History
Club Deportes Rengo was founded on March 18, 1984, under the auspices of the Rengo Football Association (ASOFUR) and belonging to the federated records of the Asociación Nacional de Fútbol Amateur (ANFA) in order to unify the local clubs in a single representative of the commune in the National Tournament of the Third Division of ANFA. For this reason, it adopted the name of Deportes Rengo, as well as the colors of the Association and Selection of the commune.
In the 80s, the club had the support of local collaborators, mainly industries established in the commune, such as Viamaxi, Temsa and the international Bticino, which had its factory in the city. In that decade, Deportes Rengo was an active participant in the division and for several years was a candidate for different promotions.
The club was a breeding ground for great players in the area, being the basis of the communal teams that won the national amateur championships three times in 1986 in Valdivia, 1989 in Curicó, and 1996 in the proper city of Rengo.
After those years, and with the gradual closure of the factories that mainly supported the institution, the club was left without the necessary economic support, which condemned it to relegation to the local federation of origin in 1997. Thus, it continued for several years, competing in local federation tournaments, and regional champions cup, with youth and adult series.
