Monitor and control irrigation drainage systems

Assessment tool

Version 1.0
Issue Date: March 2024


This unit of competency describes the skills and knowledge required to monitor and control irrigation drainage systems.

It applies to individuals who analyse information and exercise judgement to complete a range of skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. 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. Assess irrigation drainage and collection systems

1.1 Measure drainage performance

1.2 Measure drainage and tail water quality

1.3 Measure water table depth where required

1.4 Measure soil salinity where required

1.5 Identify and record factors external to the system which may cause interference

1.6 Analyse drainage system data and compare to the performance specified in the irrigation drainage plan

2. Regulate flows

2.1 Inspect flow regulating systems and apply adjustments necessary to achieve discharge requirements specified

2.2 Monitor discharge flows and apply diversions to facilitate repair or emergency

3. Control and operate drainage system structures and processes

3.1 Control processes to maintain specified performance

3.2 Develop and implement maintenance procedures

3.3 Identify, address and report operational conditions of the drainage system

3.4 Integrate processes to improve drainage network performance

4. Troubleshoot drainage problems

4.1 Conduct a visual inspection to determine damaged or broken components and record results

4.2 Inspect areas being drained for signs of water pooling and record problems

4.3 Access drainage lines to allow blockage to be cleared

4.4 Clear blockage or replace blocked section

4.5 Test drainage line to confirm blockage is cleared from pipe system

4.6 Repair or reseal drainage line to permit normal use

4.7 Rehabilitate the drainage site

5. Record and report system performance status

5.1 Record water quality

5.2 Record water table depth, soil moisture and salinity

5.3 Document strategies that minimise negative environmental impacts and maximise positive impacts of the drainage system

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:

apply soil moisture testing techniques

calculate water volumes from rate and depth

clear and refill drainage lines

clear blockages from drainage systems

identify hazards and implement safe work procedures

isolate drainage lines

measure water table depth, soil moisture and salinity

The candidate must demonstrate knowledge of:

principles and practices for monitoring irrigation drainage systems

components used in drainage systems

environmental impacts of drainage systems

isolation processes and procedures

levelling and alignment processes

measuring and monitoring procedures for factors contributing to drainage system performance

soil moisture measurement procedures

types and operational parameters of drains

water quality monitoring methods and techniques

Assessors must satisfy current standards for RTOs.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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.
