115893  Demonstrate sound environmental practices in wastewater operations  Level 4  NQF Level 04  7   

PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard in combination with context expertise standard(s) will be able to explain sound environmental practices associated with wastewater operations and demonstrate contamination prevention methods and remedial techniques for spillages. This competence will enable the learner to demonstrate sound environmental practices in compliance with relevant legislation and contribute towards the protection of the environment. In acquiring this competence the qualifying learner will lay a good foundation for future learning and action, and better understand the broader context of own work. Achieving this unit standard will enhance the employability of the qualifying learner in the water sector and contribute to the improvement of community health.

    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 115893, "Demonstrate sound environmental practices in wastewater operations", Level 4, 7 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.
  • Simulation.
