Monitor and control irrigation drainage systems

Assessment tool

Version 1.0
Issue Date: March 2024


This Unit applies to irrigation managers in the amenity horticulture and food and fibre production industries.

This Unit covers the process of monitoring and controlling the performance and efficiency of an irrigation drainage system and defines the standard required to: identify and correcting system problems; measure, record and report soil moisture, salinity and water table depth; apply measuring and testing techniques; regulate drainage flows and clear blockages; record and report system performance.

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

Prerequisites

Not applicable.


Employability Skills

This Unit contains employability skills.




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.

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 and correcting system problems

measure, record and report soil moisture, salinity and water table depth

apply measuring and testing techniques

regulate drainage flows and clear blockages

record and report system performance.

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.


Submission Requirements

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.

Required skills include:

Ability to:

identify hazards and implement safe work procedures

apply soil moisture testing techniques

calculate water volumes from rate and depth

measure water table depth, soil moisture and salinity

clear and refill drainage lines

isolate drainage lines

clear blockages from drainage systems

identify adverse environmental impacts of drainage systems and appropriate remedial action

use computers for recording and reporting drainage system data

implement and follow relevant enterprise OHS and environmental policies and procedures

use literacy skills to read, interpret and follow organisational policies and procedures, follow sequenced written instructions, record accurately and legible information collected and select and apply procedures for a range of tasks

use oral communication skills/language competence to fulfil the job role as specified by the organisation, including questioning techniques, active listening, clarifying information and consulting with supervisors as required

use numeracy skills to estimate, calculate and record routine workplace measures

use interpersonal skills to work with and relate to people from a range of cultural, social and religious backgrounds and with a range of physical and mental abilities.

Required knowledge includes:

Knowledge of:

measuring and monitoring procedures for factors contributing to drainage system performance

positive and negative environmental impacts of drainage systems

water table and salinity measures

water quality monitoring methods and techniques

soil moisture measurement procedures

water authority standards and procedures

enterprise policies and procedures

environmental role of drainage systems.

drainage appliances/fixtures/fittings and related

level and align site

types and operational parameters of drains

components used in drainage systems

isolation processes and procedures

levelling and alignment processes

regulatory requirements, codes of practice and relevant enterprise service standards relating to blockage removal, disconnection and reconnection activities

environmental impacts of drainage systems

OHS legislative requirements.

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Irrigation drainage systems may include:

both surface and sub-surface drainage installed to handle water which is excess to plant requirements in an irrigated area.

Drainage system structuresmay include:

surface drains

culverts

mole drains

sand slit

sub-surface traps

pit and trap systems

dune and swale systems

reed beds

water-recycling pumps and baffles.

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.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Measurements are taken with appropriate equipment to determine drainage performance 
Drainage/tail water quality is measured in accordance with OHS and enterprise policy and procedures 
Water table depth is measured where required in accordance with OHS and enterprise policy and procedures 
Soil salinity is measured where required in accordance with OHS and enterprise policy and procedures 
Factors external to the system, which may cause interference, are identified and recorded in accordance with OHS and enterprise policy and procedures 
Drainage system data is analysed and compared to the performance specified in the irrigation drainage plan
