A big celebration was held on January 14, 1914, to commemorate the arrival of electrical power, the addition of a water tank and supply system for indoor pumping and a new park for South Jordan. By the 1930s, the area needed a water tank to store water for residents living further west. The only way to get a federal grant was to incorporate and become a city. Citizens voted to incorporate on November 8, 1935, and immediately issued bonds to obtain money for the water tank. The city was initially governed by a Town Board with responsibilities over parks, water and the cemetery. In 1978, the city moved to a mayor-council form of government and assumed local supervision of police, fire, road and building inspections from Salt Lake County.
