WENTZVILLE PWS Lead Service Line Inventory
What you need to know
Wentzville PWS serves about 41,784 people in Missouri. Like many water systems across the US, the utility is required by federal law to identify and report on lead service lines—the pipes that connect the water main to individual homes.
Current status: Wentzville PWS has not yet completed a full lead service line inventory. This means the utility is still in the process of locating and documenting which homes may have lead service lines.
Why this matters
Lead service lines are a known source of lead in drinking water. If your home was built before 1986, there's a higher chance your service line contains lead. Even newer homes can have lead lines, though it's less common.
Lead in drinking water can affect health, particularly for children under 6 and pregnant people. The CDC provides resources on reducing lead exposure at home.
What Wentzville PWS should do next
Federal law requires every water system to:
- Map all service lines in their system
- Identify which ones contain lead, are galvanized steel (which can leach lead), or are unknown
- Develop a plan to replace lead service lines
- Share this information with customers
Until Wentzville PWS completes its inventory, you won't have official confirmation about your specific address—but you can take steps now.
What you can do today
- Contact Wentzville PWS to ask about your service line material. Even without a complete inventory, the utility may have records for your address.
- Test your water for lead. Many labs offer affordable testing (typically $20–50). The EPA's database can help you find certified labs in Missouri.
- Use a filter. If you're concerned about lead, a NSF/ANSI 53-certified filter on your tap or a pitcher filter can reduce it while you wait for official information.
- Flush your tap. If water has sat in pipes overnight, run cold water for 30 seconds before drinking or cooking.
Next steps for residents

Frequently asked
Does Wentzville PWS have lead in the water?
Wentzville PWS is still mapping which homes have lead service lines. Until the inventory is complete, the utility cannot confirm lead levels for specific addresses. You can request your home's service line information directly from the utility or test your water at a certified lab.
How do I know if my house has a lead service line?
Call Wentzville PWS and ask about your address. You can also hire a plumber to inspect the line where it enters your home, or have your water tested. The EPA's website has a guide on identifying lead pipes visually.
Is it safe to drink tap water while waiting for the inventory?
For added peace of mind, you can use a NSF/ANSI 53-certified filter, flush your tap for 30 seconds after it sits unused, and avoid using hot tap water for drinking or cooking. If you have young children or are pregnant, ask your doctor or pediatrician about your specific situation.
When will Wentzville PWS finish its lead service line inventory?
The utility has not yet announced a completion date. Contact them directly to ask about their timeline and replacement plan. You can also request updates from your local water department or city council.
