随着社会发展,人民物质文化生活水平的不断提高,人口和工商业向城镇集中,城镇化使得工、商业高度集中,固定资产积累直线上升,人口日益密集,防洪除涝越显重要。城区排水系统不仅发挥着排出城市生活污水和工业废水的重要作用,还担负着除涝的重要任务。必须对城区排水系统合理规划,科学治理,使城市排水系统与城区防洪除涝、城市发展相一致。
With the development of society, people’s material and cultural living standards continue to increase, and population and commerce and industry converge on cities and towns. Urbanization has led to a concentration of industry and commerce, a steady rise in fixed assets, and an increasingly dense population. Flood prevention and waterlogging are even more important. The urban drainage system not only plays an important role in discharging urban domestic sewage and industrial wastewater, but also shoulders the important task of removing waterlogging. The urban drainage system must be properly planned and scientifically managed to make the urban drainage system consistent with urban flood control and waterlogging prevention and urban development.
