PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard in combination with context expertise standard(s) will be able to ensure the care and optimal functioning of untreated water intakes. This competence will enable the learner to maintain a catchment area, operate and maintain the abstraction works and monitor the quality and flow of raw water required for treatment purposes. This competence will contribute towards the protection of the water environment and a safe water environment for public utilisation. Achieving this unit standard will enhance the efficiency of the qualifying learner and provide foundational learning that will advance his/her own expertise and employability in the water and other related sectors.

    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.


    Assessment Option

    Learners could be assessed using the following methods:
  • Verbal and written questions
  • Observations
  • Evaluation of records and reports


    Definition:
    The term destratification is used when dams turnover through temperature effects in later autumn exposing the bottom water to the surface.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
