Lead Service Lines in Summerville, SC
Summerville's water systems serve about 157,700 people through 22 different utilities. Right now, none of them report known lead service lines in their inventories—but that doesn't mean there are zero lead pipes in the ground. It means the data isn't complete yet.
Why the uncertainty?
Water utilities across the country are still in the process of mapping their service lines. Federal rules require utilities to identify and replace lead service lines, but many communities are still conducting surveys. A utility showing "no known lead" often means they haven't finished their inventory yet, not that their pipes are definitely lead-free.
Your water system
Summerville is served by multiple utilities depending on your address. The largest is Summerville CPW, which serves about 81,750 people. Other significant systems include DCWA Knightsville (40,141 people) and DCWS Ashley Phosphate (26,536 people).
Your utility is responsible for:
- Locating and inventorying all service lines (the pipe running from the main to your house)
- Replacing lead lines on public property
- Informing you if your line is lead or unknown
The utility does not replace the portion of the line on your private property—that's your responsibility.
What you can do now
Find out which utility serves you. Contact Summerville CPW or check your water bill; it will name your provider. Ask them directly: "Do you have a record of my service line material?" They may have old records, even if their formal inventory isn't finished.
Get a simple water test. If you have young children, are pregnant, or just want peace of mind, test your water. Your utility can either provide a kit or recommend a certified lab. A test costs $15–50 and tells you if lead is present right now in your tap water. This is different from knowing whether your pipes are lead—it's a real-time health check.
Reduce exposure while you wait. If you don't know your line's material, the safest approach is to run water before using it for drinking or cooking. Let cold water run for 30 seconds to 2 minutes each morning or after the water has sat for several hours. This flushes out stagnant water that may have absorbed lead from pipes.
Health concerns
Lead affects children's brain development even at low levels. If you have children under 6 or are pregnant, contact your pediatrician or the CDC. They can advise you on testing and next steps based on your situation.
Next steps for residents

- Get a free or low-cost water test through your utility or local health department.
