Operate and maintain gravity fed irrigation systems

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Reference books for 'Operate and maintain gravity fed irrigation systems' on fishpond.com.au. This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to ntisthis.com for every purchase, so go nuts :)

Elements and Performance Criteria


Performance criteria

Elements describe the essential outcomes.

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

1. Install surface irrigation systems

1.1 Check water supply is compatible with system specifications

1.2 Interpret plan, mark out structures and peg earthworks

1.3 Prepare and maintain beds, diversion and conveyancing structures

1.4 Install diversion and conveyancing structures, channels and beds

1.5 Prepare bed surface with roto-buck

1.6 Test structures for configuration, flow rates and capacity

2. Complete water measurement and tail-water works

2.1 Install water measurement structures

2.2 Install channels and tail water storages

2.3 Install pumping equipment, lines and filters

2.4 Confirm that the system configuration and capacity matches the installation plan

2.5 Finish off earthworks and structures

3. Operate pumps and siphons

3.1 Prime pumps and open or close valves and controls

3.2 Position and set up pipes, system equipment and outlets

3.3 Prime and start siphons and other delivery mechanisms

3.4 Implement start up sequence and slowly build up water levels and pressure

3.5 Check pressure at the head-works and control valves

3.6 Distribute water evenly to the targeted areas with minimal wastage and run-off

3.7 Irrigate area and observe time lag between shut down and end of watering to minimise run-off and deep percolation

4. Measure and interpret water levels, flow rates and volume of water used

4.1 Monitor and maintain head water levels

4.3 Replace or clear blocked inlets and outlets

4.4 Measure and record flow rates and water usage

4.5 Implement irrigation changes as required

5. Monitor drainage and tail-water systems

5.1 Monitor water intake, conveyance and distribution, drainage and tail-water

5.2 Check water reuse systems for clearance and freedom from weeds

5.3 Monitor pumps, if used, during operation, clear rubbish from outlets and backflush pump

6. Inspect and maintain a surface irrigation system

6.1 Record damage and blockages with contaminants by damage type, location and the section of the system affected

6.2 Record and report damaged or faulty pumps, valves, electrical components and computer control systems and take action to effect repairs

6.3 Service water measuring, diversion and conveyancing, and distribution structures

6.4 Carry out vegetation control to keep all system components clear

6.5 Undertake servicing and repair of mechanical equipment
