The Finance Department is responsible for meter reading and billing services for the 5,000 Water utility customers. The department bills customers every month. See current water rates for City of Sonoma customers. During the period that the Sonoma County Shelter In Place order is in effect, the City will not assess late fees on water bills and will not enforce water service disconnections due to delinquency or nonpayment.
