Background: Work kicked off in February 2021 and will continue to progress through 2023. Work includes over six miles of sanitary sewer main installed in the Turner Tract, Shields Valley and Piasa Valley areas of Alton.

When Illinois American Water acquired the Alton Regional Wastewater system the company made a commitment to address requirements set forth by the Illinois Environmental Protection Agency to remedy combined sewer overflows

The projects in Turner Tract and Shields Valley addresses 1.69 miles of sanitary sewer main.

The work in Piasa Valley began in the spring of 2021.

This project includes almost five miles of sanitary sewer main.

Work is expected to continue for over two years.

This does not mean work will occur in one area for 24 months, but rather, projects will continue to progress throughout neighborhoods during that time period. Signs will be placed ahead of construction to notify customers of upcoming closures.
