CWEP practice questions - frequently asked questions

Plain answers about how CWEP Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real CWEP exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CWEP exam spans 16 domains: Introduction to General Water Conservation (2%-4%); Policy, Standards, and Regulations (2%-4%); Value of Water and Benchmarking (4%-6%); Water Metering (4%-6%); Water Balance & Audit Approach (4%-6%); Measurement & Verification (3%-5%); Water Treatment (6%-10%); Domestic Plumbing Fixtures (8%-12%); Commercial Kitchen Equipment (5%-7%); Laundry Equipment (6%-8%); Cooling Towers and Steam Boilers (8%-12%); Pools and Other Open Water Bodies (5%-7%); Irrigation (7%-11%); Additional ICI (Institutional, Commercial, and Industrial) Water Uses (5%-7%); Medical, Research, and Lab Equipment (6%-8%); Storm Water Management and Alternative Water Sources (5%-7%). Every practice question on this site is tagged to one of these domains.

The CWEP exam has 100 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
