Issaquah Water System Municipal Water Company and CDC
  1. Where does Issaquah Water System water come from?
    Issaquah Water System supplies groundwater to Issaquah Water System.
  2. Does Issaquah Water System test its tap water?
    Yes. Like every public water system, Issaquah Water System must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
  3. How do I contact Issaquah Water System?
    Call 425-837-3470 or visit 670 First Ave. N.E., Issaquah, WA 98027, or use the contact options on the utility’s website.
  4. Does Issaquah Water System water contain lead?
    Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
  5. Is Issaquah Water System water hard?
    Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
