The structure acts as an integral part of the city's coastal sanitation system, specifically designed to transport treated effluent away from the immediate shore.
It is a popular location for local anglers who utilize the extended reach of the pier to access deeper water.
The Submarine Outfall in Rio das Ostras serves as a functional maritime engineering project that doubles as a prominent coastal landmark in the Costazul neighborhood. It consists of a long, concrete walkway extending into the Atlantic Ocean, designed for water treatment discharge. The structure provides an elevated vantage point for observing the meeting of the coastal currents and local marine life. It is situated directly along the coastline, acting as a natural barrier that separates sections of the local beach. The area is highly regarded for its panoramic views of the Rio das Ostras shoreline and the horizon. Visitors frequently use the walkway for sea-watching and photography due to its projection into the ocean.
