Where the water comes from
Mesa WSD draws water from 3 wells (1 of them for emergency, seasonal or other part-time use).
Annual water quality report
Mesa WSD 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.
Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Mesa WSD for a copy.
