About Water Operator Guide
A free decision and study tool for people trying to enter or advance in U.S. drinking-water and wastewater operations.
What this site is
Water Operator Guide organizes certification routes, exam preparation, operator math, and career steps using direct links to state agencies. It does not issue credentials or make eligibility decisions; those decisions remain with the relevant state program.
What problem this site solves
State requirements are often split across program pages, forms, exam vendors, training lists, and experience tables. Water Operator Guide turns that fragmentation into a practical sequence: choose the work, open the controlling state source, build the record, study the operator discipline, and connect certification to a real job.
What this site does not do
We do not issue certificates, approve experience, sell courses, schedule state exams, guarantee eligibility, or reproduce protected exam questions. State agencies and their authorized vendors make those decisions.
Why no account is required
Core tools work in the browser. Local storage saves a route, checklist, practice history, missed questions, and math score. Export/import exists for device changes; there is no pretend cloud sync.
