Where the water comes from

Britz/Colusa draws water from 1 surface water intake.

Annual water quality report

Britz/Colusa 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 Britz/Colusa for a copy.
