- Abstract:
- Based on the practice of an interconnected “water plant-pipe network” system and long-term water quality monitoring data, this paper taking Ningbo as a case study, systematically discusses the construction pathway and practical outcomes of transforming the urban water supply system from “passive security” to “active adaptation”. It has established a three-tier ring-shaped water supply structure-comprising a “regional water supply expressway, backbone distribution loops within subareas, and dual-path water supply security for grid units”-centered on the interconnection of five water plants in the central urban area, significantly enhancing the resilience of the water supply system. The whole-process water quality safety is guaranteed relying on high-quality raw water and advanced treatment technologies such as ultra-filtration membranes. Through operational practice, an internal control standard for drinking water manganese concentration (≤0.005 mg/L) has been developed and implemented within the enterprise since September 2018, effectively suppressing the “yellow water” phenomenon in the pipe network. Taking the smart water management platform as the carrier, a data-driven early warning, dispatching, and decision-making mechanism is implemented. Through this, the case of data asset credit financing based on insured and unsecured claims in the country is accomplished, thereby achieving dual-drive advancement through “technology empowerment and data value enhancement”.
