Water Treatment Plant

The Evansville Water and Sewer Utility operates a conventional surface water treatment plant that has the capacity to draw up to 60 million gallons of raw water a day from the Ohio River. The plant filters, treats, monitors and delivers on average 23 million gallons of safe, quality drinking water daily through more than 1,000 miles of water lines to approximately 200,000 people in Southwest Indiana.

Proposed New Water Treatment Plant

Like many cities across the country, Evansville Water and Sewer Utility’s (EWSU’s) water treatment plant is nearing the end of its useful life. Over the past 125 years, the facility has undergone multiple expansions and improvements to keep the plant in operation. In continuing to meet our commitment of providing a reliable supply of safe drinking water that meets or exceeds all federal and state water quality standards, EWSU is embarking on a plan to construct a new 50 million-gallon water treatment facility that will serve Evansville and surrounding communities.

The plan includes a $177 million water plant to be constructed adjacent to the existing plant, plus $43 million to replace water mains associated with the relocation of existing roads and buildings. The current plant will remain in operation while the new facility is built. The new water treatment plant is expected to go online in 2027.
