Submarine Outlet (Drainage Pipe) at Bristol, Municipal District of La Oliva

Project Description

The object of the Project “Submarine Outlet (Drainage Pipe) for the Discharge of Saltwater proceeding from the Desalination of Sea Water in Bristol” consists of defining the work necessary to return the water rejected by the Bristol Desalination Plant in the municipal district of La Oliva, as well as evaluating the effects that this has on the marine and coastal environment.
A drainage pipeline was chosen for the discharge of sea water proceeding from the desalination plant, and to this end this pipeline was designed, buried along all its length, covered by cement based rockfill in the maritime section to guarantee that the action of the waves does not uncover the pipeline.
The pipeline comprises a PVC tube measuring a total of 143.37 metres, with an external diameter of 250 mm and a nominal pressure of 4 atm.
- Land Section Length: 70 metres
- Maritime Section Length: 78.37 metres, including the diffuser section.
The Diffuser Section comprises a PVC tube running 4 metres, with an external diameter of 160 mm and a nominal pressure of 4 atm. It has 2 diffusers, spaced 2 metres apart.
The final point of discharge of the drainage pipe is located at the bathymetric level of -2.75 metres, measured against the maximum equinox low tide).
For the dimensioning of the drainage pipe, a working flow of 87 l/s in the year horizon was considered.
The occupation surface area of the maritime-coastal public domain to be acted on for the outlet was set at a total of 148.37 m2.
