Lead Service Lines in Des Peres, MO

What we know about lead pipes in your area

Des Peres has a population of 173,427 served by 303 water systems. Based on available inventory data, no confirmed lead service lines have been reported in the systems serving this area. However, this doesn't mean lead pipes don't exist—it means either they haven't been inventoried yet, or inventories are still in progress.

The largest water systems serving Des Peres residents include Magnolia-Eden Isles (10,155 people), Magnolia-Greenleaves (8,031 people), and Magnolia-Resolve Whisperwood (6,867 people). These systems, along with dozens of smaller ones, are responsible for tracking lead service lines under federal regulations.

Why this matters

Lead service lines are the pipes that connect your home to the water main under the street. When water sits in a lead pipe overnight or for several hours, lead can leach into your tap water. This is especially concerning for infants and young children, whose developing brains are more vulnerable to lead's effects.

Even if your water system reports zero confirmed lead lines, you may still have one. Many systems across the country are still completing their inventories. A pipe that hasn't been found yet is still a pipe in the ground.

What you can do now

Contact your water utility directly to ask:

  • Whether your address has a lead service line
  • If they've completed their inventory for your neighborhood
  • What testing or replacement programs are available

Your utility should provide this information for free. If your water system hasn't inventoried your street yet, ask when they plan to.

Testing your water

If you're concerned about lead, you can request a free or low-cost water test from your utility, or purchase an inexpensive test kit. The CDC recommends testing if you have a lead service line, live in an older home (pre-1986), or notice discoloration in your water.

For health concerns, consult your pediatrician or the CDC's lead page.

Next steps for residents

  • Call your water utility and ask if your home has a lead service line
  • Request a water test if your utility hasn't confirmed your pipes are lead-free
  • Ask about replacement programs — many utilities offer cost-sharing or free lead line replacement
  • Note your water system's name (listed above) and have your address ready when you call

Common questions

How do I know if my home has a lead service line in Des Peres?

Contact your water utility directly—they have maps and records of service lines. You can also check your home's age (homes built before 1986 are higher risk) and look at the pipe connection under your sink or in your basement. If it's dull gray and soft enough to scratch with a coin, it may be lead.

Is the water in Des Peres safe to drink?

Des Peres water systems are required to monitor and report lead levels. No confirmed lead service lines have been reported, but that doesn't guarantee your home is lead-free. The best way to know is to contact your utility and test your water if needed.

What should I do if my home has a lead service line?

Contact your water utility about replacement programs—many offer partial or full funding. In the meantime, you can reduce risk by flushing your tap in the morning, using cold water for cooking and drinking, and installing a certified filter designed to remove lead.

Can I get my lead pipe replaced for free?

Many utilities across the country now offer free or subsidized lead line replacement. Contact your local water system to ask about their program—funding and eligibility vary by utility.
