WATERLOO WATER WORKS Lead Service Line Inventory
About This Water System
Waterloo Water Works serves 69,504 people in Iowa. The utility draws water from groundwater sources.
Lead Service Line Inventory Status
As of now, Waterloo Water Works has not yet completed or published a lead service line inventory. This means the utility has not yet systematically identified which homes are connected to the water system via lead service lines—the pipes that run from the main water line under the street to individual homes.
This is not unusual. The Safe Drinking Water Act requires all US water systems to complete lead service line inventories, but many systems across the country are still in early stages of this work. Completion timelines vary by utility and state.
What This Means for Residents
Without a published inventory, you cannot look up your address to learn whether your home has a lead service line. However, you can still take steps to protect your household:
- Contact Waterloo Water Works directly. Call or email the utility and ask whether your specific address has a lead service line. They may have partial records even if a full inventory isn't public yet.
- Check your home's age and construction records. Homes built before 1980 are more likely to have lead service lines, though they can exist in newer homes too.
- Get your water tested. A certified lab can test your tap water for lead. This is often the fastest way to know if lead is reaching your home, regardless of pipe material. Your utility or local health department can recommend testing labs.
- Use a certified lead-reducing filter on your kitchen tap if you're concerned. NSF/ANSI Standard 53 certified filters remove lead from drinking water.
Health effects of lead exposure, especially for children, are serious. If you have questions about testing or remediation, contact your pediatrician or the CDC.

Frequently asked
Does Waterloo Water Works have lead in the water?
Waterloo Water Works has not yet published whether it has identified lead service lines in its system. Lead in drinking water typically comes from service lines and plumbing, not the water treatment process. Contact the utility directly to ask about your address, or have your water tested by a certified lab.
How do I know if my house has a lead service line?
You can contact Waterloo Water Works and ask about your address. If your home was built before 1980, it's more likely to have one. A plumber can also inspect the service line where it enters your home.
How do I get my water tested for lead?
Contact Waterloo Water Works or your local health department for a list of certified labs in the Waterloo area. Testing is usually inexpensive and takes a few days for results.
Is it safe to drink tap water from Waterloo?
Waterloo Water Works treats water to meet federal safety standards. However, if lead service lines exist in your neighborhood, lead can enter your water between the treatment plant and your tap. Testing your specific tap water is the best way to know.
