China News Service, March 29, according to the "China Water Conservancy" WeChat official account, in order to implement the spirit of the National Water Conservancy Work Conference, anchoring "no casualties, no reservoir collapse, no breach of important embankments, and no impact on important infrastructure" "The goal is to make every effort to ensure the safety of reservoirs during floods. The Ministry of Water Resources recently issued a notice requiring that the reservoirs be safely used for floods in 2024.
1. Improve the responsibility system for reservoir and dam safety
All provincial water administrative departments and river basin management agencies must strictly follow the relevant provisions of the "Regulations on Reservoir and Dam Safety Management" and the relevant requirements of the "Notice of the General Office of the Ministry of Water Resources on Implementing the Persons Responsible for Reservoir and Dam Safety in 2024" The reservoir and dam safety responsibility system with the government chief executive responsibility system as its core clearly defines the government responsible person, the responsible person of the reservoir competent department, and the responsible person of the reservoir management unit. The person in charge of the government assumes leadership responsibility for the safety supervision of reservoirs and dams, and coordinates and solves major safety issues of reservoirs and dams in a timely manner; the person in charge of the reservoir management department supervises and guides the reservoir management unit to implement various safety measures; the person in charge of the reservoir management unit does a good job in the daily operation management of the reservoir and maintenance work, and strictly implement dispatching instructions to ensure the safe operation of the project.
2. Implement “three responsible persons” for small reservoir flood control
All provincial water administrative departments must follow the "Notice of the General Office of the Ministry of Water Resources on Issuing the Duty Performance Manual of the "Three Responsible Persons" for Small Reservoir Flood Control (Trial) and the "Three Key Links" Work Guide for Small Reservoir Flood Control (Trial)" Requirements to fully implement the "three responsible persons" for flood control administration, technology, and inspection of all small reservoirs within the jurisdiction. It is necessary to urge the responsible person to log in to the website of the Operation and Management Department of the Ministry of Water Resources (yxgl.mwr.gov.cn) and participate in online training in the "Training of Three Persons Responsible for Small Reservoir Flood Control" column to strengthen safety awareness, establish a firm bottom-line thinking, and ensure that all floods are completed during the flood season. Get the job done. The Ministry of Water Resources will update and improve the training courseware according to the new situation and new requirements. The administrative person in charge coordinates and solves major reservoir flood control safety issues in a timely manner, and organizes emergency response and personnel transfer and avoidance when danger occurs; the technical person in charge strengthens the technical guidance of reservoir flood control work, is responsible for information submission and updating, and organizes the verification and approval of reservoir information files. ; The person responsible for inspections should be on duty during the flood season, strengthen inspections, and ensure that dangerous situations are discovered, reported, and handled in a timely manner.
Third, ensure dangerous reservoirs to survive floods safely
Provincial water administrative departments and river basin management agencies must accurately grasp the safety status of the project, formulate and implement measures to restrict the use of dangerous reservoirs on a reservoir-by-reservoir basis, and follow the relevant provisions of the "Emergency Notice of the General Office of the Ministry of Water Resources on Efforts to Prepare Reservoirs for Safe Flood Control" According to the requirements, in principle, dangerous reservoirs should be operated empty during the main flood season. It is necessary to urge the project legal person to implement the primary responsibility for the safe flood relief of the risk removal and reinforcement project, establish and improve the responsibility system of all parties involved in the construction, scientifically prepare flood control plans, strengthen safe flood relief measures, and make solid on-site flood preparedness, flood situation notification and emergency response, etc. Work.
4. Strengthen reservoir safety management
Provincial water administrative departments and river basin management agencies must improve pre-flood inspection mechanisms and increase the investigation and rectification of hidden dangers in key parts such as reservoir dams, spillways, and venting facilities. It is necessary to strengthen the prevention and control of termites and other harmful animals, and realize the institutionalization, professionalization and normalization of prevention and control work. It is necessary to improve reservoir dispatching procedures (plans) and dam safety management (flood control) emergency plans on a reservoir-by-reservoir basis, strictly implement approval and reporting procedures, strengthen training and simulation exercises, and effectively improve pertinence and operability. It is necessary to speed up the construction of small reservoir rainwater forecasting and dam safety monitoring facilities, vigorously promote the construction of monitoring platforms, strengthen the collection and application of monitoring information, and improve the level of reservoir monitoring and early warning. It is necessary to gradually improve the reservoir's flood control transportation, communications, alarm, lighting and other management facilities, continuously improve the reservoir safety management capabilities, and provide basic guarantee for the reservoir's safety during floods.
5. Implement emergency response measures
Provincial water administrative departments and river basin management agencies should strengthen rainfall forecasts and flood early warnings, and send early warning information directly to the front line, directly to reservoir management units, and directly to the person responsible for reservoir safety. It is necessary to strengthen inspections and defenses and emergency protection in dangerous situations, increase the frequency of inspections and monitoring of extreme weather, report signs of danger immediately, issue early warnings to relevant downstream areas, and quickly organize the transfer of threatened people to ensure the safety of people's lives. It is necessary to ensure that emergency rescue forces and materials are in place, and to organize timely rescue and rescue operations for dangerous situations such as flood tops, landslides, dam body cracks, collapse, leakage, and piping surges during the flood season, especially during heavy rains. It is necessary to scientifically formulate and implement measures to prevent dam collapse due to excessive floods based on the actual conditions of the reservoir. Emergency measures such as setting up emergency spillways or other flood discharge facilities, taking emergency measures such as rushing to build sub-dykes, spreading colorful strips, and digging temporary flood discharge channels are needed to strictly prevent dam collapse events. .
Sixth, strengthen the safety management of reservoir storage capacity
Provincial water administrative departments and river basin management agencies must follow the relevant requirements of the "Guidance Opinions of the Ministry of Water Resources on Strengthening Reservoir Capacity Management" to promptly investigate the siltation and encroachment of drainage reservoirs, and respond to serious siltation and encroachment problems or the occurrence of high-sand floods. For reservoirs that suffer from landslides, bank collapses, etc. in the reservoir area, storage capacity calculations and storage capacity curve reviews will be carried out on a reservoir-by-reservoir basis. It is necessary to strengthen the safety management of storage capacity, strengthen the supervision of the use of the reservoir area, and do a good job in rectifying outstanding problems to ensure the safe operation of the reservoir and the full realization of the benefits of flood control.
7. Do a good job in submitting information
Provincial water administrative departments and river basin management agencies must dynamically monitor the progress of various reservoir safety flood relief tasks and submit information in a timely manner through the National Reservoir Operation Management Information System. Before April 30, 2024, the "three responsible persons" for reservoir dam safety and small reservoir flood control will be fully implemented. Before May 31, 2024, the training of the "three responsible persons" for small reservoir flood control, the implementation of restricted use measures for dangerous reservoirs, the improvement and approval of reservoir dispatching procedures (plans) and dam safety management (flood control) emergency plans will be completed. Before June 30, 2024, the review of storage capacity curves of large and medium-sized reservoirs tasked with flood control will be fully completed.
Provincial water administrative departments and river basin management agencies must strengthen organizational leadership, effectively perform regulatory responsibilities, increase supervision, and strictly follow time requirements to complete various tasks for safely handling floods. The Ministry of Water Resources will conduct on-site surveys, telephone spot checks, etc. to promptly understand and regularly report the implementation status of reservoir flood control measures. If a reservoir is in danger of overflowing or a dam collapses, the investigation and handling will be strengthened and the responsibilities will be strictly investigated in accordance with the "Opinions of the Ministry of Water Resources on Strengthening the Investigation and Handling of Reservoir Dam Overflows and Dam Collapses".
