The tender project for the outfall pipeline is being carried out. In all alternatives, it is proposed to replace the two pipelines of the base solution with a single larger-diameter pipeline, with better hydraulic performance and the corresponding savings in cost and time.
The common characteristics of all alternatives are:
• Material: RC tunnel and the rest in PE100.
• Jacking length: 1,021 m
• Total pipe length (RC+PE): 2,200 m (option 0), 2,500 m (option 1), and 3,000 m (option 2).
• Flow rate: 11 m³/s
The characteristics of each alternative are:
• Alternative 1: ID=1,966 mm. High pressure
• Alternative 2: ID=2,200 mm
• Alternative 3: ID=2,200 mm. High pressure
High-pressure solutions are addressed through the specific design of a plate compatible with the jacked tunnel.
Furthermore, a comprehensive marine climate study is being conducted.
