Joliet begins $594M water main replacement program targeting pre-1970 pipelines

The City of Joliet is set to embark on a significant water main replacement program in 2025, with plans to replace nearly 30 miles of aging infrastructure. During the March 4 council meeting, Allison Swisher, the director of public utilities, outlined the ambitious initiative, which targets water mains constructed before 1970. The total cost of the program is estimated at $75 million, with funding primarily sourced from low-interest loans through state and federal programs.

The primary goal of the replacement program is to reduce non-revenue water, which is water that is produced but not billed to customers, often due to leaks. Swisher emphasized that addressing these leaks is crucial for meeting the city's target of maintaining non-revenue water at or below 10% by 2030. The program also includes the replacement of lead service lines, with the city aiming to eliminate all lead lines by the same deadline, at no cost to residents.

To ensure effective communication with the community, the city has developed a comprehensive outreach plan. This includes an interactive website featuring project maps, contractor details, and regular updates. Additionally, over 3,500 letters were sent to residents in affected areas, and an open house is scheduled for residents to engage directly with project representatives.

Swisher highlighted the importance of coordination with other city projects to minimize disruptions, stating, "We want to have a policy of only digging once." This approach aims to streamline construction efforts and reduce the burden on residents during the process.

As construction season approaches, city officials are urging residents to stay informed and exercise patience as the program unfolds. The 2025 water main replacement initiative represents a proactive step towards enhancing Joliet's water infrastructure and ensuring a reliable supply for its residents.
