Measure irrigation delivery system performance

Assessment tool

Version 1.0
Issue Date: March 2024


This unit of competency describes the skills and knowledge required to measure pressure, flow and distribution uniformity of an irrigation system.

It applies to individuals who take responsibility for own work and for the quality of the work of others. They use discretion and judgement in the selection, allocation and use of available resources. All work is carried out to comply with workplace procedures.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)



Evidence Required

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.

Element

Performance criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Measure irrigation system performance

1.1 Measure and record system pressures, water flow rates and pump performance parameters

1.2 Measure variations in system pressures, water flow rates and pump performance parameters where relevant and record

1.3 Inspect distribution and delivery systems and identify and fix malfunctions in system and record actions

1.4 Identify and record factors external to the system that may cause interference

2. Monitor supply of equipment and spare parts

2.1 Record supply and part usage

2.2 Monitor spare parts to ensure the supply meets demands

2.3 Make purchases within budget constraints

2.4 Report parts requirements outside of budget constraints

2.5 Record purchases and orders

3. Record and report system performance status

3.1 Record system pressures and variations

3.2 Record system flow rates and variations

3.3 Calculate and record distribution uniformity and mean application rates

3.4 Determine and record watering depth

The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.

The candidate must provide evidence that they can:

access and prepare data records for both print-based and computer-based data

apply measuring and testing techniques

calculate pressure differentials, flow rates, crop yields, estimated water usage and actual water usage

identify adverse environmental impacts of irrigation activities and take appropriate remedial action

use computers to record and report data

The candidate must demonstrate knowledge of:

environmental impacts of irrigation, using water from any ground or underground source

measuring and monitoring procedures for factors contributing to irrigation system delivery

soil water retention testing techniques

water authority standards and procedures

Assessors must satisfy current standards for RTOs.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
