Lead Service Lines in Columbia, South Carolina
Columbia City of Water serves about 319,500 people. Like all water systems across the US, it is required by law to identify and inventory lead service lines—the pipes that connect homes to the public water main.
What we know about Columbia's lead service lines
The utility has not yet reported detailed inventory data to the state. This means we don't have a confirmed count of how many lead service lines exist in the Columbia water system, or how many have been replaced or are confirmed to be lead-free.
This is not unusual. Many water systems are still in the early stages of completing their lead service line inventories, which is a multi-year effort. The Safe Drinking Water Act requires utilities to finish their inventories and make that information available to the public.
How to find out if your home has a lead service line
Contact Columbia City of Water directly. They can tell you whether your specific address has a lead service line, galvanized pipe, or copper. You can also ask:
- Whether they have a publicly available inventory or map
- When they expect to complete their full inventory
- What replacement programs or financial assistance they offer
- Whether they recommend water testing or flushing
Request a copy of your service line records. Utilities often have historical files, permit records, or construction documents that identify pipe material.
Hire a plumber to inspect your property. If you want certainty before your utility completes its inventory, a licensed plumber can access and identify your service line material—usually for $100–300.
What to do if you have a lead service line
Lead in water comes primarily from old pipes and solder, not from the water source itself. If your service line is lead, you can reduce exposure by:
- Running cold water for 30 seconds before drinking or cooking (especially first thing in the morning)
- Using only cold water for cooking and infant formula
- Considering a certified lead-reducing water filter while replacement is pending
Replacement is the only permanent fix. Ask your utility about replacement programs, rebates, or low-interest loans.

Frequently asked
Does Columbia have lead in the water?
Lead comes from pipes and plumbing, not from the water source. Columbia City of Water has not yet reported a complete lead service line inventory, so we don't know how many lead pipes are in the system. Contact the utility directly for your address.
How do I know if my house has a lead service line?
Call Columbia City of Water and ask about your service line. You can also hire a licensed plumber to inspect it, or request historical records from the utility. Many systems don't have complete records yet.
Is it safe to drink tap water in Columbia?
Columbia treats its water to meet safety standards. However, if you have a lead service line at home, lead can leach into your water. Run cold water for 30 seconds before drinking or cooking, and consider a certified lead-reducing filter while awaiting replacement.
How much does it cost to replace a lead service line?
Replacement costs vary by location and depth but typically range from $1,500 to $3,000+. Ask Columbia City of Water about rebates, grants, or low-interest loan programs they may offer to residents.
