LOUISVILLE WATER COMPANY Lead Service Line Inventory
Louisville Water Company serves approximately 764,769 people in Kentucky. This page explains what we know about lead service lines in their water system and how to find out if you have one.
What we know right now
Louisville Water Company has not yet reported detailed information about lead service lines to the public directory. This means we don't have confirmed counts of how many lead, galvanized, or unknown service lines exist in the system.
Lead service lines are pipes that connect the water main in the street to your home. If your home was built or connected before the 1980s, there's a higher chance your service line contains lead. Even homes built in the 1990s and 2000s can have lead pipes.
Why this matters
Lead can leach into drinking water, especially in homes with acidic water or if pipes are disturbed. The CDC recommends that families with young children, pregnant people, or nursing mothers take this seriously. Even low levels of lead exposure in children can affect learning and development.
What you should do
Contact Louisville Water Company directly to ask:
- Does my address have a lead service line?
- Do you have a lead service line replacement program?
- What's the timeline for replacing lead lines?
Ask for your service line material in writing. Some utilities have already inventoried their lines; others are working on it now under the federal Lead and Copper Rule updates.
If you rent
Landlords are responsible for disclosing lead service lines in rental properties. Ask your landlord or property manager about your building's service line. You can also contact Louisville Water Company with your address.

Frequently asked
How do I know if I have a lead service line?
Contact Louisville Water Company with your address and ask directly—they should have records or can send someone to inspect your line. You can also look where the water line enters your home; lead is soft, gray, and can be scratched with a coin.
Is it dangerous to have a lead service line?
Lead can leach into drinking water, especially if your water is acidic or the line is damaged. The risk is highest for young children, pregnant people, and nursing mothers. The CDC recommends testing your water if you suspect a lead service line.
Can Louisville Water Company replace my lead service line?
Many utilities now offer lead line replacement programs, sometimes at no cost to residents. Contact Louisville Water Company to ask if they have a program and what your options are.
What should I do while I wait to replace a lead service line?
Use a certified lead-reducing filter (NSF/ANSI 53), flush cold water for 30 seconds before drinking, and avoid hot tap water for drinking or cooking. Have your water tested to check for lead.
