MADISON SUBURBAN U.D. Lead Service Line Inventory
What You Need to Know
MADISON SUBURBAN U.D. serves approximately 81,203 people in Tennessee. Like all water utilities in the US, they are required to identify and track lead service lines—the pipes that connect the public water main to individual homes.
Current status: The utility has not yet completed a comprehensive lead service line inventory. This means the exact number of lead service lines in the system is unknown at this time.
Why This Matters
Lead service lines are a real source of lead in drinking water, particularly in homes built before 1980. Even low levels of lead exposure can affect children's learning and development. If you live in an older home served by MADISON SUBURBAN U.D., your home may have a lead service line—but you won't know unless the utility completes its inventory and tests.
What's Happening Now
Federal law requires all water systems to complete lead service line inventories and develop replacement plans. MADISON SUBURBAN U.D. is working toward this requirement. Until the inventory is complete, the utility cannot tell you whether your specific property has a lead service line based on official records.
What You Can Do Right Now
Get your water tested. Testing is the fastest way to know if lead is present in your water. MADISON SUBURBAN U.D. may offer free or low-cost testing—contact them directly to ask about testing programs or qualified labs in your area.
Check your home's age and pipe materials. If your home was built before 1980, the risk is higher. You can sometimes see service line material in your basement where the water enters the house (copper, lead, or galvanized steel look different). Copper is safe; lead is soft and dull gray; galvanized steel is silver with a bumpy texture.
Keep an eye on utility updates. MADISON SUBURBAN U.D. will publish its lead service line inventory as it becomes available. Check their website or contact them for timelines.

Frequently asked
Does MADISON SUBURBAN U.D. have lead in the water?
The utility has not completed a full lead service line inventory yet, so the exact scope is unknown. To know if *your* water has lead, contact the utility about free or low-cost testing. Testing is the only way to get a definitive answer for your home.
How do I know if my house has a lead service line?
Once the utility's inventory is complete, they will notify customers. In the meantime, you can check your basement where water enters the house—lead is soft, dull gray, and can be scratched with a coin. Copper and galvanized steel are silver-colored. If unsure, ask a plumber or contact the utility.
Is it safe to drink tap water from MADISON SUBURBAN U.D.?
The safest approach is to have your water tested. If testing shows lead above EPA's action level, use a pitcher filter certified for lead (NSF 53) and contact your utility about service line replacement. For health concerns, speak with your doctor.

The utility is still completing its inventory, which is the first step before a replacement plan can be finalized. Contact them directly for their timeline and any available replacement programs.
