Borealis BorSafe™ pipe materials help Kuzeyboru strengthen wastewater infrastructure in northern Türkiye

The new pipeline is 1600 mm in diameter and stretches 4.5 kilometers, making it the largest polyethylene (PE) pipe system of its kind in the region. Kuzeyboru, a leading Turkish pipe manufacturer, used a PE100 Black grade with excellent sag resistance from our BorSafe™ portfolio to produce the large-diameter pipes.

Founded in 2001, Kuzeyboru specializes in infrastructure and superstructure pipe systems. With modern production facilities and experience delivering solutions to over 100 countries across five continents, the company is well-equipped to take on infrastructure projects of this scale and complexity.

“This project reflects our commitment to delivering reliable, high-performance solutions that support the infrastructure needs of growing cities,” says Bülent Karaman, Kuzeyboru CEO “Working with trusted partners like Borealis helps us ensure the quality and longevity of the systems we build.”

PE100 Black ready-made compound materials are a type of high-density polyethylene designed for use in pressure pipe systems. With a Minimum Required Strength of 10 MPa, they offer the durability and performance needed for demanding infrastructure applications.

The grade used in this project is part of our BorSafe family of PE pressure grades. BorSafe materials are known for their durability, resistance to abrasion and chemicals, and suitability for modern installation techniques. These qualities support the construction of cost-effective, long-lasting infrastructure systems that are fit for the future.

BorSafe materials also contribute to sustainability in several ways. They are easy to process, helping reduce emissions during production. Their strength and durability contribute to longer lifespans, minimizing the need for repairs or replacements—in fact, the resilience of well-designed polyethylene pipe systems during earthquakes and ground movements is well documented in official failure statistics. The result is greater material efficiency and a lower environmental impact over the full system lifecycle.

This project highlights the value of close collaboration across the value chain. By working with customers like Kuzeyboru, we help enable solutions that bring lasting benefits to communities. Once complete, Samsun’s upgraded system will help reduce odor and environmental pollution, improve public health, and support the city’s continued growth.

“This is a great example of how the right materials, used by the right partners, can help cities build infrastructure that lasts,” explains John Webster, Borealis Head of Marketing Infrastructure. “Our BorSafe™ grades are designed to meet the real-world demands of modern infrastructure—and in the hands of Kuzeyboru, they’re supporting long-lasting systems that the community of Samsun can rely on for decades to come. It’s exactly what we mean when we say our solutions are made for generations.”
