Water Service Line Inventory Continues Throughout The District
Identifying the Water Lines in Your Home
In December of 2021, the U.S. Environmental Protection Agency (EPA) announced changes to the Lead and Copper rule to ensure that any existing lead water service lines are identified, removed, and replaced. The Greenlawn Water District embarked on an aggressive data collection effort to confirm the material used curbside, and within your home or business.

Please call the District office at (631) 261-0874 to schedule an appointment for one of our service operators to inspect your water service line at the first point of entry to your home or business.
Or if you would prefer to self-inspect your water service line, please review the questions in the form at the link below, complete the form and submit your results. Examples of what to look for and how to identify your service line material are depicted in the questionnaire.
Checking Your Water Service Lines: Self-Certify
The District’s water mains and lines are not made of lead; however, it is important to check your water service lines in your home.
WHAT YOU NEED TO SELF-CERTIFY:
- Magnet
- Sandpaper, file or any object that can be used to scratch the pipe
- Cellphone
STEP 1: Locate the water meter to determine the location of your water main, the pipe that enters your home or business from the outside.
STEP 2: Inside, carefully scratch the pipe’s surface with sandpaper to expose the surface if the pipe is painted.



STEP 3: Identify the metal. If it is silver, use the magnet to determine if it’s lead or steel.
STEP 4: Use your cell phone to take a photo.
STEP 5: Submit your results
