How you’d get it

How you’d get this certificate

  1. Zavmo teaches you. You learn the units one-to-one with an AI tutor, on your own work.
  2. You register with an approved centre. That is a college, training provider or employer CABWI Awarding Body has approved to offer this qualification. Zavmo is not an approved centre, so you register with them, not with us.
  3. The centre assesses, and CABWI Awarding Body awards. A qualified assessor at the centre judges your evidence, and the certificate comes from CABWI Awarding Body.

01What it is

logo About Qualifications Courses Centres News Support Contact View our Charity Website Menu

These are the units CABWI Awarding Body registers against this qualification. It is a catalogue, not a syllabus. Which of them you take depends on the combination the qualification requires, and that is set by the awarding body rather than by us. Every unit here is regulated. Zavmo teaches towards them on your own work, and work done here is recognised as prior learning under the agreements we hold.

Zavmo is not an awarding body, is not an approved centre, and is not affiliated with CABWI Awarding Body. It does the teaching and the mapping. CABWI Awarding Body sets this qualification and awards it, and a qualified human assessor makes the assessment decision.

05The credits

The credits, and who awards them

Level 3 credits are regulated, and they are awarded by CABWI Awarding Body rather than by Zavmo. They don’t vanish when a subscription ends or a website closes. They travel to any employer, and Zavmo keeps the map of what you have covered and what is next.

What you would be collecting

Waste Water - Asset ManagementWaste Water - Nuisance ControlWaste Water - Primary TreatmentWaste Water - Regulation and ComplianceWaste Water - Understanding Sludge DigestionWaste Water – Activated Sludge ProcessesWaste Water – Fixed Film Biological TreatmentWaste Water – Nutrient Removal

Each one is a real unit registered against this qualification.

How you’d practise it

You don’t watch this. You do it.

You are not assessed on remembering this. You are assessed on applying it, analysing it, evaluating it and producing something. So that is what the practice is: projects, role play and your own live cases, with a tutor in the room.

The Navigator The Navigator · your what-if tutor Illustration
The Navigator Your plan for “Waste Water – Small Works and Package Plants” assumes the same two people are free in March. What have you seen that makes you slightly uneasy about that?
You One of them has been pulled onto the migration twice already. Probably fine.
The Navigator That is the thread worth pulling. Let us build the version where it happens a third time and find the move that works either way.
The same lesson on the real thing: the conversation in the middle, the thinking ladder on the left, and the criteria each answer is evidencing on the right.
  • Bring your own plan Create

    For “Waste Water – Small Works and Package Plants” you bring the plan you are actually working on, not a case study. Zavmo pulls on the assumptions in it until the weak one shows.

  • Lead it Apply

    “Waste Water - Asset Management” is practised on the team you actually have. You talk through the call you are about to make, and Zavmo makes you say it the way you would say it to them.

This is your Mind Palace on learn.zavmo.ai. Every skill above comes from this role's own record, not an example borrowed from another job. A node lights up when you evidence it, and what you build stays yours between jobs. That is the part a course cannot do.

How you would learn this

One to one, on the work you already do

A tutor sets the task against your own job and marks the reasoning, at your pace. There is no cohort to fall behind.
