2.  I have a lead service line - what's next?



PWSA has used curb box inspection results, PWSA historical records, and the age of water mains to determine the location of lead service lines throughout the City of Pittsburgh and Millvale.


PWSA must comply with federal law to replace a portion of the lead service lines in its water system. The 2018 lead service line replacement program includes replacement of the PWSA-owned service lines, and provides limited funding to replace lead lines identified on private property. Recent changes to state law now allow PWSA to perform lead service line replacements on private property as part of the replacement program, preventing potentially harmful partial lead service line replacements.


Those eligible to receive a full lead service line replacement under PWSA’s 2018 contract will receive a letter and agreement approximately 45 Days before replacement. No parking signs will be posted 1-2 weeks before construction, and 48-hour notice door hangers will be placed at affected properties.


If you have misplaced the agreement PWSA sent you via mail, you can print another copy here.


If both portions of your lead service line are lead and you wish to coordinate replacement with PWSA immediately, contact the Lead Help Desk at 412.255.8987 or email at


A guide for flushing your household plumbing after a lead service line replacement:

After construction on your water service line, it is important that you follow these instructions to thoroughly flush your household plumbing for at least 30 minutes before anyone in your house drinks water or turns on the hot water in any faucets. This will help minimize your exposure to lead in your water.


For more information about water safety, usage of NSF-approved water filters, and other questions you may have, check out, call the Lead Help Desk at 412-255-8987, or email



Having no lead service line does not necessarily mean your water is lead-free. Lead can also be found in the following internal plumbing materials:

  • interior lead pipe
  • interior galvanized pipe (especially if there was, or is, a full or partial lead service line)
  • interior copper pipe with lead soldered joints (installed prior to 1988)
  • interior plumbing fixtures (purchased or installed prior to January 2014 before the effective date of new definition of “lead-free”)


You can test your internal plumbing materials using the lead infographic listed at the top of the page, or you can buy lead test swab at most home improvement stores. 



3. Are there financial programs to help customers replace private lead lines? 



The Urban Redevelopment Authority (URA) is offering a loan up to $10,000 at 3% interest for qualified PWSA customers who want to replace the private portion of a lead service line. To learn more about the program and to see if you qualify, check out the ROLL fact sheet here



4. Other programs



You can get a pitcher-style filter to remove lead from drinking water through the City of Pittsburgh's Safe Water Program. Discount coupons are available here



  • Until you replace the entire lead service line, continue to take steps to reduce your exposure to lead in your water:

    • Run your water to flush out lead.

      • If you haven’t used your water for several hours, run your cold tap for one minute before using for cooking or drinking.  Homes with longer lead water service lines may require flushing for a longer period of time. Using toilets, washing clothes, showering, or doing dishes before you drink from your tap are all ways that you can flush your service line without wasting water.

    • Use cold water for cooking and preparing baby formula.

      • Lead dissolves more easily in hot water. Do not drink, cook with, or make baby formula using hot water.

    • Do not boil water to remove lead.

      • Boiling water will not reduce lead.

    • Look for alternative sources or treatment of water.

      • Purchase an NSF water filter that is certified to remove lead.

      • Customers can also choose to drink bottled water.

    • Identify if your plumbing fixtures contain lead.

      • There are commercially-available lead check swabs that can detect lead on plumbing surfaces such as solder and pipes. Consider having lead-containing pipes and fixtures replaced.

    • Get your child’s blood tested.

      • If you think your child may have been exposed to lead, talk to you doctor about testing your child. Remember that Allegheny County requires all children to be tested for lead exposure at approximately 9-12 months, and again at 24 months. If you had your child tested recently, retesting should be discussed with your doctor.
