FORT WAYNE, Ind. (WOWO): An insurance company has sued the city of Fort Wayne after nearly 31 Fort Wayne homes were damaged by sewer-water.

According to the Journal Gazette, the lawsuit was filed last week on behalf of the residents, whose homes were damaged in 2013 by overflowing sanitary sewers.

Indiana Farm Bureau Insurance says another incident happened on August 22nd, where more properties were invaded with sanitary and/or storm sewer water, as reported by the Journal Gazette.

Court documents stated the city's 1200 miles of sewers should have been able to handle the water without invading local homes.

Fort Wayne has been abiding by rules that were put in place by the U.S. Environmental Protection Agency and the Indiana Department of Environmental Management, after the city violated the Clean Water Act in 2008.

Since then, the city has been separating sanitary and storm sewers as a legal obligation. That project should be completed in the next 18 years and will cost an estimated $240 million, according to the Journal Gazette.
