Vermont split its wastewater licensing off to a different state office in 2017, but the technical bar stays the same: your certificate grade has to match the facility class.
Being a contract operator means carrying responsible charge for systems you don't own, on rules that change at every state line. This page holds what this state actually requires, cited to the current rule text and dated. If you're earlier in the journey, start with the guides below.
Vermont's drinking water rule uses the term "Designated Certified Operator," or DCO. The Water Supply Rule never formally defines "contract operator" as its own term, though the state's own guidance uses that phrase all the time. Wastewater is the opposite: "contract operations" is an officially defined term in the WWTF Operator Certification Rule, meaning "the operation, management, and/or maintenance of a wastewater treatment facility by someone under contract or agreement other than the owner."
Drinking water systems fall into 5 classes (1 through 4, plus Class D for distribution-only systems), and Class 1 splits further into A and B. Wastewater facilities fall into 5 grades (I through V) using a point system that scores treatment type, disinfection, and design flow, capped at 215 points. Either way, the certified operator in charge needs a certification equal to or higher than the system's class.
Drinking water certification stays entirely with the Department of Environmental Conservation (DEC). Wastewater technical rules stay with DEC too, but the actual license now gets issued by the Secretary of State's Office of Professional Regulation (OPR) - a split that took effect January 1, 2017.

On drinking water, Vermont's term is Designated Certified Operator (DCO) - "in responsible charge." Every public water system has to have one "available at all times" (Water Supply Rule, sections 12.1 and 12.2.1.2). On wastewater, the role is called Chief Operator: someone "designated by the owner" to make the decisions that affect wastewater quality or quantity. The backup role is Assistant Chief Operator, who has to hold a certificate no more than two grades below the facility's class.
Naming a DCO is a written filing. The owner (or an authorized representative) signs a form provided by the Secretary and submits it for review. In practice, DEC's Officials Contact Form is the working document owners use to name both the operator and any backup.

Vermont splits WW governance uniquely: DEC (under the Secretary of Natural Resources) still writes/administers the technical classification-and-grading rule (facility point system, grade requirements, training-course pre-approval, examinations) for wastewater operators, but statutory licensing authority (issuing/renewing the actual license, discipline, the professional roster) was transferred to the Secretary of State's Office of Professional Regulation (OPR) effective 2017-01-01 under 26 V.S.A. chapter 99. The WWTF Operator Certification Rule we reviewed is dated 2014-09-25, i.e., pre-dates the 2017 OPR transfer, so its licensing-administration mechanics (Section 5/6 application/issuance steps) describe the pre-2017 DEC process; the technical grading/classification content (Table 1, Appendix A, chief/assistant-chief grade-matching) should still be authoritative since DEC 'continues to review/approve wastewater courses' and sets technical standards per the FG row, but the licensing procedure steps may now run through OPR's own online system rather than the Section 5/6 text verbatim. DW stays entirely with DEC (no split).
Drinking water: when a DCO leaves, the owner has to notify the Secretary in writing within 24 hours, then name a new DCO within 15 days (Water Supply Rule, sections 12.2.1.2 and 12.3.2). Vermont doesn't file a separate "contract" with the state - the designation form is what DEC actually sees - but DEC's guidance recommends keeping contract terms to around three years, with clear renewal, termination, and insurance language.
Wastewater: operators file a certification application on a Department-approved form. But the rule text we reviewed doesn't set a matching deadline for reporting a new or changed Chief Operator the way the drinking water side does.

Vermont sets no cap on how many systems a Designated Certified Operator can serve, and no cap on how many facilities a Chief or Assistant Chief Operator can cover. We checked the Water Supply Rule's responsible-charge and availability sections and the WWTF Operator Certification Rule's staffing sections. Both regulate through certification grade matching the system's class and a one-hour availability standard, not a system count or distance limit.

Vermont doesn't set a fixed visit schedule on either side. Drinking water requires the DCO to visually inspect the source, source-water protection area, storage, and chemical addition systems "at an appropriate frequency" - based on the system's design, location, risk, and its O&M Manual, not a fixed number - plus an inspection within 24 hours of any failure that threatens public health. Wastewater takes a stricter approach instead: "a certified operator shall be present at a treatment facility when any operational activity is being undertaken" (WWTF Operator Certification Rule).
Being "available" runs on a clock. Drinking water requires the DCO be "on site or able to be contacted as needed to initiate the appropriate action within one hour" whenever an issue comes up - so remote or off-site operation looks allowed, as long as that one-hour response holds (Water Supply Rule). Wastewater's rule about being present during operational activity is stricter on paper, but it says nothing about passive SCADA or telemetry monitoring outside of active tasks. The facility-classification point system does count SCADA/DCS as a scoring factor for a facility's grade, but that only affects the grade - it isn't a rule about how you're allowed to operate. Confirm current SCADA-based remote-monitoring expectations directly with DEC before you build a plan around this gap.

Wastewater rule text puts the certification requirement on the people doing the work, not the business itself: "Employees of businesses that provide contract operations services shall be certified in accordance with this Rule" (WWTF Operator Certification Rule). We didn't find any separate state business-registration or bonding rule specific to contract-operation firms.
On drinking water, DEC's guidance recommends - but doesn't require by rule - that a contract include comprehensive general liability insurance for the contract operator, and that contract terms run no longer than about three years with clear termination and notice language. Those are recommendations, not codified requirements, so build your own agreement with DEC's checklist in front of you.

Most states don't make liability insurance a condition of holding a license. Carry it anyway. EPA's operator hiring guide puts it on the short list of questions every board should ask a contract operator: do you have liability insurance, and does it name the utility?
The reason is simple. You are making calls that affect public drinking water on systems you don't own. If something goes wrong, an uninsured operator puts the board's whole trust in you on the line, and boards that have been burned know to ask. Showing up to the first conversation with coverage in hand, and the certificate to prove it, closes the question before it opens. Talk to an insurance agent who handles utility contractors; policies that name each system you serve are the norm in this business.
Every system you operate on one map, with the records, work orders, and compliance schedule your crew actually uses. We run our own contract operation on it, so the demo is the real thing, not a sandbox.
