PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard in combination with context expertise standard(s) will be able to explain the elements of the water purification process and the purpose of the works. This competence will enable the learner to assist in the operation of the purification process within the relevant health and safety and legislative guidelines. This competence will equip the learner with knowledge that contributes to the learner`s personal development, which will enhance employability of the qualifying learner in both the water sector and other related jobs.

Integrated Assessment:

When conducting assessments, assessors must ensure that they are familiar with the full text of the unit standards being assessed. Assessors must ensure that the assessment covers the specific outcomes, critical cross-field outcomes and essential embedded knowledge by developing assessment activities and tools, which are appropriate to the contexts in which the learners are working. These activities and tools may include self-assessment, peer assessment, formative and summative assessment. It may be more effective and efficient to assess a number of unit standards together in an integrated way, thus reducing the overall number of assessments and ensuring that commonalities that exist among a number of unit standards are captured in a way that makes sense for assessment.
