The new Integrated Overflow Control Plan is mandated by the Indiana Department of Environmental Management and the U.S. Environmental Protection Agency. The utility says it will improve and modernize Evansville's sewer system. The current system needs to be replaced because of possible water contamination.
"The combined sewer system handled the sanitary side and the storm water side," said Director of Evansville Water and Sewer Utility Allen Mounts, "if it rains, it will overflow. It goes into the river, so it doesn't back up into the streets."
In the long run, customers will see rate increase. But how much has not been determined.
