Lead Service Lines in Little Rock, AR

Little Rock's water systems serve about 380,000 people across 9 utilities. The good news: none of the major water systems in the area have reported confirmed lead service lines in their inventories. However, lead pipes can still exist in older homes, and incomplete records mean some lines may not yet be identified.

What we know about Little Rock's water systems

Central Arkansas Water is the largest utility, serving 368,455 people in the metro area. The remaining eight systems serve smaller populations, ranging from under 2,000 to just under 6,000 residents. As of now, none of these utilities have disclosed known lead service line counts in public records—which typically means either no lines have been identified, or inventories are still being completed.

Lead service lines are pipes that connect your home to the municipal water main. They were widely installed before the 1980s and pose a health risk, especially to young children and pregnant people. Even utilities with zero reported lead lines may still have unidentified ones, particularly in neighborhoods built before 1950.

Why the records might be incomplete

Federal law (the Lead and Copper Rule Revisions) requires all water systems to create and publish lead service line inventories by October 2024. Many utilities are still finishing this work. If your home was built before 1980, or you're unsure, it's worth asking your water provider directly whether they've assessed your property.

What galvanized pipes mean

Galvanized steel pipes (zinc-coated) were used as an alternative to lead but can corrode over time and leach lead into water. Little Rock's utilities haven't reported galvanized pipe counts either—another reason to check with your specific provider.

How to find out if your home has a lead service line

The most direct way: contact your water utility and ask about your service line. Central Arkansas Water (the system serving most of Little Rock) can look up your address. Older homes are at higher risk, but only your utility's records or a plumber's inspection can confirm.

Next steps for residents

  • Contact your utility — Call Central Arkansas Water or your local provider and ask if your service line is lead, galvanized, or copper. Provide your address.
  • Request a free or low-cost inspection — Many utilities offer this service or can recommend a licensed plumber.
  • Check your home's age — If built before 1950, assume higher risk until verified.
  • Review the utility's inventory — Ask for a copy of the lead service line inventory when it's published (by October 2024 federally).
