Salina Cruz, RCW supplies a desalination plant

|
directly at the beach of the pacific ocean ...
|
three RCW's were constructed to collect seawater. Therefore the caissons were sunk directly on the beach. The laterals were installed like a fan towards the ocean. Instead of construction of an open intake the advantage of this design was to collect salt water precleaned by the aquifer.
