Staecnon-RJ is a trade union representing workers in the sanitation sector (water and sewage), based in the city of Campos dos Goytacazes, in the interior of the state of Rio de Janeiro.
Its foundation began in 1932 as a movement to organize the working class in the sanitation sector through the formation of a Cooperative. Later, in 1961, the workers met in an Extraordinary General Assembly and founded the Professional Association of Workers in the Water Purification and Sewage Services Industry of Campos and region.
The following year, in 1964, the workers obtained approval from the Ministry of Labor to transform the Association into a Union. The full acronym for Staecnon-RJ is Union of Workers in the Water Purification and Distribution Industries and in Sewage Services of Campos and the Northern and Northwestern Region of the State of Rio de Janeiro.
The current headquarters of the Union is located at Rua Marechal Floriano, 147, Centro. The union's territorial area of operation comprises 25 municipalities, with cities being served by the state-owned public company or by private companies.
