Water supply studies involve the comprehensive investigation of surface and groundwater resources to meet the water needs of project areas, assessment of their potential, and analysis of possible impacts. These studies include identifying surface and groundwater resources, determining water potential, and analyzing project water demand. Additionally, water quality analysis, hydrological and hydrogeological surveys, and modeling studies are integral parts of the process.

The services we provide in this field are crucial for ensuring the secure and sustainable planning of water supply.

A significant portion of construction and mining activities is carried out below the static groundwater level, which can have major environmental impacts on groundwater resources. To manage these impacts and ensure safe working conditions, our company performs all necessary studies for dewatering operations. Dewatering is achieved by lowering the static groundwater level below the base of the excavation or to a specified target level.

To accomplish this, various dewatering techniques are used, including pumping wells, horizontal or inclined drainage wells, drainage systems, perimeter drainage channels, and dewatering tunnels. Hydrogeological modeling is conducted to select and optimize the most suitable techniques. Additionally, monitoring and performance evaluation of dewatering operations are crucial for ensuring the success of the process.

All types of project implementations have some level of impact on natural systems. Therefore, assessing the potential impacts of planned activities on surface and groundwater systems is essential. As a company, we conduct site-specific evaluations and provide scientific and technical solutions in compliance with national and international standards to identify potential impacts and develop mitigation measures.

To meet groundwater demand and minimize potential impacts on groundwater systems, we prepare management plans that outline the necessary steps and measures to ensure the optimal use of water, considering seasonal, climatic, and demand fluctuations.
