Description
This Unit covers the process of installing surface irrigation structures and components and defines the standard required to: organise resources for installation work; set out and prepare site; construct earthworks and install structures; prepare beds and water distribution equipment; and assist in commissioning surface irrigation systems.
Notes
Elements and Performance Criteria
1 Organise resources for installation of surface irrigation systems
- 1.1 Materials, tools, equipment and machinery are selected according to the irrigation system design requirements and enterprise work procedures
- 1.2 The construction site for the irrigation system and construction method is identified according to the site and irrigation system plans and enterprise work procedures
- 1.3 Parts and equipment delivered to site are checked according to system drawings and specifications
- 1.4 Pre-operational and safety checks are carried out on tools, equipment and machinery according to manufacturer specifications and enterprise work procedures
- 1.5 Occupational Health and Safety (OHS) hazards are identified, risks assessed, controls implemented and reported to the supervisor
- 1.6 Suitable safety and personal protective equipment (PPE) are selected, used and maintained
- 1.7 Water supply is checked to ensure that it is compatible with system specifications
2 Interpret the surface irrigation plan and mark up
- 2.1 Plan is interpreted and levels are taken
- 2.2 Structures are marked out and earthworks pegged
- 2.3 A clean and safe work area is maintained while installation work is carried out
- 2.4 Tools appropriate to the task being undertaken are chosen and used according to guidelines and safe working practices are employed
3 Prepare and maintain diversion and conveyancing structures
- 3.1 Excavations are completed according to plan specifications and enterprise work procedures
- 3.2 Channels are installed according to the irrigation plan and enterprise work procedures
- 3.3Diversion and conveyancing structures are installed
- 3.4 Structures are tested for configuration, flow rates and capacity consistent with the system plan and according to enterprise work procedures
4 Prepare beds
- 4.1 Excavations are completed according to plan specifications and enterprise work procedures
- 4.2 Beds are installed according to the irrigation plan and enterprise work procedures
- 4.3 Bed surface is prepared with use of roto-buck
- 4.4Field distribution structuresare installed or prepared
- 4.5 The supervisor is consulted and remedial action is taken when beds do not meet the plan specifications
5 Complete water measurement and tailwater works
- 5.1 Excavations are completed according to plan specifications and enterprise work procedures
- 5.2Water measurement structures are installed according to the irrigation plan and enterprise work procedures
- 5.3 Channels and tailwater storages are installed according to the irrigation plan and enterprise work procedures
- 5.4 Pumping equipment, lines and filters are installed for recycling
6 Complete installation work
- 6.1 Earthworks and structures are finished off to plan specifications and enterprise work procedures
- 6.2 The system configuration and capacity matches the installation plan
- 6.3 The site is restored and waste material is removed from the site and disposed of in an environmentally aware and safe manner according to enterprise work procedures
- 6.4 Tools, equipment and machinery are cleaned, maintained and stored according to enterprise work procedures
7 Assist in commissioning a surface irrigation system
- 7.1 Water is supplied from channels or head ditches
- 7.2 Watering sequence is in accordance with organisational procedures
- 7.3 Testing and monitoring equipment are calibrated to manufacturer specifications
- 7.4 System is monitored for watering efficiency, deep percolation and tailwater
- 7.5 Operating faults are identified and corrective actions taken.
- 7.6 Work outcomes are recorded or reported to the supervisor according to enterprise work procedures
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.
Surface irrigation systems may include:
any systems that apply water across the surface of a levelled or contoured area. These include furrow, border and basin irrigation.
Diversion and conveyancing structures may include:
intake structures
diversion weirs and gates.
Field distribution structures may include:
canals
pipelines
drop structures and chutes
division boxes and turnouts
checks
crossing structures
flumes
culverts
inverted siphons.
Water measurement structures may include:
weirs
parshall flumes
cut-throat flumes.

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:
organise resources for installation work
set out and prepare site
construct earthworks and install structures
prepare beds and water distribution equipment
assist in commissioning surface irrigation systems.
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.
