OCWA Lead Service Line Inventory
OCWA serves about 350,000 people in New York. Like many older water systems, some homes are still connected to the water main through lead service lines—pipes that can leach lead into drinking water, especially in homes built before 1986.
What OCWA has found
OCWA has inventoried 39,209 service lines so far. Here's what they know:
- 17,253 confirmed lead lines
- 5,237 non-lead lines
- 16,719 lines of unknown material
The unknown lines are the ones that still need investigation. They could be lead, or they could be copper, plastic, or galvanized steel. Until tested or replaced, it's safest to assume they might contain lead.
Why this matters
Lead service lines are one of the largest sources of lead in tap water. Even small amounts of lead exposure can affect children's brain development and learning. If you live in an older home (pre-1980s), your line is more likely to be lead.
The good news: lead from service lines can be reduced or removed. You have options, from point-of-use filters to full line replacement.
What to do next
First, find out if your home has a lead line. Contact OCWA directly. They may have your service line material on record, or they can tell you how to request a test or inspection.
If your line is lead or unknown:
- Ask OCWA about their replacement program and any financial assistance available
- In the meantime, use a water filter certified for lead (NSF/ANSI 53), or let water run cold for 30 seconds before drinking (cold water picks up less lead than hot)
- Have young children's blood lead tested if you're concerned
For health questions, talk to your pediatrician or call the CDC hotline at 1-800-232-4636.
Next steps for residents
- Contact OCWA to learn your service line material
- Check if you're eligible for line replacement help or rebates

Frequently asked
How do I know if I have a lead service line?
Contact OCWA with your address. They can check their records or arrange for a visual inspection. Lead lines are dull gray and may have solder joints; copper is reddish-brown. If unsure, have a plumber test a sample.
Is the lead in my water dangerous?
Lead in drinking water poses real health risks, especially for children under 6 and pregnant people. Talk to your pediatrician or doctor about your specific situation. The CDC has more information at cdc.gov/lead.
Can I reduce lead in my tap water right now?
Yes. Use a water filter certified NSF/ANSI 53 for lead, or flush cold water for 30 seconds before drinking. These are temporary steps while you work with OCWA on longer-term solutions like line replacement.
Does OCWA help pay to replace lead service lines?
Contact OCWA directly to ask about replacement programs and financial assistance. Many water systems now offer rebates or grants funded through state or federal programs.
