Lead Service Lines in Eau Claire, WI

Overview

Eau Claire has a population of about 78,000 served by 76 different water systems. The largest is Eau Claire Waterworks, which serves roughly 70,600 people. The remaining systems serve smaller populations—commercial buildings, institutions, and community centers.

Currently, there are no known lead service lines reported in Eau Claire's water systems inventory data. This is good news, but it doesn't mean lead isn't present—it means either systems haven't found any, or they haven't completed a full survey yet.

What you need to know

Lead service lines are pipes that connect your home to the public water main. If yours exists, water travels through lead for part of its journey to your tap. Lead is a serious health concern, especially for children and pregnant people—even small amounts in drinking water can cause problems.

Wisconsin requires water utilities to maintain an inventory of known and suspected lead service lines. Eau Claire Waterworks and other local systems are responsible for identifying which homes have them and reporting that information to the state.

Your home might have a lead service line even if it's not on a "known" list yet. Utilities are still in the process of surveying pipes, especially older ones. Homes built before 1986 are at higher risk—that's when federal rules tightened on lead in plumbing.

How to find out about your home

Contact Eau Claire Waterworks directly—they maintain records on your specific address. Ask whether your service line has been identified, tested, or remains unknown. If it's unknown, you can request a survey or arrange a test.

You can also hire a licensed plumber to inspect the line from your meter to your home (the part you own and pay for).

If lead is found

Your utility is required to provide information on reducing exposure. Common steps include:

  • Flushing your tap for 30 seconds before drinking or cooking
  • Using a lead filter certified by NSF International
  • Replacing the line (often split between homeowner and utility)

For health concerns, contact your doctor or the CDC.

Next steps for residents

  • Contact Eau Claire Waterworks (phone or website) to ask about your service line status
  • If unsure, request a visual inspection or water test from your utility
  • If you have young children, talk to your pediatrician about lead exposure
  • Keep records of any testing or replacement work done

Common questions

How do I know if my Eau Claire home has a lead service line?

Contact Eau Claire Waterworks with your address—they maintain an inventory and can tell you the status of your service line. If it's listed as unknown, ask for a survey or inspection. Homes built before 1986 are at higher risk.

Is lead in Eau Claire water dangerous?

Lead in drinking water poses serious health risks, especially for children and pregnant people. Even low levels can affect development and learning. If you're concerned, talk to your doctor and consider testing your water.

What should I do if my Eau Claire home has a lead service line?

Start with short-term steps like flushing your tap and using a certified lead filter. For a permanent fix, contact your utility about replacement programs—Wisconsin and federal grants may cover part of the cost.

Are water filters effective against lead?

NSF-certified filters can reduce lead in drinking water, but they require regular replacement. Filters treat water at the tap only, not throughout your home—a service line replacement is the only permanent solution.
