Grade 3 sample question

Program evaluation: cost of water saved · an original practice item written only from publicly available sources, not a real exam question

A one-time rebate program costs $120,000. The fixtures it installs save 15 acre-feet (AF) a year for a 10-year life. What is the program's cost per acre-foot saved (ignoring discounting)?

$800
$8,000
$12,000
$120,000

Answer and working

A. $800

Lifetime savings = 15 AF × 10 years = 150 AF. Cost per acre-foot = $120,000 ÷ 150 = $800. $8,000 counts only the first year's savings, $12,000 divides by the life in years alone, and $120,000 is the whole program cost with no savings divided in.

WUEP Candidate Handbook, CA-NV AWWA (v201130)

Topic coverage follows 2020 Certification Candidate Handbook - Water Use Efficiency Practitioner (California-Nevada American Water Works Association, issued 30 November 2020). 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.
