All sites where recycled water is used are required to designate a recycled water user Site Supervisor. Site Supervisors are required to have appropriate training to assure proper operation of recycled water facilities, worker protection, and compliance with all applicable laws and regulations. To help recycled water users fulfill their training obligations, free classes are currently being offered periodically throughout the year at various locations by the Los Angeles County Sanitation Districts. Visit the LACSD website for a site supervisor training registration form. A recycled water user Site Supervisor represents the owner, tenant, or property manager. The Site Supervisor is designated to be the main person to interact with the District and respond to inquiries, emergencies and participation in inspections and cross connection testing.
