Lead Services Inventory and Replacement Act

In August 2021, Governor Pritzker signed into law the Lead Services Inventory and Replacement Act mandating the replacement of all lead service lines in the state. Having a lead water service should be a concern but not a panic.  

The Lead Service Line Notification Act now requires public water suppliers in Illinois, including the Village of Winthrop Harbor, to replace all lead service lines within the community from the watermain to the water meter in the home. A portion of the service line is on the residents' property and owned by residents. 

The Village is in the process of developing a lead service line replacement plan for the community. This effort will require resident cooperation so the Village can compile a complete inventory of all homes with confirmed lead service lines. This is why completing the lead service line questionnaire is so important. 

Village of Winthrop Harbor Lead Services Line Replacement Plan


The State of Illinois requires the replacement of all lead service lines per the Lead Service Line Replacement and Notification Act (415ILCS5/17.12). Per the Illinois statute, the Village must create a multi-year approach to replace all the privately-owned lead service lines in the Village. 


As a first step, the Village has created an inventory of suspected lead service lines in Winthrop Harbor. The Village will mail homeowners letters with information on how to perform a self-survey or schedule inspections to verify the status of suspected lead service lines.

Steps to Identify a Lead Water Service Pipe 

Follow the steps on this page to perform a self-identification of your service line. Use the photographs to help determine your 

water service line material. 

Step #1

Locate the water service line entering the building. This is typically found in the basement. A valve and the water meter are installed on the pipe after the point of entry. 

Identify a test area on the pipe between the point where it enters the building and the valve. If the pipe is covered or wrapped, expose a small area of metal.

Step #2

Scratch the surface of the pipe. Use the flat edge of a screwdriver to scratch through any corrosion that may have built up on the outside of the pipe.

Step #3

Compare your pipe to the chart below. Each type of pipe will produce a different type of scratch, react differently to the magnet, and produce a unique sound when tapped with a metal coin.  DO NOT use a knife or other sharp instrument.

Lead Pipe

Lead pipe will be a dull silver, or blue-gray in color. Lead pipe will be shiny when scratched. Lead pipe is not magnetic, so a magnet will not stick to it.

Copper Pipe

Copper pipe may be shiny, like a new penny, or orange/brown in color. When scratched it will shine like a new penny. Copper pipe is not magnetic, so a magnet will not stick to it

Galvanized Pipe

Galvanized steel pipe may be shiny or dull, silver or gray in color, and shiny like a new nickel when scratched. A  magnet will stick to it.

Step #4
