Arup has played a pivotal role in assisting the STRABAG-Equitix consortium in being selected as the preferred bidder for the Haweswater Aqueduct Resilience Programme (HARP) by United Utilities. The programme is a major infrastructure project aimed at replacing sections of the 110 km-long Haweswater Aqueduct, which supplies clean water to Greater Manchester and the North West. This ambitious project highlights Arup’s multidisciplinary expertise in tackling complex infrastructure challenges.
As the strategic design partner, Arup collaborated closely with STRABAG UK’s Design & Build Contractor team during the tender process. Their responsibilities included delivering designs for permanent works such as tunnels, shafts, site access, and civil and mechanical and electrical (M&E) components of the clean water infrastructure. This partnership has produced a robust technical solution addressing critical project risks for both the contractor and the asset owner.
M&E Design and Integration: A Key Success Factor
In a project like HARP, where water infrastructure is central, M&E design and integration are essential. Arup’s building services engineering expertise ensured the effective incorporation of mechanical, electrical, and public health systems into the project. This comprehensive approach supports operational efficiency and longevity, with the replacement tunnel sections designed for a 120-year service life.
Arup’s commitment to resilient, high-quality design underscores the importance of sustainable infrastructure. With services spanning building physics, control systems, and digital integration, Arup is a leader in innovative engineering solutions, as evidenced by its contribution to HARP.
STRABAG and Equitix: Leaders in Infrastructure Delivery
STRABAG, a European construction heavyweight, specialises in tunneling, civil engineering, and infrastructure projects. Known for its precision and innovation, STRABAG brings decades of experience in delivering large-scale engineering projects. Equitix, a leading investor in infrastructure assets, contributes its financial and operational expertise to ensure project success. Together, the STRABAG-Equitix consortium is well-positioned to deliver HARP, leveraging their complementary strengths.
A Shared Commitment to Resilience
United Utilities’ HARP project represents a critical investment in the North West’s water resilience. The partnership between Arup, STRABAG, and Equitix showcases a unified effort to address challenges in maintaining and renewing essential infrastructure. Arup’s strategic design services will continue to support the project through tunneling, civil, and water engineering expertise during the delivery phase.
This collaboration highlights the vital role of engineering innovation in creating infrastructure that meets today’s demands while securing resources for future generations.
