Install devices for irrigation systems


Application

This unit describes the skills required to install devices for irrigation systems. These installations may occur in ground and surface water source irrigation systems.

This unit applies to those working as field and operational staff involved in the installation of water industry metering and flow control devices.

The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.

Those undertaking this unit would work under supervision, while performing routine tasks in familiar context.

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


Elements and Performance Criteria

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. Plan and prepare work

1.1 Apply work requirements for installation of flow control and metering devices in irrigation systems from plans, specifications and instructions.

1.2 Prepare work plans to ensure safety within the workplace.

1.3 Select and check equipment and tools to meet safety requirements of the task and site.

1.4 Select, fit and use personal protective equipment.

2. Install devices in irrigation systems

2.1 Carry out installation of device in irrigation systems.

2.2 Check that installed device meets specifications.

3. Restore site

3.1 Backfill with suitable material, moisture content and compaction to maximise compaction efficiency.

3.2 Restore the site to original site conditions.

Evidence of Performance

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. The candidate must be assessed installing at least one type of device listed in the Range of Conditions. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

identifying and responding to operational problems

producing reports and logs

identifying control system or metering faults

interpreting plans, specifications and instructions

conducting routine inspections, maintenance and servicing of basic metering, flow control and regulating devices

completing relevant workplace documentation


Evidence of Knowledge

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.

impact of the principles of hydraulics on the operation of flows

system layout

lock-out procedures for mechanical and electrical installations

organisational communication systems

effective workplace communication processes

materials handling

environmental, landscape and ground structure of work area

risk factors and potential hazards

equipment operation, capacity and limitations

effects of weather and conditions on operation of system, site and plant

flow measurement principles and procedures

layout and performance of pipes and fittings

operation of control systems


Assessment Conditions

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.
