List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Identify all sources and uses of water in process | 1.1 | Identify and categorise by quality all sources of water external to the site. |
| 1.2 | Identify and categorise by quality all sources of water within the site. |
| 1.3 | Identify all uses of water by process and category. |
| 1.4 | Identify water quality required by each process unit. |
|
2 | Calculate theoretical use of water | 2.1 | Calculate theoretical net use of water for each process unit. |
| 2.2 | Calculate overall water balance for process/site. |
| 2.3 | Evaluate the need for water consumption and water quality by process and units within the process compared to alternative processes/units. |
|
3 | Measure actual use of water | 3.1 | Determine actual net water use for overall process/site. |
| 3.2 | Determine actual net water use for each process unit. |
| 3.3 | Calculate difference between theoretical and actual water use by unit and overall. |
| 3.4 | Identify actual water quality used by each process unit. |
|
4 | Develop strategies for reducing the use of water | 4.1 | Rank units by difference between theoretical and actual water use. |
| 4.2 | Rank units by actual water use. |
| 4.3 | Identify units using higher quality water than required. |
| 4.4 | Develop strategies to reduce water consumption and/or use lower quality water. |
|
5 | Prepare a recommendation for a water use reduction strategy | 5.1 | Consult with key stakeholders. |
| 5.2 | Identify strategies required to meet regulatory or similar requirements. |
| 5.3 | Rank strategies by benefit/cost ratio. |
| 5.4 | Short-list preferred water reduction strategies. |
| 5.5 | Prepare recommendation for improving water usage. |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include the ability, for one or more processes/value chains, to:
identify the range of water quality
calculate theoretical and actual water use by water quality
match water quality to site or value chain needs
consider benefit/cost arguments for different water strategies.
Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to conduct a water use audit including knowledge of:
characteristics of water of different qualities
typical water usage on a site
specific water usages within production or operational processes undertaken by the organisation
‘grades’ of water and typical applications for water of different qualities
strategies and methodologies for determining water quality
strategies and sources of advice for determining impact of changes to water usage or quality with products or processes.
The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
The collection of performance evidence is best done from a report and/or folio of evidence drawn from:
a single project which provides sufficient evidence of the requirements of all the elements and performance criteria
multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.
A third party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.
Assessment should use a real project where a sustainable water use audit is conducted for an operational workplace.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process such as workbooks, written assessments or interviews (provided a record is kept).
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required including relevant workplace procedures, product and manufacturing specifications associated with this unit.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
The assessor must demonstrate both technical competency and currency.
Technical competence can be demonstrated through:
relevant VET or other qualification/Statement of Attainment AND/OR
relevant workplace experience
Currency can be demonstrated through:
performing the competency being assessed as part of current employment OR
having consulted with an organisation providing relevant environmental monitoring, management or technology services about performing the competency being assessed within the last twelve months.
