after the war, new homes were built or completed by new residents and old. Residents established a grade school for white students about 1900 in an old two-story building opposite the Lutheran church. A few years later the school was relocated into a new two-story building between 4th and 5th streets. It had a steeple belltower and bell to signal recess and lunch periods, and the daily opening and closing of school. That building was used for at least 40 years for both grade school and high school. First known as the Effingham Institute. Its name was changed in the early 1920s to Rincon High School. Racial segregation continued to exclude African Americans from this school. By 1929 the corporate government of the small town had become inactive, in part due to the small population. Sometime later, however, the population began to increase. By 1950 the population was 454. By 1955 it was 650 and by 1960 it was 1,057. Rincon was reincorporated and organized as the Town of Rincon around the end of 1954. The incorporated limits of Rincon originally formed a circle having a diameter of , with the center at the site of the old (now gone) railroad depot, but annexations of land since the late 20th century have changed this shape. In approximately 1934, Georgia State Route 21 was paved from the Chatham County line in the south, northward through Rincon and Springfield and beyond. In about 1939, electric lines were installed, and electric power was supplied from the Savannah Electric and Power Company, replacing private individual small plants. These improvements were made during the Great Depression to provide jobs to working men, with assistance from the federal government under the WPA program of President Franklin D. Roosevelt, whose administration invested heavily in infrastructure in the South. In late 1955, Rincon installed its own city pump, tank, lines and water system, enabling "running water" throughout for the first time. In 1956, a volunteer fire department was organized. Also beginning in that year, many arterials and streets were paved. As suburban development has expanded outward from Savannah, since 1990 the population of Rincon has grown rapidly, rising from 2,697 in 1990 to an estimated 9,638 in 2014. Geography Rincon is located in southeastern Effingham County at (32.293258, -81.234171). Georgia State Route 21 passes through the town, leading northwest to Springfield, the county seat, and south to Savannah.
