Before the rainstorm strikes, the local river should be treated in advance, and at the same time, the water level of the river should be checked. If there is a problem with the river, it can be dealt with by digging and expanding the river. Only by ensuring the good water circulation performance of the river can we effectively ensure that there will be no urban waterlogging after the arrival of heavy rain.

02, need to transform the underground pipe network.

In fact, the main reason for urban waterlogging is the poor drainage performance of underground pipelines. Then in this case, the diameter of the pipeline should be appropriately increased. In addition, it is also possible that the problem of rain and sewage diversion has not been solved, so there will be urban waterlogging. To solve this problem, rain and sewage must be separated, which requires planning in advance.

03. Drainage facilities can be added.

Drainage facilities in some cities are insufficient. When the rainfall is heavy, the drainage speed will be slow. In this case, drainage facilities can be increased, such as building drainage tidal gate and building some drainage pumping stations.

04, the storage capacity can be increased.

In the face of heavy rain, if the city has strong storage capacity, then there will naturally be no waterlogging. For example, we can build some large reservoirs or plan some large water storage lakes.

05, can increase the permeability.

If the infiltration capacity is strong, then the rain will definitely penetrate into the soil, so it is not easy to get waterlogged. The common way is to lay permeable pavement or concave green space.

06, rainy days timely send water personnel to inspect.

When the city is faced with heavy rain, the relevant departments must organize personnel to conduct inspections in time, especially those cities with serious waterlogging. This step is essential. When serious water accumulation is found in a certain area, it is necessary to come up with a solution in time.
