The data in this map is compiled from multiple sources. Sources include historical records, field inspections, permits, and material tests of one section of the service line during meter upgrades. These records will be updated over time as we gather additional information. We reserve the right to alter, amend, or stop the display of these maps and records at any time. We are required by state and federal law to make these records available to the public.

Understanding your Service Line

To assess the overall service line material, PWD reviews material information from two points along your service line. Based on the PWD’s current records, the property map look-up tool will indicate the material make-up of your service line:

  1. Material in the section between Main and Curb Stop: Portion of the service line closest to the street
  2. Material in the section between Curb Stop and Meter: Portion of the service line closest to the property
The service line connects the water main under the street to the water meter in the customer's basement. There is typically a "curb stop" in the middle that can be accessed from a port in the sidewalk.

What is the Curb Stop?

The curb stop is a valve located near the edge of your property, often in the sidewalk or just beyond the curb.

While the curb stop is sometimes worked on by PWD during routine maintenance or water main upgrades, it remains part of your service line. Since the pipe material can change at the curb stop, checking this point helps PWD determine whether your service line contains lead.

As material can differ along the length of the service line, PWD evaluates the material combination at each property, and determines the service line overall material status. To categorize the service line as Non-lead, PWD must verify the service line material type along at least two points of the service line. *

If the map indicates that you have a lead service line, visit the Lead Plumbing & Water Quality page for more information on reducing lead exposure and replacing your lead service.

* Service line categorization meets the Pennsylvania Department of Environmental Protection criteria.

Water Service Line Materials

Remember: Service lines in Philadelphia belong to the property owner.

Checking two points

To categorize a service line, we’re required to check the material at two points along the length of the line. PWD recently checked the service line material for hundreds of thousands of properties at the point nearest the water meter. That test provided one point of information.

Different materials at different points?

To assess the overall service line material, PWD reviews material information along two points of your service line. Your service line is categorized based on the overall material.

Lead was used in the past because it is soft and can be bent. Lead service line installation decreased after the 1950s as harmful health effects became clear.

Having lead pipes does not necessarily mean you have lead poisoning or significant health complications from lead. However, it is important to take steps to reduce potential exposure.

Galvanized metal pipes can corrode. Over decades, any lead from a property’s plumbing can accumulate on the corroded walls of galvanized pipes.

Many service lines are categorized like this if we have partial or incomplete records for the service line material. Previously, we referred to these lines as “unknowns”.
Learn more about incomplete records →

If your service line is categorized as “non-lead”, it is likely made of plastic or copper. These materials are commonly used because they do not contain lead. Learn more about non-lead service lines →

If you have specific concerns about lead in your drinking water, you can request a free water test from the Philadelphia Water Department to check the levels at your tap. Learn more and request a test →

Why did we create this map?

Old lead service lines are a challenge across the country. Even though these lines don’t belong to the City of Philadelphia, we are committed to supporting the removal of water service lines that contain lead. To meet this challenge, cities need to understand the number and location of these lines. The map and records will inform plans for future lead service line replacement efforts.

It’s the law:  We’re required by Federal and State law to make this information available to the public. This law applies to every water utility in the United States. There is a national effort to remove lead service lines from all properties. Sharing this information is a key step in this important work.

Where did the map information come from?

The information is compiled from multiple sources. Sources include historical records, field inspections, permits, and material tests of one point of the service line during meter upgrades or conservation assistance.

However, no materials identification method is 100% accurate.

Further work may be required to confirm and verify the materials at more points along a service line.
