2024 – For the needs of the Alagyaz Municipality: Construction of a drinking water pipeline in Alagyaz settlement; rehabilitation of the drinking water pipelines in the Mirak and Rya-Taza administrative areas. Development of design and cost estimate documentation as part of consulting services. 

During the design phase, an assessment was carried out on the technical condition of the Alagyaz community’s water supply system and hydraulic structures, including the main pipeline (OKJ). The study included evaluation of actual and calculated flows and operating regimes to address the issue of drinking water scarcity in the upper areas of the community, caused by insufficient capacity in the recently built but underperforming system.

The design proposed and applied measures such as constructing an additional pipeline for the neighborhood and integrating it with the existing network to form a unified system, which will help increase water supply for the entire community, especially the targeted neighborhood. Technical and economic analyses, as well as hydraulic calculations, were conducted. Based on the potential for maximizing the use of gravitational energy, the most economically efficient pipeline route, diameters, and connection point—linked to the daily regulation reservoir—were selected.

For the other project components in the Mirak and Rya-Taza administrative areas, the existing but corroded metal pipelines were assessed, hydraulically modeled, and replaced with HDPE pipes. New, optimal routes and diameters were selected for these pipelines. The implementation of these works will contribute to extending water supply hours, increasing system reliability, reducing infiltration losses, and improving available water volumes.

Technical Description and Indicators of the Proposed and Completed Works

• Valve nodes, air valves, pressure regulators, and system drainage manholes: 13 units
• Construction of water supply network in the project areas: 6.6 km
