Lead Service Lines in Greensburg, PA

What you need to know

Greensburg's water is served by 13 different water systems, with the two largest—MAWC SWEENEY PLANT (serving 143,000 people) and MAWC YOUGH PLANT (serving 133,000 people)—providing water to most of the area's 313,697 residents.

Lead service lines are pipes that connect the water main in the street to your home. If your line is made of lead, water sitting in it overnight or during periods of low use can pick up lead, especially in homes built before 1970. The good news: lead in water is preventable through flushing and filtration, and you have options to know your status.

What Greensburg's data shows

Our records show that the utilities serving Greensburg have not yet reported confirmed counts of lead service lines to the Pennsylvania Department of Environmental Protection. This doesn't mean there are no lead lines in your area—it means the inventory data isn't publicly available yet. Under federal Safe Drinking Water Act rules, water systems must complete lead service line inventories by October 2024 and report findings to the state.

How to find out about your home

Your water utility is the best source for information about your specific service line. Contact one of the main water systems serving Greensburg:

  • MAWC SWEENEY PLANT (PA5650032): Serves the largest population in the area
  • MAWC YOUGH PLANT (PA5260036): Serves 133,000 residents
  • West County Municipal Authority–McKeesport (PA5020025): Serves 32,644 people

Ask your utility:

  • Whether your address has a lead service line on file
  • If they've completed their lead inventory
  • What testing options they offer

You can also check your home's age and construction records—lead lines are most common in homes built before the 1950s, though they appeared in homes built into the 1980s.

Next steps for residents

  • Contact your water utility to ask about your service line and request a lead inventory report if available
  • Get your water tested if you're concerned; most utilities offer this free or low-cost
  • Flush cold water before drinking or cooking if your home has a lead line (run the tap 30 seconds to 2 minutes)
  • Use a filter certified for lead removal (NSF Standard 53) as a temporary measure while awaiting line replacement

Common questions

Does Greensburg have lead in the water?

Lead in water comes from service lines and pipes, not from the source water itself. Greensburg's 13 water systems have not yet publicly reported their lead service line counts. Your utility can tell you if your specific address has a lead line.

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

Contact your water utility with your address—they should have records from their lead inventory. Homes built before 1950 are at higher risk. You can also look at your home's construction documents or ask a plumber to inspect the line where it enters your home.

Is lead in drinking water dangerous?

Lead exposure can cause serious health issues, especially in children and pregnant people. For specific health concerns, contact your pediatrician or the CDC's guidance on lead in drinking water. The good news is that lead exposure from water is preventable.

What should I do if I think I have a lead service line?

Start by flushing your cold water tap before drinking or cooking, and consider a certified lead-removal filter. Contact your utility about replacement programs—many offer rebates or free replacement of lead lines on your property.
