Water & Wastewater Operator Certification in Colorado

Your path to certified in Colorado

1. Meet the board, then meet its contractor. Certificates come from the Water and Wastewater Facility Operators Certification Board inside CDPHE, but day-to-day everything runs through the Colorado Certified Water Professionals office and its portal. Here is the part nobody expects: that office is staffed by Colorado Rural Water Association in Pueblo West, under contract to the board.
2. Clear the MRT gate first. Mandatory Regulatory Training is Colorado's own prerequisite for sitting an exam, getting certified, reciprocating, and every renewal. The state provides free online MRT courses (one water version, one wastewater), each completion good for three years.
3. Climb in order; skipping is not allowed. Five tracks run sequentially: water treatment and both wastewater treatment tracks go D to A, distribution and collection go 1 to 4. Entry needs a diploma or GED plus one month of hands-on time, and an approved course or apprenticeship can substitute for the month.
4. Apply, then schedule yourself. The steps page walks it: $50 application in the portal, about ten business days of review, then $104 to PSI for a test center seat or remote proctoring. Approval buys a 100-day window and up to three attempts.
5. Renew on threes. Certificates last three years: $85, training units scaled to your class (1.2 TUs at entry up to 3.0 at the top, half in your certificate's own category), and a current MRT. Late costs $100 and the restoration window runs two years.

Exams are WPI standardized except the small-system specials, and the math is the most predictable part. The free practice tool drills exactly that; use the 100-day window for logistics, not arithmetic.

Drinking water: Water and Wastewater Facility Operators Certification Board (in CDPHE), via the CCWP office program page

Who runs certification here

Three layers share the work. The board (ten governor-appointed members, including a reserved seat for the rural water association) owns the rules through Regulation 100. The Water Quality Control Division at CDPHE classifies facilities and enforces the operator-in-responsible-charge requirement, with a $300-per-day civil penalty hanging over owners who run unstaffed. And the CCWP office administers applications, renewals, training units, and the portal under contract, run by CRWA staff. Exams come from WPI (the old ABC bank) and are delivered by PSI. The Regulation 100 and policies page is the canonical library.

The grades and what they cover

Five sequential tracks: water treatment (Class D up to A), domestic wastewater treatment (D to A), industrial wastewater treatment (D to A), water distribution (1 to 4), and wastewater collection (1 to 4). Facilities are classified on the same scales, and your certificate must meet or beat the facility's class. Advancement stacks experience (two years for the second rung, three more for the third, four more for the top) with post-secondary education able to substitute for up to half.

The small-system story is Colorado's quiet strength. Class S certificates bundle treatment plus distribution (or wastewater treatment plus collection) for systems serving up to 3,300 people, letting one credential cover a Class D plant and a Class 1 network. Class T covers transient noncommunity systems (think campgrounds) with no minimum experience at all. Both use custom Colorado exams rather than the national bank. Legacy restricted certificates still tie some pre-2001 operators to a single named system.

The exam: logistics, not cramming

Build your operator record in the CCWP portal, document education, experience, and MRT, and apply for the specific exam ($50, nonrefundable). Approval takes about ten business days and opens a 100-day eligibility window with up to three attempts under that one application (a 2024 rule change; it used to be 180 days). Each sitting costs $104 paid to PSI when you schedule, at a test center or by remote proctor.

Remote proctoring has teeth: a detachable webcam for the room scan, no Chromebooks, tablets, touchscreens, or dual monitors. Pass mark is 70 everywhere. Wondering what the questions cover before committing a window? The what's on the exam guide maps it, and WPI publishes need-to-know outlines per class.

Keeping it current (renewal)

Three-year certificates, renewed in the portal for $85 with two requirements: training units and a current MRT. The TU table on the renewal page scales by class (1.2 for D/1/T, 1.8 for C/2/S, 2.4 for B/3, 3.0 for A/4, where one TU equals ten contact hours), at least half approved for the specific certificate category, all earned inside the three-year validity period with no carryover.

Late renewal adds a $100 fee, the restoration window runs two years after expiration, and operating on an expired certificate is prohibited outright. The approved course catalog filters by category, TU value, and delivery method, which makes closing a TU gap a search problem rather than a phone-tag problem.

Training and continuing education

Colorado Rural Water Association anchors small-system training with online self-paced and in-person courses, and runs a two-year, federally recognized apprenticeship that the rule explicitly accepts in place of entry experience (employer sponsorship required). The state's free MRT courses cover the regulatory layer. Rocky Mountain Section AWWA adds the water-side conference circuit, and the TU catalog above is the master list of what actually counts. One sequencing tip: take MRT early, since it gates the exam itself, not just the certificate.

Reciprocity

Out-of-state operators apply through the portal under Board Policy 13-1 for $150. If your home state used a Colorado-comparable exam, you certify without retesting; operators from custom-exam states can at least skip Colorado's sequential-ladder requirement. Everyone still has to meet Colorado's education and experience bars for the class sought, plus MRT. Decisions land in about ten business days and can be appealed to the board in writing within 30 days. Details on the out-of-state page.

Where to get help (small systems)

• Colorado Rural Water Association, crwa.net: training, the apprenticeship, circuit-rider help, and the same people who staff the certification office, so questions land close to the answer.
• The operator lookup verifies any certificate by name or number, with class and expiration.
• The CCWP program hub collects every path, form, and policy in one place.
• The Water Quality Control Division handles facility classification questions, which decide what certificate your system actually needs.

Running a system in Colorado

The oversight and funding picture, short version.

Rate regulation. The Colorado PUC approves rates for investor-owned water companies only, a small club. Municipal systems, water districts, and water and sanitation districts set rates through their own boards, outside PUC reach.

Funding. The revolving funds run as a three-agency partnership documented on the SRF page: CDPHE manages environmental review and project management, the Department of Local Affairs handles credit work, and the Colorado Water Resources and Power Development Authority manages the money (Drinking Water Revolving Fund and Water Pollution Control Revolving Fund, with 2025 direct-loan rates between 1.50 and 3.50 percent over 20 to 30 years; private nonprofit water systems are eligible on the drinking water side).

Mutual aid. CoWARN is the statewide mutual aid network with several hundred member utilities and the usual rule: the agreement only helps if you signed it before the wildfire.
