water affairs management departments to carry out emergency duty and command dispatching. The command center integrates various business systems, connects with emergency linkage units, accesses on-site images of accidents, and provides communication services such as audio-video consultation and communication dispatching, realizing functions such as comprehensive research and judgment, collaborative consultation, emergency decision-making, command dispatching, and task assignment, thereby establishing a modern water affairs command system.
