Securing the Crivina Dam
The safety enhancement project for the Crivina–Ogrezeni intake dam—a strategic structure vital for the potable and industrial water supply of Bucharest—aimed primarily to increase the operational safety of the hydrotechnical works, reduce risks associated with potential structural failures, and ensure the protection of downstream populations, property, and the environment.
The implementation of proposed measures—including the construction of Dissipation Step IV, a mobile berm, and channel bed development works downstream—contributes to restoring the reservoir’s safety parameters in accordance with current technical regulations. These interventions ensure sustainable and predictable operation of the hydrotechnical infrastructure.



Operation Regulations for the Săcele Dam and Reservoir
Initial Phase (1971–1976)
AQUAPROIECT SA contributed to the technical development of the Săcele Dam, commissioned in 1976 to supply water to the city of Brașov. The subsequent increase in retention level optimized storage capacity and supported urban development.
Elevation Works (1994–2019)
Through design and engineering expertise provided by AQUAPROIECT, the dam was elevated by 5 meters, with the work completed in 2019. The result: increased capacity and safer operation, tailored to contemporary demands.
Updated Operation Regulation (2024)
In 2024, AQUAPROIECT prepared an updated operation regulation, incorporating measures to protect downstream areas and ensure efficient and safe dam operation.

Dam Incident Response Plans for Porțile de Fier II
The action plans for dam accidents in Romania are updated periodically, once every 10 years, in accordance with national operational safety legislation. The Iron Gates I and Iron Gates II dams are the most important and complex hydraulic structures in the country, playing a strategic role in energy resource management. They are jointly operated in cross-border cooperation with the Republic of Serbia.
The specific action plan for these dams thoroughly analyzes the risks and potential effects of a major accident that could occur on the Danube River. It highlights the devastating impact of the resulting flood wave and includes flood hazard maps, precise modeling of flood wave propagation, and detailed evacuation measures for each downstream locality at risk.


Improving the safe operating conditions of the Leșu Reservoir
Located in the Iad Valley, Bihor County, the Leșu Dam is situated in an area of high ecological importance, within the Natura 2000 protected sites. In this context, the works required a responsible approach and solid technical expertise.
With extensive experience in hydraulic engineering, AQUAPROIECT SA designed and coordinated the necessary interventions to enhance the safety of the dam. The works included:
- Dewatering and waterproofing the upstream face with geomembrane;
- Repairs to the facing and foundation ground;
- Rehabilitation of galleries and hydromechanical equipment;
- Sealing through injections and upgrading the monitoring systems;
- Environmental protection measures such as a fish ladder, floating islands, and maintenance of ecological flows.
The result: a reinforced, durable, and safe reservoir
Through meticulously executed works under the coordination of a highly experienced team, AQUAPROIECT SA contributes to the continued functionality and safety of the Leșu Dam — a strategic objective for regional water resource management and for protecting downstream infrastructure.
