Locust/Colton CSO Elimination and Water Main Replacement Project
The City of Bloomington is requesting a $4,504,294 grant through the Rebuild Illinois Public Infrastructure Grant, with a local match of $170,000, for Phase Two of this project. The total Phase Two cost estimate is $4,674,294. The City held a public hearing during the June 24, 2020, City Council meeting to allow residents to view the construction plans and to learn about the project and its impacts on their property. No public comments were provided during this meeting. Council passed the item by a vote of 8-0. Click here to view the video of the vote.

The multi-phase Locust/Colton CSO project involves construction of new sanitary sewers, conversion of the existing combined sewer into a storm sewer, and laying new water main. The sewer portion of the project, with nine phases, is projected to cost nearly $14 million and last through most of the decade. Click here to view maps of all planned phases of this project. Phase One was completed in 2013. As part of the overall project, the City is implementing the philosophy of improving the overall infrastructure, including pavements, sidewalks and curb and gutters so that additional work will not be needed in the area for multiple decades. This comprehensive approach connects well with the revitalization efforts discussed in the Governor's Five-Year Economic Plan.
combined sewer overflow (CSO) can occur when storm water run-off combines with the
sanitary flow, usually during a heavy rain event, and discharges to an open body of water
such as a creek or stream (left image above). This project continues the work of installing new sewer
lines to separate the sanitary flow from the storm flow so that all sanitary flow is
treated at the Bloomington Normal Water Reclamation District (BNWRD) Waste Water
Treatment Plant (WWTP) prior to being discharged to Sugar Creek (right image above). In addition, older
water main will be replaced within the project limits while the area is under
construction. Click here to learn more about Combined Sewers and click here to learn more about Combined Sewer Overflow.
The project proposed for the Rebuild Illinois grant is Phase Two of the city’s Locust/Colton Combined Sewer Overflow Elimination Project, which began in December 2011. The project includes installation of 1,750 feet of new separate sanitary sewer and 20 to 30 new service laterals connecting resident’s homes to the new sanitary sewer line. It also includes replacing 450 feet of aged water main in the areas disturbed by sewer construction. Moore Street and Warner Street will receive new curb and gutter along with a new hot mix asphalt street overlay. Washington Street, Mercer Avenue and Grove Street will be resurfaced curb to curb in the areas impacted by the construction. Phase Two construction plans and bid documents are complete, and the project is ready to move forward but the project has not yet been bid. Subject to award of grant funds from Rebuild Illinois, the City would begin construction in March 2021. Click here for an overview map of the Phase 2 project limits.
Phase Two completion will:
Provide revitalization in a key downstate community in Illinois that supports multiple, large employers, including State Farm, Country Companies, and Illinois Wesleyan University
Help retain and attract businesses and addresses the challenge of outmigration with infrastructure modernization in downstate Illinois
Eliminate outdated combined sewers by separating sanitary and storm water flow
Remove the potential for sewer backups resulting from storm water into residents’ homes in the area
Phase Three Phase 3 of the “Locust/Colton CSO Elimination and Water Main Replacement
Project” continues the multi-phase project to eliminate the CSO at Locust and Colton
Street. Phase 3 began in March of 2020 with survey and design work.
