Bingöl Drinking Water Transmission Line Rehabilitation Project Construction

Noktasal Proje Mühendislik has successfully completed the “Bingöl Drinking Water Transmission Line Rehabilitation Project”, which is carried out in order to provide a healthy, sustainable and uninterrupted drinking water supply to the provincial center of Jul and its surroundings. The project aimed to re-evaluate existing water resources, comprehensively renovate the existing infrastructure system and increase the long-term operational security of the system with advanced engineering solutions.

The Purpose of the Project

The project aims to transfer approximately 600 liters/second flow rate of water obtained from Kürük 1, 2, 3 and 4 containers, which are the main drinking water sources of Bingöl provincial center, to the provincial center in a healthy way. In line with this goal, new transmission lines have been built, existing water intake structures and collection depot (TO-1) have been rehabilitated, aging lines that have completed their operational life have been canceled and a system with modern standards has been created.

Engineering Studies and Technical Analyses

Design and Construction of Transmission Lines

The transmission line route, which exceeds 11 kilometers in total, has been determined in accordance with flow rate, pressure class and topographic slope analyses and has been designed with HDPE (PE100) pipes of different diameters. The pipes used in the lines have a pressure class of 6, 10 and 12.5 atmospheres.

• The section of the line from the Kürük 1 container to the TO-1 collection room was built as about 755 meters with HDPE pipes with a diameter of 630 mm and resistant to 6 atm pressure.< / li>
• The short connection lines from Kürük 2 and Kürük 3 to TO-1 have been laid with pipes with a diameter of 630 mm and a total length of 340 meters.< / li>
• In the section from TO-1 to Suction cup-1, which is the first suction cup point of the system, a 441 meter long transmission line was constructed with pipes with a diameter of 1000 mm and a strength class of 10 atm.< / li>
• In the section of the main transmission line from the existing Suction Cup 1 to Suction Cup 5, a new line with a diameter of 900 mm and a length of 4,436 meters has been installed with PE100 pipes with a pressure class of 12.5 atm.< / li>
• In addition, starting from the Discharge point 1 of the system to the Some 41 zone, another 4,107 meter long line has been laid with pipes with a diameter of 710 mm and again suitable for a pressure of 12.5 atm.< / li>

Existing roads were used along the line routes, temporary service roads were opened in areas without transportation, and after the construction was completed, these roads were rehabilitated and made available for service.

Art Structures and Hydromechanical Equipment

A large number of art structures have been built on the lines for the safe and sustainable operation of transmission lines. Pressure balancing and air evacuation systems are of great importance, especially in regions where there are high elevation differences and long transmission distances.

• Suction cup structures have been included in the project as 9 units, 3 of which were built in the Dec Decking between Suction Cup 1 and Suction Cup 5, and 6 of which were built between Drain 1 and Some 41.< / li>
• The evacuation structures are planned as a total of 11 units, 4 of them are located in the Suction Cup 1-5 section, 7 of them are located in the Evacuation 1–Some 41 section.< / li>
• In addition, a project has been made to include 1 desk room on the system, and the unloading, maintenance and operation of the system have been facilitated.< / li>

Architectural, static and reinforced concrete projects for all art structures were prepared by Dotasal Proje Mühendislik and transferred to the application together with the necessary detail drawings and hydromechanical equipment projects.

Rehabilitation of Capstan and Collection Structures

Kürük 1, 2, 3 and 4 containers, which are the most important water resources in the region, and TO-1 collection room were examined in detail from a static, hydraulic and structural point of view, and the condition of the existing reinforced concrete building elements was reviewed.

In all structures;

• repair of concrete cracks by injection, plaster renovations, application of insulation systems suitable for contact with drinking water (for example, geomembrane or sliding insulation),
• Reinforcement exposures, water tightness problems and removal of deformations in the outer shell of the structure,
• Renovation of ventilation chimneys, steel fabrications (railing, door, stairs, etc.) maintenance and painting,
• Rearranging the drains around the building and opening the blocked sections,
• Many improvement steps have been carried out, such as the arrangement of environmental security elements (fence, entrance gate, transportation routes).< / li>

These improvement studies were carried out primarily in accordance with the “improvement projects” prepared as a result of field exploration and technical investigations and with the approval of the Administration. Decontamination and test certificates have been searched for in all materials to be used, and quality assurance has been provided.

Regulator Area Protection Operation

A protection wall about 400 meters long and 2 meters high has been designed and built for the captainage, which is at risk of staying within the lake area of the SAF 1 Regulator built by DSI near the Kürük 1 captainage. This structure has been dimensioned according to geotechnical and hydraulic principles in order to ensure the safety of the water intake system.

Implementation Projects and Technical Documentation

The following set of documentation has been prepared by Dotasal Proje Mühendislik, based on the application:

• General situation plans with a scale of 1/25,000,
• Account profiles with a scale of 1/1000 and 1/10000,
• Plan-profile sheets (1/100 - 1/500),
• Architectural, reinforced concrete and mechanical details of art structures,
• Evacuation lines and foot structures,
• Cross-section drawings, special pipe parts, cathodic protection calculations,
• Service roads and access projects.< / li>

These projects have been prepared by taking into account many engineering parameters such as height, slope, topographic and geological features, ground grade and bearing strength.

Measures Taken during the Construction and Operation Process

During the construction process of the project, the existing drinking water transmission lines were operated without interruption, and the transitions to the new transmission lines were made in a controlled manner. Field teams have made connection changes without interrupting the water supply of the surrounding settlements. Jul.

In addition, during the construction process, many stages such as pipe transportation, stocking, horizontal and vertical transitions, art structure positioning were carried out under quality assurance procedures. At the end of the project, all deteriorated roads, landscaping and temporary structures have been restored.

Result

The Bingöl Drinking Water Transmission Line Rehabilitation Project has been a critical step in terms of the water safety of the region; it has been completed in accordance with modern engineering principles and high quality standards. In this project, Dotasal Project Engineering has contributed to the service of the people of Bingöl with the protection of water resources, the establishment of efficient transmission systems and long-lasting infrastructure solutions.

This project has been recorded as one of the sample studies reflecting the engineering depth our company has in the design and implementation projects of drinking water systems and its solution-oriented approach in the field.
