PassOperator: Water and Wastewater Exam Prep

passoperator.com Visit website

Editorial interest 73/100 Selection signal · not a rating of the site

A focused exam-prep site for water and wastewater operators, with worked math examples, free resources, and a planned practice product.

Landing page captured for the 2026-10-25 issue.

For: Class I and II water and wastewater operator exam candidates
Worth noticing: The site says its code checks numeric answers against units, targeting a specific weakness it identifies in some exam answer keys.

Field notes

The worked example converts daily flow to an hourly rate before dividing clarifier volume by flow, and labels the result in hours. The page attributes its Maryland pass-rate figures to Board of Waterworks and Waste Systems Operators minutes from May 2019. Its listed rollout separates treatment exams from distribution and collection, with different stated access dates for those groups.
