On December 7, 2022, Columbus City Utilities (CCU) was once again awarded the Plant of the Year honors by the Southern Indiana Operators Association (SIOA) at their annual meeting. The award was presented to CCU in recognition of the excellence displayed at its wastewater plant, located on South Jonesville Road in Columbus. Travis Calhoun, WWTP Superintendant, accepted the award on behalf of CCU.

CCU makes history with this award as the only facility to win the award two years in a row. In comments made at the event, SIOA officials stated that CCU’s Wastewater Treatment Plant sets the example for the standard that other wastewater treatment plants are striving to achieve, citing the leadership, management and staff as key components to its success.

Constructed in 2010, CCU’s Wastewater Treatment Plant began operations in May 2011. It averages a daily flow of 13.9 million gallons of water and can handle a peak of 39 million gallons of water for treatment per day.
