Smart Water Solutions

Background Introduction

1. The water quality at source areas is cause for concern; in some regions, water supply capacity is inadequate, leakage and losses are severe, and non-compliant water quality is a prominent issue. There is an urgent need to develop smart water management systems and to improve water supply, water use, and water allocation infrastructure.

2. In some Chinese cities, persistent heavy rainfall or abnormal weather conditions during the rainy season can trigger urban flooding, jeopardizing the safety of people’s lives and property. To mitigate this risk in the future, it is necessary to develop hydrodynamic infrastructure and intelligent water-management systems, thereby creating a sustainable drainage environment and effectively reducing the likelihood of urban flooding.

3. With the continuous development of China’s socialist market economy, demand for various resources and energy has also increased. The exploitation of water resources has further exacerbated water pollution, making it imperative to implement water-environment remediation projects through in-stream source control, shoreline enhancement, ecological restoration, and other measures.

4. The level of informationization in traditional water utilities in Chengdu is relatively low, with implementation limited to conventional business process management. Although a foundational database has been established, a substantial amount of data still requires manual processing, and there are no intelligent, IT-driven tools for batch integration and in-depth analysis of massive datasets. There is an urgent need to leverage new technologies to enhance the efficiency and effectiveness of water utility management, enabling comprehensive sensing, automated control, and data-driven decision-making.

Establish a “one river, one map, one strategy” framework and build an automated, information-driven, and digital smart water management platform.

3. Leverage intelligent and information-based technologies to comprehensively enhance the water authorities’ governance and control capabilities, providing efficient and convenient regulatory tools while furnishing a scientific and reliable decision-making basis for day-to-day management operations.

FEATURES OF THE SOLUTION

 

System Composition

Smart Water Environment:

1. Hydrological monitoring is designed for real-time measurement of hydrological parameters—including water level, flow rate, flow velocity, precipitation (including snowfall), evaporation, sediment load, ice cover, soil moisture, and water quality—in rivers, streams, lakes, reservoirs, canals, and groundwater within the jurisdiction of the managing authority. The hydrological monitoring system utilizes wireless communication to transmit monitoring data in real time, thereby significantly enhancing the operational efficiency of hydrological agencies.

2. Meteorological monitoring involves the fixed-point, continuous, or timed sampling and measurement of pollutants present in the atmosphere. To monitor air quality, several air-monitoring stations are typically established throughout a city, equipped with automated monitoring instruments for continuous, automatic data collection. The monitoring results are then periodically retrieved by personnel, analyzed, and used to generate relevant datasets.

3. Deformation monitoring: Utilize an integrated inclinometer to monitor structural changes in hydraulic, urban, and natural slope and mountainous areas, including displacement, micro-deformations, collapses, and landslides.

4. Water quality monitoring is the process of assessing whether water quality meets environmental protection and human health standards by detecting and analyzing pollutants in water bodies. Commonly used monitoring parameters include dissolved oxygen, pH, chemical oxygen demand, total nitrogen, and total phosphorus. Water quality monitoring enables an understanding of the pollution status of water bodies and facilitates the timely implementation of appropriate measures for pollution control and source protection.


Smart Water Management:

Smart hydraulic gates are high-tech products that integrate intelligent, automated, and remote-control technologies. By leveraging sensors, monitoring systems, and cloud platforms, they enable precise measurement and real-time data transmission of parameters such as water level, flow rate, and temperature, thereby facilitating intelligent control and management of the gates.

Smart pipeline networks primarily provide remote monitoring of parameters such as pressure, flow rate, temperature, and water level in water supply and drainage networks.
