Regulations about safety of hydraulic engineering constructions

Chapter 1. General provisions

1. These Regulations about safety of hydraulic engineering constructions (further – Regulations) are developed according to Item 2 of article 70 of the Water code of the Republic of Kazakhstan (further – the Code) and determine types of the hydraulic engineering constructions (further – GTS) carried to potentially dangerous constructions requirements for their safety imposed to designing, construction, operation, reconstruction, preservation or liquidation.

2. In these Regulations the following basic concepts are used:

1) To – diagnostic value of technical performances of the criteria measured in process of monitoring of technical condition of GTS;

2) K1 – the controlled level of criteria value in case of which achievement stability, the mechanical and filtrational durability of GTS and its basis, and also handling capacity of water waste and water throughput constructions still correspond to conditions of normal operation;

3) K2 – the controlled level of criteria value in case of which exceeding operation of GTS in the project modes is inadmissible;

4) accident of GTS – partial or final fracture of GTS, equipment failure as a result of which the construction becomes disabled and can arise emergency situation;

5) emergency – danger of emergence of accident of GTS as a result of the external impacts which are not provided by the project, decrease in operability of construction or its basis as a result of change of properties of materials of construction or soil of the basis or decrease in reliability of the hydromechanical equipment, and also as a result of decrease in water handling capacity of constructions as for technical reasons, and in connection with restrictions under the terms of the admissible water mode of waterway below alignment of constructions;

6) the declaration of safety of GTS – the main document in which safety of GTS is proved is established GTS compliance to criteria of safety taking into account its class and the list of necessary works on safety of GTS is determined;

7) class GTS – the indicator established by regulations and rules of designing of GTS depending on which requirements to reliability of GTS are established;

8) preservation of GTS - complex of the project and construction works performed for the purpose of temporary preserving GTS and ensuring its safety in the conditions of the omission of transit expenses without regulation of the water mode with the corresponding decrease in water level in water storage basin;

9) liquidation - complex of the project and construction works performed for the purpose of complete disassembly of GTS and recovery of the natural water mode and bed of waterway which are not creating obstacles in case of the omission of flood.

10) inspection of GTS - complex of actions for assessment of technical condition and operability of GTS, and to determination of the list of necessary works on ensuring reliability and safe operation of these constructions.

Chapter 2. The types of hydraulic engineering constructions carried to potentially dangerous

3. Depending on characteristics and degree of potential danger for the environment and life activity of the person of GTS are distributed on danger classes according to the procedure from the highest to the smallest.

4. Treat GTS I of class of danger:

1) dikes more than thirty meters high and (or) water storage basin amount more than hundred million cubic meters;

2) water-engineering systems with handling capacity more than hundred cubic meters per second.

5. Treat GTS II of class of danger:

1) dikes more than twenty meters high and (or) water storage basin amount more than fifty million cubic meters;

2) water-engineering systems with handling capacity more than fifty cubic meters per second.

6. Treat GTS III of class of danger:

1) dikes more than ten meters high and (or) water storage basin amount more than twenty million cubic meters;

2) water-engineering systems with handling capacity more than twenty cubic meters per second.

7. Treat GTS IV of class of danger:

1) dikes more than five meters high and (or) water storage basin amount more than ten million cubic meters;

2) dikes up to five meters high and (or) water storage basin amount less than ten million cubic meters, in cases if destruction of these GTS can do harm to life, health of the person and the environment;

3) water-engineering systems with handling capacity to ten cubic meters per second, in cases if destruction of these GTS can do harm to life, health of the person and the environment.
