Where the water comes from

Inchelium Water District draws water from 10 wells (4 of them for emergency, seasonal or other part-time use).

Annual water quality report

Inchelium Water District must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
