As the third instalment in our six-part water capabilities case study series, the Carene Drinking Water Supply Project highlights setec’s expertise in large-scale pipeline design and hydraulic optimisation. With growing demand, ageing infrastructure, and increasing sustainability pressures, UK water utilities face significant challenges. The Carene project in Loire-Atlantique, France, showcases innovative solutions that address these issues, providing valuable insights for the UK water sector.

Project Overview

• Client: Local authorities of Loire-Atlantique
• Location: Carene, France
• Timeline: September 2013 – March 2017
• Scope: Design and construction supervision of an 80km drinking water pipeline, including multiple pump stations and underground crossings.

Key Challenges & Solutions

1- Long-Distance Water Distribution

• – Challenge: Ensuring optimal pressure and flow efficiency across an 80km pipeline.
• – Solution: Advanced hydraulic modelling using Epanet reduced energy consumption and operational costs an approach UK utilities can adopt to enhance efficiency.

2- Navigating Complex Infrastructure

• – Challenge: Underground crossings of major roads, including the RN165 and RN171 motorways.
• – Solution: Tunnel boring and directional drilling minimised disruption critical for UK projects near motorways and urban areas.

3- Environmental Compliance & Sustainability

• – Challenge: Meeting stringent environmental regulations while maintaining project efficiency.
• – Solution: Sustainable construction strategies, including controlled construction schedules and eco-friendly materials, aligned with UK Environment Agency standards and AMP8 sustainability objectives, supporting Net Zero Carbon goals.

Project Outcomes

• – Enhanced Supply Resilience: Strengthened long-term water distribution for a large region, offering a scalable model for UK utilities.
• – Operational Efficiency: Hydraulic modelling optimised energy use, reducing long-term operational costs.
• – Minimal Environmental Impact: Compliance-driven sustainability measures ensured regulatory adherence and future-proofed the network.
