The United Arab Emirates (UAE) is known for its rapid development and ambitious infrastructure projects. The construction of high-rise buildings, artificial islands, and agricultural development require solving numerous engineering problems, among which groundwater control plays an important role. In conditions of hot climate and limited water resources, groundwater level management becomes a key factor for the successful construction and operation of facilities. In this article, we will consider when and why is required Dewatering Dubai.
Features of groundwater in the UAE
The UAE has a diverse geology, with sand dunes, salt flats, rocky deserts and coastal areas. Beneath these surface layers are underground aquifers, the level of which can fluctuate significantly depending on natural and anthropogenic factors. In some areas, groundwater is close to the surface, which causes problems during construction and operation of facilities.
The problem of groundwater control in the UAE is exacerbated by the specifics of the local climate: minimal rainfall and high temperatures lead to rapid evaporation of moisture. However, in coastal and low-lying areas, groundwater levels can remain high due to capillary rise of water, which leads to the creation of unfavorable conditions for the construction and operation of infrastructure.
When is groundwater pumping required?
Groundwater pumping in the UAE is necessary in several key cases:
- Preparing construction sites
When building skyscrapers, underground parking lots, tunnels and other large structures, pumping out water is a must. Groundwater can significantly complicate the work of excavators and other construction equipment, increasing the risk of pit collapse and flooding at the construction site. Preliminary pumping reduces these risks and ensures safe working conditions. - Construction and operation of underground facilities
In cities such as Dubai and Abu Dhabi, where underground parking lots, metro tunnels and underground shopping malls are becoming commonplace, it is necessary to regularly maintain the groundwater level at a low level. To do this, drainage systems and pumps are installed to ensure constant water pumping. - Elimination of flooding and improvement of soil stability
In low-lying areas, where groundwater is close to the surface, pumping is required to prevent flooding of buildings and roads. High water levels can lead to foundation degradation, destruction of road surfaces and other negative consequences. In addition, excessive soil moisture reduces its bearing capacity, which is dangerous for massive buildings and structures. - Agriculture and Landscape Design
The UAE is actively developing agriculture despite its arid climate. In oases and other farming areas, groundwater management is important to optimize irrigation and prevent soil salinization. Pumping is also necessary to maintain the desired microclimate and protect plant root systems from excessive moisture.
Methods of pumping and monitoring groundwater
The UAE uses advanced technologies and equipment for pumping groundwater:
- Drainage Wells and Vertical Pumping Systems
Drainage wells are drilled at construction sites and in areas with high groundwater levels. They are connected to pumps that effectively remove water from the underground layers. - Horizontal drainage systems
Drainage pipelines are laid along sections of roads and around underground objects, through which water flows into special reservoirs or is diverted into sewer systems. - Modern sensor and monitoring systems
To prevent emergency rise of groundwater, sensors are used that monitor the water level in real time. When critical levels are reached, the system automatically activates the pumps. - Desalination and Water Reuse Systems
Water resources in the UAE are extremely valuable, so a significant portion of pumped water passes through treatment systems and is reused for industrial purposes or irrigation.
Conclusion
Groundwater management and pumping in the UAE is an integral part of the successful functioning of the economy and maintenance of infrastructure. High groundwater levels can be an obstacle to the implementation of large-scale construction projects, but thanks to advanced technologies and an integrated approach, the UAE successfully solves these problems. Groundwater management allows the country to develop effectively, creating comfortable and safe conditions for living and doing business.
