PURPOSE OF THE UNIT STANDARD 
This unit standard is intended for persons who have the responsibility to operate the abstract ion of water from water sources.

The person achieving this unit standard will be able to ensure the care and optimal functioning of abstraction structures for untreated water. This competence will enable the learner to monitor adverse activities in a catchment area, operate and maintain the abstraction works and monitor the quality and flow of untreated water required for treatment purposes. This competence will contribute towards the protection of the water environment and ensure 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.

    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    This unit standard replaces unit standard 115884, "Control water intakes", Level 4, 8 credits.

    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.

    Supplementary Notes:

    Definition:

    The term stratification is used when dams turnover through temperature effects in later autumn expose the bottom water to the surface.

    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.
