SWT MAIN SYSTEM Lead Service Line Inventory
SWT MAIN SYSTEM serves approximately 14,500 people in Pennsylvania. Like all water utilities across the US, it is required to maintain an inventory of lead service lines—the pipes that connect homes to the water main—and share that information with customers.
What we know about SWT MAIN SYSTEM's lead service lines
The utility has not yet published a detailed lead service line inventory that is publicly available through our directory. This means information about how many lead, galvanized, or non-lead service lines serve this system is not currently accessible online.
This does not mean the utility has no lead service lines or that there is no risk. It means the data has not been shared in a public, searchable format.
Why this matters
Lead service lines pose a health risk, especially to young children and pregnant people. Even low levels of lead exposure can affect child development. If your home was built before the 1980s, there is a meaningful chance your service line contains lead—particularly if you live in an older neighborhood.
The federal government now requires water utilities to identify and eventually replace all lead service lines. Pennsylvania utilities are working toward these goals, though timelines vary.
What you should do right now
Contact SWT MAIN SYSTEM directly to ask about your specific address:
- Ask if your service line is lead, galvanized steel, or another material.
- Request information about any lead line replacement programs or assistance.
- Ask when they expect to publish or update their full inventory.
You can usually find contact information on the utility's website or your water bill.
Protecting your family in the meantime
- Have your water tested. Many utilities and health departments offer free or low-cost lead testing.
- Run cold water first. Let water flow for 30 seconds before drinking or cooking if water has been sitting in pipes (especially first thing in the morning).
- Talk to your pediatrician if you have young children. They can order blood lead level tests and discuss other ways to reduce exposure.

Frequently asked
How do I know if my water has lead?
You cannot see, taste, or smell lead in water. The only way to know is to test your water. Contact your local water utility or health department—many offer free or low-cost lead testing kits.
Is lead service line water safe to drink?
Lead can leach from service lines into drinking water, especially in homes with acidic water or if water sits unused in pipes. There is no truly safe level of lead, especially for children. Testing and the steps above (running water first, using a filter) reduce risk.
What should I do if my service line is lead?
Contact your water utility to ask about replacement programs, rebates, or financing assistance. In the meantime, run cold water for 30 seconds before drinking or cooking, and consider using a certified lead-reducing filter. Talk to your doctor about your family's risk.
Is my utility required to replace lead service lines?
Yes. Federal law requires all water utilities to identify and replace lead service lines on a set timeline. Contact SWT MAIN SYSTEM to ask about their specific replacement schedule and whether your address qualifies for assistance.
