What are the negative risks if the drainage ditch is not cleaned in time?
1. Flood disaster: The blocked drainage ditch will lead to the failure of rainwater drainage in time, which will lead to flood disaster. Rainwater will accumulate on the road surface and form a deep water area in heavy rain weather, which will bring potential safety hazards to pedestrians and vehicles.
2. Sewage backflow: The blockage of drainage ditches will lead to sewage backflow, and sewage will flow back to low-lying places, polluting the environment and affecting the quality of life of residents.
3. Disease spread: The blockage of drainage ditches will lead to sewage retention, breed various bacteria and viruses, and easily lead to the spread of diseases, such as cholera and dysentery.
4. Road damage: The blockage of drainage ditches will cause rainwater to accumulate on the road, and long-term water accumulation will erode the road, causing road damage and increasing urban maintenance costs.
5. Environmental pollution: The blockage of drainage ditches will lead to sewage retention, pollute the environment and affect the urban ecological environment.
Therefore, it is very important to dredge the drainage ditch in time, which can effectively avoid the above negative risks. At the same time, we should also strengthen the management and maintenance of drainage ditches to ensure the smooth flow of drainage ditches and the normal operation of the city.
