The national licensing exam for civil engineers practising in water resources and environmental engineering, and one of five discipline options under the Professional Engineer (PE) Civil exam. It is now a single computer-based exam with one combined topic list, not a separate depth section bolted onto a breadth paper. This is engineering licensure rather than operator certification — the exam asks you to size and design the works an operator then runs, and passing it is a step toward a PE licence, not a plant certificate.

Question counts per knowledge area are published as ranges and the twelve areas below are the published headings. On currency, checked 2026-09-12 and corrected: an earlier note here warned that the April 2027 specifications give this outline a limited shelf life. That is wrong, and the sibling Construction entry has had it right since it was built. Both the April 2024 and the April 2027 Water Resources files were extracted and compared, and outside the design-standards page the only difference is the page title dropping the word CBT. Every one of the twelve areas, every subtopic and every question range is identical, and the specification page inside the 2027 file still carries its own Effective Beginning April 2024 stamp. What changes in April 2027 is the supplied reference set, from two standards to seven: Ten States Standards Water Works moves from the 2018 to the 2022 edition, and 29 CFR 1926, the USACE slope stability manual, HDS-5, HEC-14 and the UFC dewatering manual are added. So the outline does not expire; individual items can, and the one to watch is any item pinned to a Ten States edition, of which there are currently none. The next real specification revision is unscheduled, NCEES saying only that specifications change every five to seven years and are posted six months ahead. The other currency point: the 480-minute mock timer is a PUBLISHED figure, not this app's estimate, which an earlier note here got wrong. The NCEES Examinee Guide breaks the nine-hour appointment into 2 minutes of non-disclosure agreement, 8 minutes of tutorial, 8 hours of exam and a 50-minute break, and the ncees.org civil page repeats it, so 480 minutes of exam time is the Council's own number. The sibling Construction track's entry has said so correctly since it was built.
Topic coverage follows PE Civil — Water Resources and Environmental Exam Specifications, effective April 2024 (National Council of Examiners for Engineering and Surveying). Practice questions are written only from publicly available sources (that outline and the regulations and references it cites); they are not real exam questions, which are confidential. Check current application requirements, fees and exam dates on the certifying body's own page: official certification page.
Questions, flashcards, and explanations are AI-written from publicly available sources only: the exam content outlines and candidate materials each certifying body publishes without restriction, and the regulations and technical references they cite. No confidential material is used, including actual exam questions, recollections of any exam sat by the author, or any handbook or document released under a confidentiality agreement. Content is then put through repeated review — regulatory values checked against primary sources, every calculation recomputed, and errors corrected — plus spot checks by the author, who holds California water operator certifications and a California civil engineering licence. Those spot checks are sampling, not a professional review: nothing here is stamped, sealed, or offered as engineering advice, and not every item has been individually verified, so mistakes can still slip through.
