PURPOSE OF THE UNIT STANDARD

The qualifying learner achieving this unit standard in combination with context expertise standard(s) will be able to explain the principles of water demand management, sequence meters, collect and record meter readings and flow data and detect water leaks and illegal connections on a water reticulation system. This competence will enable the learner to provide accurate data for analysis and suggest appropriate remedial action, which will result in the conserving of water and the overall reduction of the cost of water to the organisation. 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.

UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS

1. 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.
2. Any institution offering learning that will enable the achievement of this unit standard must be accredited as a provider with the relevant ETQA.
3. Assessment and moderation of assessment will be overseen by the relevant ETQA according to the ETQA policies and guidelines for assessment and moderation.
4. 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.

UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE

Learners should have a knowledge and understanding of:
1 The importance of a systematic approach to data collection and analysis.

UNIT STANDARD NOTES

This unit standard has been replaced by unit standard 254118, which is "Apply water loss control principles", Level 5, 8 credits.

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
Product sample records / reports

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.
