Closed Tubular Irrigation Networks in the Republic of Uzbekistan

The problem:

Agriculture in Uzbekistan is highly dependent on efficient irrigation systems, particularly in regions with challenging topographies such as foothills and areas with steep slopes. Traditional open canal systems, while historically prevalent, are increasingly becoming insufficient due to water loss, maintenance difficulties, and inefficiencies in water distribution. In areas with significant slopes, the risk of erosion and water wastage is heightened, leading to suboptimal agricultural productivity and increased operational costs.

Moreover, the existing irrigation infrastructure often struggles with water pressure management, particularly when crossing railways, highways, and other obstacles, further complicating the delivery of water to agricultural lands. In colder regions, the use of inappropriate materials in irrigation networks can lead to damage from freezing temperatures, reducing the lifespan of the infrastructure. The challenge lies in designing a modern, closed tubular irrigation network that can efficiently manage water resources, minimize losses, and withstand varying environmental conditions. This is crucial for ensuring the sustainability and productivity of Uzbekistan's agricultural sector, which is a cornerstone of the national economy.

The solution:

InfoCapital Group LLC (ICG) conducted a Pre-Feasibility Study and Design Review for the implementation of closed tubular irrigation networks in Uzbekistan. The study began with an exhaustive review of regulatory documents and design norms, including the specific guidelines for irrigation systems as outlined in the ""General Scheme for the Use of Irrigated Lands, Water Resources, and Their Protection in the Republic of Uzbekistan for the Period until 2005"" and the ""Soil Cover Atlas of the Republic of Uzbekistan.""

ICG conducted a detailed feasibility study to identify regions where closed tubular networks could be effectively implemented, taking into account local materials and existing infrastructure. Extensive data collection was carried out on the length and condition of on-farm irrigation networks across various regions. This was followed by rigorous hydraulic calculations to determine the optimal pipe diameters required to handle water flows ranging from 0.1 to 1.0 m³/sec, depending on the terrain's slope and other environmental factors.

The industry overview conducted by ICG identified local enterprises capable of producing the necessary polyethylene pipes and fittings, ensuring that the materials used would be suitable for the specific needs of the project. Finally, ICG provided a comprehensive design proposal for the closed tubular irrigation networks, incorporating advanced features such as hydraulic shock protection devices and ensuring that the pipes were laid at appropriate depths to prevent freezing in colder zones. This solution not only addresses the inefficiencies of traditional open canal systems but also sets the stage for a more sustainable and productive agricultural sector in Uzbekistan.
