Submarine Outfalls

Submarine Outfalls

Outfalls are some of the most unique elements of sanitation in coastal areas, since its design combine environmental, hydraulic and constructive.

IH Cantabria's experience in this field is very wide and is supported by its participation in the design of over 30 emissaries worldwide. The work done by the IH range from the design of large urban sewage outfalls (Santander, Gijon, Oviedo, Bilbao, Baku, Montevideo, ...) to the study of industrial effluents and brines through subsea pipelines.

The Institute has its own models for the study of key issues such as initial dilution, dispersion and transport of substances or design of subsea protection.
