You do not need any formal qualifications, but a good general education is useful.
You might enter through a Scottish Water Technical: Water Industry Modern Apprenticeship.
For entry to the Scottish Water four year Technical Apprenticeship you usually need at least five subjects at National 4 or 5, preferably including English, Maths and science subject. Two Highers or relevant technical qualifications or experience are an advantage.
You may need a driving licence or be working towards one.
There is no age restriction for entry, but if you have to operate machinery you must be over 18.
The Scottish Water Modern Apprenticeship leads to a relevant SVQ at SCQF Level 6, a National Progression Award (NPA) and HNC in Water Operations.
You could train on the job and attend college on a day release basis.
There are good opportunities later for progress into technician or incorporated engineer level work, or into promoted posts as a supervisor, a water inspector, an area superintendent or controller or a trainer for new staff.
