Water Distribution Operator Exam Prep
Prepare for distribution-system questions involving pipe flow, pressure and head, pumps, storage, cross-connection control, and water-main disinfection. The resources below connect each concept to a worked tool and a targeted practice set.
What this exam domain covers
- Pipe velocity using Q=AV and consistent diameter units
- Pressure-to-head conversion and Hazen-Williams friction loss
- Backflow prevention assemblies and field-test criteria
- AWWA C651-23 continuous-feed water-main disinfection
- Storage-tank volume, net fill rate, fill time and turnover
How to use this study path
Review the pipe and pump guide first, then alternate between velocity, head-loss, storage, and disinfection questions. Treat every unit conversion as a written step. Use the linked flashcard after an incorrect answer and return through its direct question link.
Published practice: 100 questions in this domain, with explanations and linked review resources.
