Lead Service Lines in Oklahoma City Water System
What you need to know
Oklahoma City Water Utilities serves 644,000 people. Lead service lines—the pipes that connect the water main to your home—can leach lead into drinking water, especially in older homes and when water is corrosive.
The status: As of now, Oklahoma City has not yet inventoried its lead service lines. This means the utility doesn't have a public count of how many lead lines exist in the system. Federal law requires all utilities to complete this inventory and share findings with residents.
Why this matters
Lead exposure has no safe level. Infants, young children, and pregnant women face the highest health risks. Even small amounts can affect learning and development. Lead also affects adults—it can raise blood pressure and damage kidneys over time.
If your home was built before 1986, your service line is more likely to contain lead. Homes built in the 1970s–1980s may have galvanized steel pipes, which can also release lead under certain conditions.
What Oklahoma City should do next
The utility needs to:
- Create a written plan to identify all lead and galvanized service lines
- Test water or inspect pipes in representative neighborhoods
- Share results publicly, including a map or list by address when possible
- Develop a timeline and funding strategy for replacing identified lead lines
Until inventory data is available, residents can't know their risk level. This is a gap that the utility should address urgently.
What you can do now
Contact Oklahoma City Water Utilities directly to ask:
- Whether your service line has been tested for lead
- What your water's corrosion control measures are
- When the lead inventory will be completed and published
If you're concerned about lead in your home's water, a water test is inexpensive ($10–25) and widely available through county extension offices.
Next steps for residents
- Contact your water utility — ask about your service line material and request an inventory timeline
- Check your home's age — if built before 1986, assume elevated risk until proven otherwise
- Consider a water test — especially if you have young children or are pregnant
- Learn about filters — NSF-certified filters can reduce lead if a line replacement isn't immediate

Frequently asked
Does Oklahoma City have lead in the water?
Oklahoma City hasn't yet completed a public inventory of lead service lines, so there's no official count. However, lead lines are common in older cities, and pipes built before 1986 are at higher risk. Contact the utility to ask about your home's line.
How do I know if my house has a lead service line?
Homes built before 1986 are more likely to have lead lines. Oklahoma City Water Utilities can tell you if your address has been tested. You can also ask a plumber to inspect the pipe where it enters your home—lead is soft, dull gray, and leaves a mark if scratched.
Is Oklahoma City water safe to drink?
Oklahoma City treats its water and monitors for contaminants. However, lead can enter water through old pipes on the way to your home. If you're pregnant, have young children, or are concerned, a water test or NSF-certified filter is a reasonable precaution.
When will Oklahoma City replace lead service lines?
The utility has not yet published a replacement timeline. Federal law requires utilities to complete lead inventories and develop replacement plans. Contact Oklahoma City Water Utilities to ask when results will be public and what funding is available for line replacement.
