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 | PERFORMANCE CRITERIA |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section. |
1. Assess sites for reclaimed water irrigation | 1.1 Identify soil/water interactions and soil properties important for plant growth. 1.2 Identify soil sampling sites, collect samples and conduct soil testing. 1.3 Classify soils using field texture, pH and structure analysis. 1.4 Monitor and determine the water holding capacity of the soil. |
2. Assess quality of reclaimed water for irrigation | 2.1 Sample and test reclaimed water and interpret quality parameters. 2.2 Determine crops suitable for the quality of reclaimed water and site conditions. |
3. Implement reclaimed water irrigation | 3.1 Identify basic features of irrigation systems. 3.2 Operate and maintain irrigation equipment. 3.3 Identify and apply irrigation scheduling options for reclaimed water. 3.4 Produce water budgets using crop factors and climate data. 3.5 Apply irrigation water and collect and monitor tail water or runoff. |
4. Respond to water or soil quality issues | 4.1 Develop irrigation management options to respond to water quality issues. 4.2 Identify and apply requirements and options for soil ameliorants. 4.3 Monitor infiltration and drainage. |
5. Compile reclaimed water irrigation records | 5.1 Compile reports from system data. 5.2 Report observations outside defined parameters for further action. |
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.
monitoring and managing soil
solving operational problems
accessing, interpreting and applying relevant legislation
apply environmental policies, plans and procedures
assessing environmental risks at the work site
identifying soil groups
using safety and personal protective equipment
sampling and testing soil and water
monitoring, operating and controlling reclaimed water irrigation
analysing critical aspects of reclaimed water reuse management relating to the project or site
implementing reclaimed water reuse irrigation
identifying environment, health and safety risks and impact on soil, stock and operators
applying environmental procedures
participating in and contributing to reviews of reclaimed water reuse procedures
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.
key principles of irrigation practices, including irrigation scheduling
key characteristics of reclaimed water
relevant legislative requirements
standard operating procedures
primary agencies involved in drinking water quality management
water quality performance indicators
an overview of the water supply system
water hazardous agents and preventative strategies
community and agency roles and responsibilities in monitoring water quality
best management practices for the use of reclaimed water for irrigation purposes
reclaimed water usage licensing procedures and requirements
environmental, landscape and ground structure of work area
equipment operation, capacity and limitations
effects of weather and conditions on operation of site or plant
interpretation and use of material safety data sheets
Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
