Plymouth Water System Lead Service Line Inventory
Plymouth, Minnesota serves a population of 76,546 people. Like all US water systems, Plymouth is required by federal law to maintain an inventory of lead service lines — the pipes that connect the water main under the street to individual homes.
What we know about Plymouth's inventory
As of now, Plymouth has not yet completed a public lead service line inventory. This does not mean there are no lead pipes in the system; it means the utility is still in the process of identifying them. Federal deadlines for completing these inventories vary based on system size and other factors.
The inventory process typically takes several years. Utilities use a combination of methods: reviewing old records, field sampling, and inspections. Once complete, Plymouth will make this information available to residents.
What lead service lines are
A lead service line is the pipe that carries water from the street into your home. Many homes built before 1986 have these pipes, though age alone doesn't guarantee it. The only way to know for sure is through testing or a utility inventory record.
Lead enters your water when it dissolves from the inside surface of these pipes. Water sitting in pipes overnight or during the day can contain higher levels. The risk is highest in homes with lead service lines and corrosive water (water that lacks minerals that protect pipes).
What you can do now
Testing: Contact Plymouth to request a free or low-cost water test. Results will show whether lead is present in your water right now.
Reducing exposure while you wait: If concerned, you can use a filter certified for lead removal (look for NSF certification), or boil and cool water. Run cold water for 30 seconds before using it for drinking or cooking to flush out water that's been sitting in pipes.
Health concerns: If you have young children or are pregnant, talk to your pediatrician or doctor about exposure risk. The CDC has guidance on lead and health.

Frequently asked
How do I know if I have a lead service line in Plymouth Minnesota?
Plymouth is still completing its service line inventory. Contact the utility directly and ask them to check their records for your address. You can also request a free water test to see if lead is present in your tap water right now.
Is Plymouth water safe to drink?
Plymouth regularly tests water quality and meets federal safety standards. However, if your home has a lead service line, lead can leach into your water. A free water test from the utility will tell you if lead is present in your home's water.
What should I do if my house has a lead service line?
The safest long-term solution is replacement, which usually requires professional work. Ask Plymouth about replacement assistance programs. In the meantime, use a certified lead-removing filter or run cold water for 30 seconds before use.
When will Plymouth finish its lead pipe inventory?
Plymouth's timeline is not yet public. Contact the water utility to ask when they expect to complete the inventory and when results will be available to residents.
