The township is mostly served by the Hamilton post office, but the northeast corner is in the Oxford post office's territory. Nearly all of the township is in the Cincinnati Bell Telephone Company's Hamilton exchange, but the northwest and north central sections are in Verizon's Oxford exchange. Electricity is provided by the Cincinnati Gas and Electric Company, mainly along U.S. Route 27 and State Route 177. The remaining areas are served by the Butler County Rural Electric Co-operative .

Schools
Most of the township is in the Talawanda City School District, which was formed by the merger of the Oxford, Hanover, Milford, and Somerville school districts in 1953. However, parts of the township are in three other districts. The Ross Local includes a section on the southern border, the Hamilton City includes territory in the southeast adjacent to the city of Hamilton, and the Edgewood City has a small piece of the township's northeast corner.
