Lead service lines in Bellevue, WA

Bellevue's three water systems serve about 321,500 people. Currently, no lead service lines have been identified in inventory data.

What we know about lead in Bellevue's water

Lead enters drinking water when it dissolves from pipes and plumbing materials—not from the water source itself. The most common source is lead service lines, the pipes that connect the water main under the street to your home.

Bellevue's main water provider, Bellevue City of (serving 321,349 residents), has not reported known lead service lines in its current inventory. The two smaller systems—Chinook Water System and R & P Rentals—also show no identified lead lines.

However, "not found yet" is not the same as "none exist." Utilities are required by the EPA to complete lead service line inventories by October 2024. If your home was built before 1986 (when lead solder use ended) or before the 1970s (when lead pipes were phased out), your property may still have lead plumbing that hasn't been cataloged.

Should you be concerned?

Lead exposure, especially for young children, can affect brain development and learning. The CDC recommends testing if you're uncertain about your plumbing. A simple water test costs $20–50 and takes a few days.

If you have a lead service line, you can reduce exposure now by flushing your pipes (running water for 30 seconds before drinking) and using a certified filter. Long-term, replacement eliminates the risk entirely.

Next steps for residents

  • Contact Bellevue City of (or your smaller system) to ask if your address has been surveyed for lead lines. Request a copy of your property's inventory record.
  • Test your water if your home predates the 1980s or you want confirmation. Your utility may offer free or low-cost testing.
  • If you find lead, speak with your utility about replacement programs or rebates—some utilities help fund pipe removal.
  • Talk to your pediatrician if you have young children and are concerned about exposure.
