SIOUX CITY WATER SUPPLY Lead Service Line Inventory
Sioux City Water Supply serves approximately 85,791 people in Iowa. Like all water utilities in the US, it is required to inventory lead service lines (LSLs)—the pipes that connect the public water main to individual homes and buildings.
What you need to know
Lead service lines can leach lead into drinking water, especially in homes with corrosive water or where pipes are older and deteriorating. Infants, young children, and pregnant people face the greatest health risks from lead exposure.
The inventory status for Sioux City Water Supply shows that data on known lead lines, galvanized pipes, and non-lead pipes has not yet been publicly reported or is still being compiled. This does not mean your home is safe or unsafe—it means the utility is still in the process of documenting which lines exist and what they are made of.
What the law requires
The EPA's Lead and Copper Rule requires all water systems to:
- Identify and inventory all service lines
- Replace lead lines on a schedule
- Provide the public with inventory data
Utilities have different timelines depending on their size and when they began this work. Sioux City Water Supply has not yet reported which service lines are lead, galvanized, or made of other materials.
What you can do now
Contact your utility directly. Call or email Sioux City Water Supply and ask:
- Whether your property address is on a lead service line
- If they have partial inventory data not yet posted online
- When a full inventory will be available
- What free testing or treatment options they offer
Test your water. Some utilities offer free lead testing kits. Even if your service line is not lead, lead can enter water from older fixtures or solder inside your home.
Get advice on treatment. If your water shows elevated lead, ask your utility about certified filters or other steps you can take. The CDC has guidance on reducing lead exposure at home.
Next steps for residents
- Contact Sioux City Water Supply directly to ask about your service line status and available testing programs
- Request a free lead test if your utility offers one, or find a certified lab
- Review CDC guidance on lead in drinking water and reducing household exposure
- Check back periodically as the utility completes its inventory and posts updated information

Frequently asked
How do I know if I have a lead service line?
Contact your water utility with your address; they should have or be developing inventory records. You can also hire a licensed plumber to inspect the pipe where it enters your home, though this requires excavation. Testing your water is another step to detect lead exposure.
Is lead service line water safe to drink?
Lead can leach into water from lead service lines, especially if water is corrosive or pipes are old. The only safe level of lead for infants and children is zero. If you're concerned, test your water and contact your utility about treatment or replacement options.
When will Sioux City replace lead service lines?
Contact Sioux City Water Supply directly for their replacement schedule and timeline. Federal funding is available to help systems replace lead lines, and your utility should have a plan in place.
What should I do if my tap water has lead?
Use bottled water for drinking and cooking until you address the issue. Contact your pediatrician or the CDC if you're concerned about health effects. Ask your utility about certified filters, replacement programs, or other treatment options.
