March 4, 2026:
Village Board awarded contract for construction to DiMeo Brothers, Inc.
As part of the ongoing water main improvement project, Public Works staff will be working ahead of the contractor, to hydro excavate b-boxes and verify the current inventory of water service line materials. Once the service line material is identified the sidewalk will be marked with an “L” for lead or a “C” for copper.
If the service line is identified as lead the Village staff will contact the homeowner—either in person orby phone—to discuss replacement options. The Village will replace the entire lead service line from the water main to the water meter located inside the home. This will be performed by the Village's contractor at no expense to the homeowner. The homeowner will have the choice to opt out of the service line replacement. Should the homeowner opt out of the replacement a waiver must be signed.
The lead service line will be replaced with a copper water service line. The new copper service line will be directionally bored into the home. To do this, a small receiving pit will be dug inside the home near the water meter—typically in an unfinished area of the basement where the water line enters the foundation. After the new line is connected, the pit will be backfilled with stone and capped with concrete. There will be no need to dig up your front lawn- only the parkway area near the new b-box will be disturbed. A licensed plumber will be on site during the installation process.

What kind of work will be done?
In general, the process of installing the new water main will include: Saw cutting of road; Open cut trenching of the road; Installation of new water main; Pressure testing and chlorination of the new watermain; Reinstatement of water services; Pavement restoration.
Will services to my property be affected?
There will be no changes in regular services such as garbage pick-up, mail delivery, or emergency services from the Police and Fire Departments. There may be times during the day when construction activities temporarily block access to your driveway as the new water main is installed. We will try to make these interruptions as short as possible. If new curb or sidewalk is to be installed in front of your property, access to your driveway will be interrupted for a more extended period. In that case, you will receive more specific information about the schedule for this work and how it affects your driveway access within the next few weeks. During that time the Police Department will be instructed to relax the restrictions on overnight street parking at these locations while driveways are not accessible. If you have special needs due to a disability, please contact the Public Works Department. Please use caution when driving through the construction zone.
How will my water be affected?
