Main sewer pipeline at River Sarela. Improvements to the sanitation system of Santiago de Compostela (A Coruña)

The main purpose of this project is to improve the sanitation system of the basin of River Sarela, in Santiago de Compostela. A sanitation network was designed in order to collect effluents by means of a secondary sewer pipeline connected to storm-water tanks. Subsequently, a sewer pipe network will bring the water to a control manhole that flows to the sanitation network of River Sar.

More than 3,350 m of pipeline were designed and built, including:

  • GRP pipes (Ø: 800 mm): 886.64 m
  • GRP pipes (Ø: 1,000 mm): 298.13 m
  • GRP pipes (Ø: 1,200 mm): 331.57 m
  • GRP pipes (Ø: 1,400 mm): 90.14 m
  • GRP pipes (Ø: 1,600 mm): 69.73 m
  • RC pipes (Ø: 1,800 mm): 1,658.25 m

GRP: Glass reinforced polyester RC: Reinforced concrete
