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
- Registered Training Organisations
- Trying to find someone to train or assess you? This link lists all the RTOs that are currently registered to deliver AHCIRG503A, 'Design irrigation, drainage and water treatment systems'.
- Google Links
- links to google searches, with filtering in place to maximise the usefulness of the returned results
- Reference books for 'Design irrigation, drainage and water treatment 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
1. Determine design requirements
1.1. Water is predicted to be available in sufficient quantity and quality for the particular crop or situation at the time it is needed by the enterprise.
1.2. Water transfer, recharge, reuse and harvesting systems are designed to conserve natural resources.
1.3. The process of collecting or storing water does not degrade the water quality for the enterprise or the environment.
1.4. Construction specifications define the work required to make suitable water available to the enterprise in accordance with environmental and Occupational Health and Safety (OHS) requirements.
1.5. Environmentally sensitive areas are identified and protected according to local, State and National legislation.
1.6. Design calculations and decisions are documented to enterprise requirements.
2. Define pumping and power systems
2.1. Pumps are selected to deliver water efficiently when needed, from the water storage at the flow and pressure required to operate the distribution system to the design specifications.
2.2. The pump motor combinations are efficient and the pumps are reliable, functional, serviceable and flexible for the intended application.
2.3. Energy requirements are determined, and layout of electricity lines are determined and checked with local authority.
2.4. The relationship between capital and operational costs are optimised including a comparison of energy sources.
2.5. Structures, valves and accessories are selected and integrated into a functional system that can be monitored and maintained according to enterprise guidelines.
2.6. Performance indicators, design calculations and decisions are documented according to enterprise guidelines.
2.7. Construction specifications define work required to make suitable pumping and power system available to enterprise.
2.8. Power supply design specification is checked with power authorities.
3. Design an irrigation distribution system
3.1. Detailed topographic survey is conducted or an accurate map is obtained showing extent of irrigation, planting layout, physical constraints and contours with suitable interval.
3.2. Detailed soil survey is conducted at suitable intervals and mapped to show variation in readily available water.
3.3. Water budgets are determined having regard to the evapotranspiration state of the crop/plants, soil moisture characteristics and cultural practices.
3.4. Distribution systems are evaluated and designed with respect to a range of key variables.
3.5. Pipes, valves and fittings are sized according to design system specifications so that capital cost is balanced against operation costs over the anticipated system life.
3.6. Flows, water levels and pressures are calculated and documented to be within the acceptable tolerances for optimum performance.
3.7. Flows, water levels and pressures are achievable by the pumps operating at optimum efficiency and according to enterprise standards.
3.8. Mechanisms for controlling and adjusting pressure are included, and isolation valves direct water to areas with different irrigation schedules.
3.9. Channel systems and attendant structures are designed according to industry recommendations, and channel flow velocities are calculated according to enterprise standards.
3.10. Soil types have been compared for erodeability and suitable fill has been selected for construction according to enterprise standards.
3.11. Construction plans and specifications define work required to achieve the required standards of uniformity and efficiency of water application according to industry standards
4. Design a drainage, storage and treatment system
4.1. Regional geology and geography is investigated to predict sustainability of irrigation and storage.
4.2. Site investigations to assess depth of clay, depth of ground water, soil and water salinity, and structural or chemical impediments are used to determine the most cost effective storage system.
4.3. Predictions of leaching fractions and salt movements are documented, and soil amelioration and drainage management plans are developed.
4.4. The need for leachate interception and dewatering system is determined, and if required, construction specification prepared for interception and collection, water treatment, disposal, and reuse or recycle.
4.5. Drains and structures are capable of carrying the design water volumes and intensities according to enterprise standards.
4.6. Damage from water logging is minimised according to enterprise standards.
4.7. Hydrological calculations predict volumes and rates of surface run-off according to enterprise standards.
5. Determine capital expense budget
5.1. Design calculations and decisions are documented and relevant information is communicated clearly through plans, specifications and manuals.
5.2. Design output is checked by a competent designer against enterprise objectives.
5.3. Materials requirements are determined and documented from plans and specifications.
5.4. Labour requirements are estimated, based upon documented work schedule with reasonable allowance for variances in work schedules.
5.5. Costing attributed to each component is based upon quoted information from suppliers, or sound analysis of individual elements.
6. Determine operating expense budget
6.1. Operating expense budget indicates all expenses applicable to the completed irrigation system.
