1. Hygienic problems: Clogged sewers will prevent sewage from being discharged smoothly, and a large amount of sewage will accumulate in the house. This will not only create a bad smell and bacteria breeding environment, but also bring potential risks to the health of residents.
2. Structural safety: A large amount of accumulated water will cause damage to the structure of the house, especially to the floor, walls and foundation. Long-term water accumulation will lead to problems such as wall seepage, floor deformation and foundation settlement, which will further affect the structural stability of houses.
3. Electrical safety: A flooded house in Jinshan will lead to water ingress of wires and electrical equipment, increasing the risk of electric shock. This poses a threat to the safety of residents.
