PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard will be able to explain the purpose of trenchless technologies, the different types and the advantages and disadvantages of each type. This competence will enable the learner to make recommendations when trenchless technologies would be appropriate based on calculations, evaluations and analysis of data. This competence will enable the learner to monitor contractors more effectively thus ensuring minimal disruptions to customers. Achieving this unit standard will form the foundation for specialising in trenchless technologies and will enhance the employability of the qualifying learner.

  • Communication at NQF Level 3.
  • Mathematical Literacy at NQF Level 3.
  • Knowledge of wastewater reticulation systems and engineering drawings. 
    		•

    UNIT STANDARD RANGE 
    Types of trenchless technologies:
  • Pipe jacking, drilling, in situ lining, pipe cracking, slip lining, CCTV.

    Site preparation:

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner or moderating the assessment of a learner against this unit standard must be registered as an assessor with the relevant ETQA.
  • Any institution offering learning that will enable the achievement of this unit standard must be accredited as a provider with the relevant ETQA.
  • Assessment and moderation of assessment will be overseen by the relevant ETQA according to the ETQA`s policies and guidelines for assessment and moderation.
  • Moderation must include both internal and external moderation of assessments at exit points of the qualification, unless ETQA policies specify otherwise. Moderation should also encompass achievement of the competence described both in individual unit standards as well as the integrated competence described in the qualification.

    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 115940, "Demonstrate basic knowledge of different types of trenchless technologies in water and wastewater environments", Level 5, 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 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.
  • Evaluation of calculations and recommendations.
  • Case studies.

    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.
