Water supply and drainage —— Exploring the issue of sewage backflow caused by heavy rainfall
Thread Content
Modern cities are developing at a rapid pace, with their urban areas expanding continuously. Coupled with the reduction in green spaces and the increase in paved surfaces, heavy rains often lead to rainwater or even sewage backing up, causing flooding in residential areas and resulting in significant material losses and public dissatisfaction. How should responsibility for this be allocated? Everyone can share their opinions
To thoroughly implement the separation of rainwater and sewage, it is necessary to supervise sewage discharge control at the source (i.e., among enterprises), and mixing of rainwater and sewage must be strictly prohibited.
This phenomenon also exists in factories. It is mainly due to inadequate design considerations: there is no separation between cleaning and purification processes, and the processing margin is insufficient. Only consider how to reduce the initial investment.
