Built for the people who keep the water on
Most operators study for certification the same way: a borrowed manual, a stack of photocopies, and a practice test someone printed years ago. Meanwhile the exam is written from a specific published outline, weighted by topic, and heavy on applied math.
Study for Water starts from that outline. Every question is tagged to a topic and weighted the way the exam weights it, so a readiness score actually means something. Math is drilled with fresh numbers each time and a worked solution, because remembering the answer is not the same as knowing the method.
And all of it is free. Every course, question bank, math drill, and timed practice exam is available at no cost to operators, utilities, and departments — no plans and no card.

How courses are written
Each course begins with the published exam outline and reference list for its section. Topics get exam weights, questions get explanations that teach the reasoning rather than restate the answer, and math drills get step-by-step solutions using the same formulas the reference material uses. Courses are reviewed and updated when a new outline is published.
