Specific Requirements.

In addition to the Core Knowledge and Skills the Water Treatment Technician will have one of the following sets of specific Knowledge and Skills dependant on their individual job roles and the discipline they are following:

Water Treatment Technician

Water treatment technicians are responsible for surveying the construction of water systems and the specific use of water within these systems. The Technician will then advise and recommend suitable treatment programmes, both chemical and physical, to minimise corrosion, scale and microbiological growth in order to maximise the system/process efficiency and system plant life.
