The topsoil layer, also known as the humus layer, plays a critical role in agricultural and environmental health. Managing this layer involves the collection and storage of topsoil from a designated area, adhering to specific regulations. This process is vital and regulated by law, as the topsoil layer is rich in organic matter, microorganisms, and nutrients, which are essential for plant growth and development. This layer provides necessary nutrients and water to plants, making its preservation crucial. It is noteworthy that the formation of just 1 cm of fertile topsoil can take anywhere from 100 to 1,000 years, depending on various factors.
The implementation of any kind of infrastructural (and not only) project often necessitates the removal of the topsoil layer. However, international standards and local legislation, specifically the "Technical Regulation on the Removal, Storage, Use, and Reclamation of Fertile Soil Layer," approved by the Government of Georgia's Resolution No. 424 of December 31, 2013, strictly outline the procedures for its removal and storage.
During the preparatory construction phase, Bakhvi HPP has responsibly managed the topsoil layer removed from the surface by placing it in specially designated areas. The soil is stored in cavalier piles, not exceeding a height of 2.5 meters, with an inclination angle not exceeding 45 degrees. Furthermore, to prevent degradation of the quality of the stored fertile layer due to rain and wind, the soil is compacted slightly.
Upon the completion of construction work, the stored topsoil layer will primarily be used to restore temporary areas utilized during the project to their original state. This approach underscores our commitment to environmental protection and sustainable development, ensuring the preservation of vital natural resources for future generations.
