The Los Osos Community Services District provides water service to the Baywood Park portion of Los Osos.  There are three water purveyors in the community of Los Osos so it is important to note where your home is located on the attached map.  The map provides contact phone numbers for each purveyor.

If you are located outside of Los Osos CSD's water service area, you will need to set up water service with S & T Mutual Water Company or Golden State Water Company. Here is their contact information:
