Payment Options

Due to continued escalation of the federal and state emergency related to the Coronavirus (COVID-19) Pandemic and the recent extension of the Shelter In Place order by the Health Officer of Sonoma County (Order No. C19-03), Town offices will remain closed to the public through December 2020, possibly longer.


PLEASE NOTE:  Town of Windsor offices and virtual operations will be closed during the week of the Thanksgiving holiday from Monday, November 23, 2020 through Friday November 27, 2020. During this time all voicemail, emails and posting of payments will be addressed when staff returns after the holiday. 

If you experience a water emergency during the holiday closure call (707) 838-1000 and you will be directed to the answering service. 

The following options are to make it as convenient as possible to manage your utility account during this time.
