Lead service lines in Janesville, WI

If you're buying a home or concerned about your drinking water in Janesville, you may have heard about lead service lines. Here's what you need to know about the situation in your area.

What we know about Janesville's water system

Janesville is served by 43 public water systems. The largest is the Janesville Water Utility, which provides water to about 64,415 people. Other systems serve smaller populations at workplaces, schools, and facilities like Heritage Hall.

The good news: no lead service lines have been identified in Janesville's reported inventory data. However, this doesn't mean they don't exist—it means either they haven't been found yet, or systems haven't completed their surveys.

Why lead service lines matter

A lead service line is the pipe that connects your home to the city water main underground. If your home was built before the 1980s, there's a chance your service line contains lead. When water sits in these old pipes, especially if it's corrosive, lead can leach into your drinking water. This is a real health concern, particularly for young children and pregnant people.

What Janesville Water Utility is doing

Wisconsin water utilities are required by federal law to identify lead service lines and report findings. The Janesville Water Utility serves the vast majority of residents and is responsible for knowing which pipes contain lead. If they haven't reported known lead lines yet, it may mean surveys are still underway or the system uses corrosion control to reduce risk.

How to find out about your home

The most direct way is to contact your water utility. If you're served by the Janesville Water Utility, call or email them with your address—they can tell you whether your service line is lead, galvanized, copper, or unknown. If you're in a smaller service area (like a workplace or facility), ask for the name of your water system first.

You can also hire a plumber to inspect your line, or do a simple visual test if you can access it in your basement or yard.

Next steps for residents

• Contact Janesville Water Utility with your address to ask about your service line material
• If you rent, ask your landlord or property manager
• Get your water tested if you want added certainty about lead levels (your utility can recommend a lab)
• Use cold water for drinking and cooking—hot water leaches more lead from pipes
