    Pioneering 3D Printed Structures Revolutionize the Water Industry

    A groundbreaking collaboration between Tarmac, Yorkshire Water, and Hyperion Robotics is revolutionizing the water industry with the introduction of 3D printed concrete structures. The partnership, which also involves Mott MacDonald Bentley (MMB), aims to bring sustainable construction solutions to the forefront.

    The project has seen the creation of four custom-designed drawpits using 3D printed concrete. Drawpits are essential for housing electrical cabling and ensuring high-quality water filtration at sewage treatment works. Traditional drawpits are heavy and require significant amounts of materials, contributing to a high carbon footprint.

    However, the newly developed 3D printed drawpits have reduced embodied carbon by an impressive 40% compared to conventional drawpits. The structural engineering of these drawpits meets Eurocode standards, ensuring their reliability and durability.

    This innovative construction technique relies on advanced robotic technology to create precisely designed structures. By utilizing 3D printing and low-carbon cement technology, the project demonstrates the potential for sustainable solutions in the construction industry.

    The benefits of 3D printed concrete structures extend beyond carbon savings. The use of dry-silo mortar factory production methods and efficient construction techniques also lead to cost savings. This model not only aligns with the industry’s goal of achieving a net-zero built environment but also enhances operational efficiency.

    The successful implementation of 3D printed drawpits at Yorkshire Water’s sewage treatment works sets the stage for further exploration of this technology in the wider construction industry. Through continued collaboration with Hyperion Robotics, Tarmac aims to apply the key learnings and advancements to other construction projects.
