The city of Rochelle agreed to make $830,000 in sewer repairs and upgrades to settle a federal lawsuit filed by residents.
They claimed their homes and property were flooded with raw sewage because of leaks in the city's sewer lines.
Rochelle plans to install new sewer pipes, manholes and a new pumping station by the end of November.
Jeffery Monroe, attorney for the city of Rochelle, says they felt the lawsuit, filed last summer, was unnecessary because improvements to the city's sewer lines were already in the works.
But Alisa Coe, an attorney with EarthJustice who represented the citizens, says when they filed the lawsuit last summer, there were no specific plans on paper.
EarthJustice is a non-profit environmental law firm that agreed to take the case after the citizens contacted them and asked for help.
