Batavia Township is located in Kane County, Illinois. Unlike the prototypical Midwestern township, which is a six mile by six mile square, Batavia splits such a 6-mile (9.7 km) square with Geneva Township. Batavia Township comprises 18.37 square miles (47.6 km2) of land and 0.28 square miles (0.73 km2) of water. It is divided by the Fox River. Its population in the 2000 Census was 30,137. It has 10,797 housing units. The western part of the United States Department of Energy's Fermilab is located at the eastern edge of the township (formerly in the village of Weston), although most of the facility is located in neighboring Winfield Township in DuPage County.
