CA AB1075

Requires the Office of Emergency Services to develop regulations prohibiting privately contracted fire prevention resources from connecting equipment to public water sources during active fire incidents unless approved by incident command or the authority having jurisdiction

Mandates that any approved connection to public water sources must include a backflow prevention device to protect water quality

Preserves community water systems' authority to operate water distribution systems, explicitly stating these regulations cannot alter or interfere with that authority

Builds on existing law requiring private fire prevention resource vehicles to be labeled "nonemergency," prohibited from using emergency lights/sirens, and barred from labeling that suggests emergency personnel or fire department affiliation
