CITY OF ROCKVILLE Lead Service Line Inventory
The City of Rockville water system serves approximately 52,000 people in Maryland. Like all US water utilities, Rockville is required to inventory lead service lines—the pipes that connect homes to the public water main—and share that information with residents.
What is a lead service line?
A lead service line is a pipe made of lead that carries drinking water from the public water main into your home. Lead is a toxic metal that can leach into water, especially in homes with older plumbing. Even small amounts of lead exposure can affect children's development and learning. If you live in an older home (built before the 1980s), there's a higher chance your service line contains lead.
What Rockville's inventory shows
As of now, the City of Rockville has not yet completed or publicly shared a lead service line inventory. This doesn't mean there's no lead in the system—it means the utility is still in the process of identifying which homes have lead service lines and which do not.
Under the Biden-Harris administration's Bipartisan Infrastructure Law, water systems across the country received federal funding to accelerate lead service line replacement. The EPA has also set stricter rules requiring utilities to complete and share their inventories with residents.
How to find out about your home
Your best next steps are to:
- Contact the City of Rockville directly and ask whether your specific address has a known lead service line.
- Request information about when the inventory will be available to the public.
- Ask about replacement programs—many utilities now offer free or subsidized replacement if you have a lead service line.
If you're concerned about lead in your drinking water right now, you can also request a water test through the utility or use a certified lab.
Next steps for residents
- Contact the City of Rockville water department to ask about your home's service line status.
- Request updates on when the lead service line inventory will be publicly available.
- Consider having your water tested if you have a young child or are pregnant.
- Learn more about lead health effects and water safety from the EPA's lead in drinking water page.

Frequently asked
How do I know if my home has a lead service line in Rockville?
Contact the City of Rockville water department directly—they can check your address in their records. You can also hire a plumber to inspect the pipe where it enters your home, though this may cost $100–300.
Is lead in Rockville's water dangerous?
Lead is toxic, especially for children and pregnant people. Even low levels can harm development and learning. If you're concerned about health effects, talk to your doctor or pediatrician, or contact the CDC.
Can I remove lead from my tap water myself?
Certain water filters (NSF/ANSI certified for lead reduction) can reduce lead in your tap water. However, the best long-term solution is replacing a lead service line. Talk to your water utility about replacement programs.
Does the City of Rockville have money to replace lead service lines?
Utilities nationwide have received federal Bipartisan Infrastructure Law funding for lead replacement. Contact the City of Rockville to ask whether they have a replacement program and whether you qualify.
