Nansha will investigate the "black spots" in the area in the region to eliminate the risk of waterlogging

On July 25, the feasibility study, preliminary design and survey projects began to bid for feasibility research, preliminary design and survey projects in Nansha District. Basically eliminate the risk of waterlogging at the existing hidden danger.

Local location drainage facilities are still imperfect

In the bidding announcement, although most areas of Nansha have built a complete municipal drainage pipeline system, there are still imperfect situations in the local location drainage facilities. The water mouth cannot be constructed to form a broken tube, and some pipe sections have been artificially destroyed and blocked, and the current drainage pipeline system is broken or sinking due to the uneven depression of the foundation. Local low -lying areas occur during flooding during the rainstorm.

Basically eliminated the risk of waterlogging before the end of 2025

In the bidding announcement, it was proposed that the water -immersed black spots in the entire area of ​​Nansha District, the overall analysis of the rain and the sewage system of the water soaking black spots, and the renovation of some current rainwater pipe networks in the Nansha area, significantly improved the scope of engineering transformation. The design reappearance period and overcurrent capacity of the surrounding pipe network of the inner waterlogging point. When rainfall within the design standard of the urban rainwater pipe network, "water accumulation" and above should not occur in the corresponding area.

Actively review and investigate hidden dangers such as low construction standards in the current situation of rainwater pipelines in Nansha District and no downstream rainwater pipes in order to further systematically solve the problem of urban drainage and ensure that the safety of drainage and urban development is consistent with the coordination of urban development. Take the remedy of rainwater pipe restoration of the gravity, storing, storage, or serious structural hidden dangers of the new rainwater pipe (canal) of water pipes (canal) in Nansha District restored and improved the status of rainwater discharge of water in the black spots. In order to further strengthen Nansha Divide water immersion in the area. By the end of 2025, the risk of waterlogging at existing hidden dangers is basically eliminated.
