About

Clear guidance, with the regulator kept in view.

Water Operator Guide is an independent reference utility for U.S. drinking-water and wastewater operators.

What we do

We translate official certification and renewal materials into practical state guides. Each guide identifies the controlling agency, credential structure, renewal cycle, continuing-education rules, and official next step.

How we research

Regulatory claims are based first on state agencies, official rules, certification manuals, forms, and portals. Every state guide retains its source links and a human verification date. When official evidence is ambiguous, we say so.

What we do not do

We are not a regulator, certification authority, training provider, or exam-guarantee service. Requirements change, and operators should confirm material decisions with their state certification authority.
