NV Water/Wastewater Operator study guide
NV Water/Wastewater Operator · Work through your exam, one topic at a time.
Nevada Drinking Water Operator Certification and Nevada Wastewater Treatment Operator Certification are the two operator credentialing tracks administered by the Nevada Division of Environmental Protection (NDEP) through its Operator Certification program. NDEP maintains separate Drinking Water and Wastewater operator certification pages, plus an Operators Forum, a Training/Upcoming Events page, and the publication Water Lines. The credential is for people who operate or supervise public drinking water systems or wastewater treatment and collection facilities in Nevada, and for candidates preparing to move into those roles. Because the two tracks are administered separately, a candidate should confirm the requirements for the specific track and grade before applying. Topics on this exam: Drinking Water Treatment and Distribution and Wastewater Treatment and Collection. The NV Water/Wastewater Operator study guide has 2 sections and about 742 words.
01Drinking Water Treatment and Distribution
This domain tests how Nevada public water systems protect source water, treat it to primary and secondary standards, and move it through the distribution system without losing quality. Expect process-control math, disinfection and CT, sampling rules, cross-connection control, and Nevada-specific contaminants such as naturally occurring arsenic. Public water systems in Nevada are regulated by NDEP's Bureau of Safe Drinking Water under NAC 445A and the federal Safe Drinking Water Act. Know MCLs: arsenic 0.010 mg/L (10 µg/L), nitrate 10 mg/L as N, and the total coliform and E.

This domain tests how Nevada collection systems and wastewater treatment plants protect public health and receiving waters. Expect collection-system hydraulics, lift stations, infiltration/inflow, secondary treatment, disinfection, solids handling, NPDES permit limits, and operator math. Collection: gravity sewers need adequate slope and velocity (often about 2 ft/s minimum for self-cleansing); lift stations use wet wells, pumps, force mains, and air or vacuum relief. Control grease, roots, and H2S corrosion; confined spaces require entry permits and gas testing.
