As an essential business, MCSD has continued to be open during this precarious time. It has come to our attention that one of our staff members has tested positive for COVID-19. It is not anticipated that there was any Public exposure due to this. However, the MCSD office will be closed to the Public except for advance appointment only until further notice. Utility payments must be made through the website at www.mcsd.com, USPS (mail), or drop box located next to the front door at 1656 Sutter. Please call (707) 839-3251 to make an appointment.
