PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard in combination with context expertise standards will be able to operate, monitor and maintain maturation and oxidation ponds to ensure optimal functioning of the ponds. Achieving this unit standard will enhance employability of the learner in both rural and urban contexts. This competence will ensure that the water environment is economically sustained and protected in accordance with legislation and regulations.

    This unit standard has been replaced by unit standard 246441, which is "Maintain maturation and oxidation ponds", Level 1, 2 credits.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 between 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:
    Oral or written questions
    Observation

    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.
