Streamwood and Hoffman Estates have agreed to work together to repair a sanitary sewer pipe along Route 59 that serves both villages.
The total cost of the project -- which includes the construction of more than 1,000 feet of sewer and four manholes -- is almost $282,000. Streamwood will be responsible for nearly $157,000 in work, while Hoffman Estates will be responsible for about $125,000.
Streamwood and Hoffman Estates also will equally split the cost of engineering, which combined totals about $20,000.
Both villages approved an intergovernmental agreement for the repair of the sewer last month, but Hoffman Estates approved a final, revised agreement Monday that included minor changes by Streamwood's village attorney.
Sections of the sewer are severely corroded and need to be lined as soon as possible, officials said. Streamwood's portion of the project includes more than 330 feet of 36-inch pipe and two manholes, while Hoffman Estates' portion includes about 710 feet of 18-inch pipe and two manholes.
The project is expected to begin this month and be completed in December.
