    Decision Support System for Emergency Disposal of Sudden Water Pollution in Middle Route of South-to-North Water Diversion Project

    Beijing, China

Project Summary

Project

The South-to-North Water Diversion Project delivers water from the Yangtze River to 53.24 million people in 18 large and medium-sized cities in China. However, due to the size of the project and its route through urban areas, traditional emergency response plans were not enough to effectively respond to sudden water pollution accidents, such as tanker spills and pipe breaks, and ensure safety. Henan Water & Power Engineering Consulting was tasked with developing a system to improve water pollution emergency planning and response along the middle route of the project, which stretches for 1,432 kilometers.

Solution

Henan Water & Power Engineering Consulting determined that the best solution would be a BIM model of the entire middle route. The organization used unmanned aerial vehicles (UAVs) to gather image data of the waterway, sluice gates, bridges, buildings, and other details of the surrounding environment. These images were then used to create a digital model. Within that digital model, the design team created a hydraulic model that displayed water quality, as well as the size and extent of actual or potential pollution events.

Outcome

Henan Water & Power Engineering Consulting finished modeling the entire middle route in just two months. With the decision support system now active, officials have strong 3D visualizations of the waterway and the ability to plan for various pollution scenarios. All stakeholders receive up-to-the-minute water quality data during pollution events, speeding decision-making for remediation. The decision support system now helps officials save an average of CNY 3 million when responding to each instance of water pollution.

Software

ContextCapture managed the large amount of high-quality image data gathered by UAVs and created a reality mesh that formed the basis of the digital twin. MicroStation and OpenBuildings Designer helped the design team create models of channels, bridges, buildings, and other features within the digital twin. ProjectWise established an open, connected data environment that allowed designers to easily collaborate.

Outcome/Facts
  • Due to the size and urban route of the South-to-North Water Diversion Project, traditional water pollution response plans were not enough to ensure safety.
  • Henan Water & Power Engineering Consulting created a digital model of the 1,432-kilometer middle route in only two months.
  • Using the 3D model to visualize the hydraulic data, stakeholders can make faster decisions during instances of water pollution.
  • The decision support system now helps officials save an average of CNY 3 million when responding to each instance of water pollution.
Quote:
  • “The tools provided by Bentley are able to share data and coordinate between UAV reality modeling, GIS technology, and water modeling. This project is an important example of the integrated application of BIM technology and state-of-the-art information technology and provides the government with a decision-making system based on 3D visualization.”
