Lead service lines in Plymouth, MN

Plymouth serves about 79,564 people through 51 water systems. The good news: there are no known lead service lines reported in Plymouth's inventory data.

That said, "not reported" doesn't always mean "none exist." Many older homes—especially those built before 1986—may still have lead service lines that haven't been formally inventoried yet. Minnesota requires water utilities to identify and replace lead service lines, but the process takes time.

What you need to know

Lead service lines carry water from the street main into your home. If yours is made of lead, corrosive water can leach lead into your drinking water. The risk is highest in homes built before the 1986 ban on lead pipes.

Plymouth's main utility (serving 76,546 people) has not yet reported its lead service line inventory to the state. The smaller systems—including parks and schools—are also still in the process of surveying their lines. This doesn't mean lead lines are present; it means data collection is ongoing.

Your water utility should know your line material. Contact the City of Plymouth Water Department or your specific water system to ask:

  • Is your home's service line made of lead, copper, or galvanized steel?
  • When was it installed?
  • Has it been tested for lead?

If you rent, contact your landlord or property manager with the same questions.

Steps to reduce lead exposure

Even without a lead service line, lead can come from older fixtures (faucets, solder). If you're concerned:

  • Use cold water for drinking and cooking. Hot water dissolves lead more readily.
  • Let water run for 30 seconds before drinking if the line has been idle for several hours.
  • Test your water. Minnesota health departments offer free or low-cost testing.
  • Check for lead paint in homes built before 1978—it's often a bigger source of exposure than water.

Next steps for residents

  • Contact the City of Plymouth Water Department to ask about your service line material.
  • Request a free water test through Hennepin County Public Health or your local health department.
  • If you have children under 6 or are pregnant, talk to your pediatrician or OB-GYN about lead screening.
  • Learn more about Minnesota's lead service line replacement program at the Minnesota Pollution Control Agency (MPCA) website.

Common questions

Does Plymouth Minnesota have lead in the water?

Plymouth's water systems have not reported any known lead service lines in their inventories. However, many utilities are still surveying their systems, so data is incomplete. Contact your water utility to ask about your specific home's service line.

How do I know if my house has a lead service line?

Call the City of Plymouth Water Department with your address. They can tell you the material of your service line. You can also hire a plumber to inspect it, or look at your home's original plumbing documents if you have them.

What should I do if my water tests positive for lead?

First, use cold water for drinking and cooking, and flush the line by running water for 30 seconds before use. Contact your water utility and local health department. If children or pregnant people live in your home, consult a pediatrician or OB-GYN.

Can I get my lead service line replaced in Plymouth?

Yes—Minnesota offers funding and assistance for lead service line replacement. Contact the Minnesota Pollution Control Agency (MPCA) or the City of Plymouth Water Department to learn about programs and costs.
