Very Small Water System Operator study guide
Very Small Water System Operator · Work through your exam, one topic at a time.
The Very Small Water System Operator credential is a state-issued certification for the individuals who run and maintain small public drinking water systems. The California State Water Resources Control Board administers the drinking water operator certification program through its Division of Drinking Water, and its website lists Drinking Water Treatment & Distribution System Operators among its most-visited program pages alongside the Operator Certification Exams page. This study platform's question set is organized around four equally weighted domains: Drinking Water Treatment, Drinking Water Distribution, Very Small Water System Operations, and Water System Regulations and Public Health. Each domain accounts for 25 percent of the question pool, so candidates should prepare broadly rather than concentrating on treatment alone. The Very Small Water System Operator study guide has 4 sections and about 1,007 words.
01Drinking Water Treatment for Very Small Systems
A very small system still performs the same unit processes as a large one: source protection, coagulation/flocculation and sedimentation (if surface water), filtration, and disinfection. Know what each barrier removes: coagulation targets turbidity and natural organic matter; filtration removes particles and some pathogens; disinfection inactivates bacteria and viruses.

Distribution protects the quality produced at the source. Key ideas: maintaining positive pressure to prevent backflow and intrusion, keeping an adequate disinfectant residual throughout the system, preventing cross-connections, and managing storage.

Very small systems are operationally lean: often one certified operator, limited instrumentation, and part-time oversight. Candidates must understand routine monitoring, recordkeeping, sampling schedules, and contingency planning.

Regulations protect public health through maximum contaminant levels (MCLs), treatment techniques, monitoring requirements, and public notification. Know the categories: microbiological (e.g., total coliform, E.
