Construction of Submarine Outfalls
Submarine outfalls: Solutions for wastewater transport
En Eurohinca contamos con amplia experiencia en la construcción de submarine emissaries, infraestructuras esenciales para el transporte seguro de aguas residuales tratadas hasta el mar. Nuestros sistemas cumplen con normativas ambientales estrictas y garantizan la protección de los ecosistemas marinos.
The Asociación Internacional del Agua (IWA) señala a los emisarios como una herramienta clave en la gestión sostenible del agua, integrando eficiencia y respeto ambiental.
Subsea outfalls with polyethylene pipelines
Para estos proyectos utilizamos tuberías de polietileno de alta densidad (PEAD), que aportan resistencia, durabilidad y facilidad de instalación en condiciones marinas adversas. Estas conducciones se aplican también en proyectos de captaciones de agua de mar y desagües de presas, donde se requiere fiabilidad a largo plazo.

Frequently asked questions about submarine outfalls
En la sección de frequent questions respondemos a las dudas más habituales sobre diseño, instalación y mantenimiento de emisarios, así como las ventajas frente a otros sistemas de conducción.
What is a submarine outfall and what is its main function?
A submarine outfall is a pipe or system of pipes that is installed underwater to transport wastewater from a treatment plant to the sea or other body of water. Its main function is to evacuate wastewater safely and efficiently, minimizing environmental impact and ensuring adequate treatment prior to release into the aquatic environment.
Why are polyethylene pipes used in the construction of submarine outfalls?
Polyethylene pipes are chosen for the construction of subsea outfalls due to their high corrosion resistance, durability and flexibility. Polyethylene is resistant to the effects of salt water and adverse marine conditions, ensuring long service life and reliable performance in closed sewage conveyance.
How is a submarine outfall installed and what are the main steps in the process?
The installation of a submarine outfall generally follows these steps:
- Study and planningSubmarine terrain evaluation and outfall design.
- ManufacturingProduction of pipes and necessary components.
- TrenchadoExcavate a channel in the seabed for pipe laying.
- InstallationLay the pipes in the channel and join them according to the design.
- Testing and reviewSystem check to ensure that there are no leaks and that the system is working properly.
- Closing and coverageFilling the channel and securing the pipes in place.
What are the environmental benefits of using submarine outfalls for wastewater disposal?
Submarine outfalls help reduce the environmental impact of wastewater by:
- Dilute and disperseThe wastewater is mixed and diluted in seawater, reducing the concentration of pollutants.
- Minimize contaminationBy releasing wastewater into the open sea, the accumulation of pollutants near the coast is prevented.
- Improving treatment: They ensure that treated wastewater is released in areas where its impact is less.
What maintenance do submarine outfalls require and how often?
Subsea outfalls require periodic maintenance to ensure optimal performance. This includes:
- Regular inspectionsVerification of the state of the pipes and connections.
- Cleaning: Elimination of sediments and other accumulated residues.
- Pressure testingTo ensure that there are no leaks. Maintenance is typically performed every 1-2 years, although it may vary depending on environmental conditions and use of the outfall.
What measures are taken to ensure the structural integrity of submarine outfalls during their lifetime?
