HORIZONS WEST Lead Service Line Inventory
About this water system
HORIZONS WEST serves 3,454 people in Washington State. The utility draws its water from groundwater sources.
Lead service line inventory status
As of our last update, HORIZONS WEST has not yet completed a lead service line (LSL) inventory. This means the utility has not publicly reported how many homes are connected by lead pipes, or provided a searchable list of affected addresses.
Why this matters: Lead service lines are the most common source of lead in drinking water. If your home was built before the 1980s, there's a meaningful chance it connects to the water main through a lead pipe—even if your home's internal plumbing is copper or PVC. The only way to know for sure is to either see your utility's inventory or have your own service line inspected.
What you can do now
Contact HORIZONS WEST directly to ask:
- Whether your specific address has a lead service line
- When they expect to complete their inventory
- Whether they have interim guidance on flushing or water testing
You can also request a water quality report (called a Consumer Confidence Report). It won't list every LSL but may contain important information about lead testing results.
If you're concerned about lead in your water right now:
- Let cold tap water run for 30 seconds before drinking or cooking (longer if the pipes haven't been used for hours)
- Use cold water for cooking and drinking; hot water can leach more lead
- If you have young children or a pregnant household member, consider testing your tap water or using bottled water for drinking and formula
For health questions, contact your pediatrician or the CDC's lead poisoning hotline (1-844-CDC-1624).
Funding for replacement
We have no record that HORIZONS WEST has received funding under the Bipartisan Infrastructure Law to replace lead service lines. Federal grants and low-interest loans are available; contact your utility to ask whether they plan to apply.

- Call HORIZONS WEST and ask if your address has a lead service line on record
- Request their Consumer Confidence Report (water quality testing results)

Frequently asked
How do I know if my house has a lead service line?
Contact your water utility and give them your address—they may have records. You can also hire a plumber to inspect where the water line enters your home, or request a water test. If your home was built before 1986, lead pipes are more likely.
Is the water from HORIZONS WEST safe to drink?
The utility is required to test for lead and report results in their annual Consumer Confidence Report. Request a copy or ask about the most recent lead test results for your address. Lead risk is highest if you have a lead service line or older indoor plumbing.
How much does it cost to replace a lead service line?
Replacement typically costs $3,000–$25,000 depending on your property and local conditions. Some utilities offer cost-sharing or free replacement programs; ask HORIZONS WEST whether they have funding available.
Can I get the government to pay for replacing my lead service line?
Bipartisan Infrastructure Law funding is available to water utilities for LSL replacement. Contact HORIZONS WEST to ask if they are applying for grants or operating a replacement program.
