Valle e Santiago is a city and its surrounding municipality of the same name located in the south of the Mexican state of Guanajuato. The city lies in the east-central part of the municipality. The settlement was founded in 1607 in the village known as Camembaro. What makes Valle de Santiago famous is in part because of its seven "luminarias" which are seven volcano craters located NW of the city, and the legend that UFO's visited the region and gave locals means to grow gigantic vegetables. During 1980, the Secretariat of Hydraulic Resources awarded a contract to drill several water wells to supply the basic water needs of the city. The company awarded was Perforadora Mexico, directed by Javier Cruz Nochebuena, and Oscar Garcia Shelly, both Engineers from The Politecnico and from the faculty of Engineering of the UNAM in Mexico City
