Stones removed during the construction of the largest water reservoir in Latin America were used in the Submarine Outfall Divulgação/Sabesp and Alexsander Ferraz/AT The largest treated water reservoir in the form of a tunnel in Latin America was excavated inside two hills in Baixada Santista, on the coast of São Paulo. According to g1, the stones removed during construction were used to form the Santos Submarine Outfall. With capacity to store 110 million liters, the tunnel was excavated in granite gneiss rocks that are around 600 million years old, the same formation as Sugarloaf Mountain, in Rio de Janeiro (RJ). The structure goes from Morro Santa Terezinha, in Santos, to Morro Voturuá, in São Vicente. ?Click here to follow the g1 Santos channel on WhatsApp. To the reporting team, Sabesp explained that the stones removed during the works on the Santa Tereza-Voturuá Reservoir-Tunnel were used to cushion the impact of waves and form the platform that protects the submarine outfall pipe.

The equipment consists of a pipe used to discharge sanitary or industrial sewage into the high seas, taking advantage of the high self-purification capacity of marine waters. The Santos Submarine Outfall has been located in the José Menino neighborhood since the 1970s. The equipment is responsible for the final disposal of household waste treated by the Saturnino de Brito Sewage Pre-Conditioning Station (EPC). Before that, evictions were launched in Canto do Forte, in Praia Grande. According to Sabesp, the outfall was designed due to the need to expand the system, driven by population growth and tourist interest, in addition to the lack of treatment prior to launch into the high seas. Construction of the Santos Submarine Outfall Reproduction/Constran and Disclosure/Sabesp ?How does it work? The outfall does not have an exhaust at the end of the pipe. Also according to Sabesp, the tip is closed and the effluents are released through diffusers — a sequence of openings located in the final meters, like a flute, for example. The equipment has four kilometers of pipes, 1.75 meters in diameter, which came by boat from Italy. The company highlighted that the technological alternative is internationally recognized and can also be found in sewage systems in countries such as the United States, New Zealand, China, Spain and Portugal. ?How was the emissary’s sports and leisure area built? Sabesp said that several suggestions for using the stretch of beachfront where the pipeline starts were raised in the 1980s. Among them, a bus parking lot for guests at the city's hotels. Santos City Hall added that the construction works for the outfall were carried out by Sabesp. Subsequently, the company transferred the old construction site to the municipality, which gave rise to the Roberto Mário Santini Municipal Park, in 2010. Parque Municipal Roberto Mário Santini, in Santos, SP Alexsander Ferraz/AT The project was designed by architect Ruy Ohtake and features an iron sculpture by his mother, artist Tomie Ohtake, in honor of 100 years of Japanese immigration. The area brings together leisure options, such as a skate park, bike path, outdoor exercise equipment and space for skating. The place also hosts cultural events, presentations and sporting meetings by the sea, in addition to housing the Santos Surfing Museum, dedicated to the history of the sport in the city and in Brazil. The collection brings together more than 70 historic boards, including equipment used by big names in the sport, such as Gabriel Medina, Ítalo Ferreira, Adriano de Souza, Kelly Slater and John John Florence. Discover the Santa Tereza/Voturuá Reservoir-Tunnel reservoir located on the border between São Vicente and Santos Divulgação/Sabesp To g1, Sabesp informed that the Santa Tereza-Voturuá Reservoir-Tunnel serves Santos and São Vicente, in addition to reinforcing the supply of Guarujá and Praia Grande. Also according to the company, the structure is strategic for water security in Baixada Santista. Construction began in 1979 and ended in 1981, being carried out simultaneously on the side of both cities. As previously disclosed by Sabesp, the tunnel was built 42 meters above the sea so that the supply would be by gravity, saving resources with electrical energy. The reservoir is more than a kilometer long and is divided into two chambers, each about 13 meters high and 15 meters wide. See how much capacity is equivalent to: ?220 million 500 ml water bottles; ?44 Olympic swimming pools with 2.5 million liters of water; ?55 thousand tanker trucks with a capacity of 2 thousand liters.
