Design irrigation, drainage and water treatment 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
Registered Training Organisations
Trying to find someone to train or assess you? This link lists all the RTOs that are currently registered to deliver AHCIRG503, '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
Books
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

Element

Performance criteria

Elements describe the essential outcomes.

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

1. Determine design requirements

1.1 Analyse water quantity and quality needs for a particular crop or situation so that an estimation can be made for sufficiency and timeliness

1.2 Evaluate water transfer, recharge, reuse and harvesting systems

1.3 Determine water collecting and storing processes that do not degrade the water quality

1.4 Determine construction specifications that satisfy organisational and regulatory requirements

1.5 Identify and protect environmentally sensitive areas as required by local, State and National legislation

1.6 Investigate regional geology and geography so that a prediction can be made on the sustainability of irrigation, drainage, storage and treatment system

1.7 Conduct a site investigation to assess type of soil, depth of soil, depth of ground water, water salinity, and structural or chemical impediments and to determine the most cost effective irrigation, drainage, treatment and storage systems

1.8 Document design calculations and decisions

2. Define pumping and power systems

2.1 Identify pumps that can deliver water efficiently when needed, from the water storage at the flow and at the pressure required to operate the distribution system to the design specifications

2.2 Select pump motor combinations that are efficient, reliable, functional, serviceable and flexible for the intended application

2.3 Determine energy requirements and layout of electricity lines and check with local authorities

2.4 Optimise the relationship between capital and operational costs including a comparison of energy sources

2.5 Document performance indicators, design calculations and decisions

2.6 Design construction specifications that define work required to make suitable pumping and power systems available

3. Design an irrigation distribution system

3.1 Investigate regional geology and geography so that a prediction can be made on the sustainability of irrigation

3.2 Evaluate distribution systems and design with respect to a range of key variables

3.3 Size pipes, valves and fittings according to design system specifications so that capital cost is balanced against operation costs over the anticipated system life

3.4 Calculate and document flows, water levels and pressures so that they are within the acceptable tolerances for optimum performance

3.5 Include mechanisms for controlling and adjusting pressure and confirm isolation valves to direct water to areas with different irrigation schedules

3.6 Design distribution and monitoring systems to meet industry recommendations and calculate distribution system flow and velocity

3.7 Design construction plans and specifications that define the work required to achieve the required standards of uniformity and efficiency of water application

4. Design a drainage, storage and treatment system

4.1 Document predictions of leaching fractions and salt movements and develop soil amelioration and drainage management plans

4.2 Determine the need for leachate interception and dewatering system, and if required, prepare construction specifications for interception and collection, water treatment, disposal and reuse or recycle

4.3 Design drainage, storage and treatment systems to meet industry recommendations and calculate distribution system flow and velocity

4.4 Produce construction plans and specifications that define the work required to achieve standards of uniformity and efficiency of the drainage, storage and treatment systems

4.5 Determine if drains and structures are capable of carrying the design water volumes and intensities

4.6 Minimise damage from drainage, storage and treatment system issues

4.7 Use hydrological calculations to predict volumes and rates of surface run-off

5. Determine capital expense budget

5.1 Document design calculations and decisions and communicate relevant information through plans, specifications and manuals

5.2 Determine and document materials requirements from plans and specifications

5.3 Estimate labour requirements based upon documented work schedule with reasonable allowance for variances in work schedules

5.4 Base costing attributed to each component on quoted information from suppliers, or sound analysis of individual elements

5.5 Confirm budget output by checking with an appropriately experienced and qualified person

6. Determine operating expense budget

6.1 Determine an operating expense budget that includes all expenses applicable to the completed irrigation, drainage, storage and treatment systems
