1. Flood control facilities: A series of flood control measures and water conservancy facilities have been adopted in the planning and construction of Pingjiang New Town. For example, drainage systems, ditches, rainwater collection ponds, etc. Set around the building to ensure rapid drainage during the rainstorm and reduce the risk of water accumulation.
2. Reservoir and waterway management: Suzhou has a corresponding reservoir and waterway management system to regulate and control the water flow during rainfall. These reservoirs can store and divert a large amount of rainwater to reduce the pressure of water flow in Pingjiang New Town and other urban areas.
3. Topography: The topography of Pingjiang New Town is conducive to the rapid drainage of rainwater. If the terrain is relatively flat and higher than the surrounding water bodies, rainwater will easily flow into the drainage system or naturally drain into nearby rivers, lakes and other waters.
