According to the Beijing Drainage Group, based on the heavy rainfall forecast by the Taipei Meteorological Observatory, the group has re-mobilized, re-deployed, re-inspected and re-implemented flood prevention work, and is actively preparing for this heavy rainfall. Currently, the group is responding at level 4, and all flood prevention personnel are on standby at the base.

Beijing Drainage Group said that at 12:40 on August 16, the central city had heavy rainfall, and the group launched the fourth-level flood control response in advance. A total of 168 flood control units and 1,676 personnel were dispatched to deal with two waterlogging and circuit breaker incidents at Meishikou East Road and Jintai Bridge, and the circuit breaker time did not exceed 1 hour. "At present, the group is in accordance with the fourth-level response, and all flood control personnel are on standby at the base point." The relevant person in charge of Beijing Drainage Group pointed out that the group strictly follows the "one point one policy" and "one bridge one policy" flood control and rescue emergency plans, and implements emergency measures such as early deployment of units and pre-placement of water pumps. In case of extreme weather conditions, further strengthen the deployment and guard of sunken bridges with high drop, and carry out emergency disposal in a timely manner.

It is understood that in response to this rainfall, Beijing Drainage Group inspected and cleaned 697 rainwater outlets and 4.2 kilometers of rainwater pipelines around all 157 sunken bridges, 78 flood risk points and other key areas before the rain. After the rain, it conducted inspections of other areas, carried out cleaning and maintenance in a timely manner, and ensured the normal operation of facilities during the rainy period.

At the same time, the water pumps, water inlet and outlet pipelines, backup power supplies, and various monitoring systems of 87 rainwater pumping stations were rechecked and re-inspected; the initial pool and storage pool were emptied in advance. 38 pumping stations powered by overhead lines were sorted out, and they were connected with the power supply bureau to prepare for emergencies such as power outages. Second, the equipment and vehicle inspections of the 252 flood control units were completed, and spare parts were replenished and generator fuel was filled. Third, all rainfall stations, vehicle-mounted videos, and bridge area videos were inspected, and all equipment was operating normally.

In addition, in accordance with the plant-network integrated operation guarantee model, 17 recycled water plants pumped large amounts of water ahead of schedule at 8:00 on August 16, reducing the liquid level pressure in the upstream pipelines, freeing up 30,000 cubic meters of capacity for the pipeline network.

The above-mentioned person in charge also revealed that they have completed the connection with the river department, all the river outlet gates have been opened, and the river liquid level and dam information have been shared in real time; they have completed the connection with the traffic control and transportation departments, and assisted in coordinating traffic interruptions and navigation measures; they have connected with the sanitation and street departments to implement the linkage of rainwater outlet salvage and water sweeping in the rain; they have completed the point-to-point connection with all 250 subway stations, and promptly dealt with stagnant water around the subway stations.

In response to the secondary disasters of road collapse that may occur frequently during and after rain, the Group organized to strengthen facility inspections to promptly discover potential collapse hazards. Three engineering rescue teams were arranged to be on duty 24 hours a day at the base points to prepare in advance and be ready to go at any time to quickly deal with road collapse incidents caused by drainage pipe networks.

In the next step, the group will maintain close contact with the municipal meteorological observatory, grasp the latest weather conditions, dispatch flood prevention personnel in a timely manner according to the flood situation, and make every effort to deal with this heavy rainfall.
