HIGHLINE WATER DISTRICT Lead Service Line Inventory
About this water system
HIGHLINE WATER DISTRICT serves about 100,170 people in Washington State. Like all US water utilities, it is required to maintain an inventory of lead service lines—the pipes that connect homes to the main water line—and report this information to the state and EPA.
This page shows what we know about HIGHLINE WATER DISTRICT's lead service line inventory status. The data comes from public records and utility disclosures.
Current inventory status
As of now, HIGHLINE WATER DISTRICT has not published a complete lead service line count in public records that we can access. This does not mean the utility has no lead service lines—it means the inventory data is either still being gathered, not yet made public, or reported in a format we haven't indexed yet.
Why this matters
Lead service lines are the most common source of lead in drinking water for homes built before 1986. Even low levels of lead exposure can affect children's development. If your home was built before the late 1980s and you're on a municipal water system, there's a reasonable chance your service line contains lead or lead-bearing materials.
What you can do now
Contact your utility directly. HIGHLINE WATER DISTRICT can tell you:
- Whether your specific address has a known or suspected lead service line
- Results of any water testing they've done at your meter
- Whether they have a replacement program or financial assistance
- How to get your water tested if you're concerned
You can also request their Lead Service Line Inventory or Lead and Copper Rule compliance reports, which utilities are legally required to maintain and share with the public.
Get your water tested. A simple test costs $20–50 and takes a few days. If lead is present, you have options: flushing protocols, point-of-use filters, or replacement.
Talk to your pediatrician or local health department if you have concerns about past or current exposure, especially if children under 6 live in your home.

Frequently asked
How do I know if I have a lead service line?
Call your water utility—they should have records of your service line material. If records are incomplete, a plumber can also inspect the line where it enters your home. It's usually in the basement or crawl space.
Is lead in water dangerous?
Lead has no safe level of exposure. It's especially harmful to young children and pregnant people. Talk to your doctor or pediatrician about testing and risk, especially if you have children under 6.
What if my water tested positive for lead?
Use bottled water for drinking and cooking until you've addressed it. Common solutions include flushing the line, installing a filter, or replacing the service line. Your utility may offer replacement programs or rebates.
Does boiling water remove lead?
No. Boiling actually concentrates lead. Use a certified filter (NSF/ANSI 53) or bottled water if your water tests positive.
