EVIDENCE GUIDE

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

identify design requirements for drainage and water treatment

determine specifications for suitable pumping and power systems

design distribution, drainage, storage and treatment systems

design water transfer, recharge, reuse and harvesting systems to conserve natural resources

assess the environmental impacts of the irrigation system to ensure it will comply with environmental protection agency regulations.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.
