Design 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

Reference books for 'Design water treatment systems' on This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to 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. Determine design requirements

1.1 Determine the quality of water to be treated and level of treatment required

1.2 Develop construction specifications that define the work required to treat water

1.3 Identify and protect environmentally sensitive areas

1.4 Document design calculations and decisions

2. Define pumping and power systems

2.1 Select pumps to treat water efficiently and effectively as required and to enable supply at the flow and the pressure required to operate the distribution system

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

2.3 Calculate energy requirements and determine the layout of electricity lines and check with local authority

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

2.5 Select structures, valves and accessories and integrate into a functional system that can be monitored and maintained

2.6 Document performance indicators, design calculations and decisions

2.7 Develop construction specifications that define the work required to make a suitable pumping and power system

2.8 Check power supply design specification with power authorities

3. Design an water treatment system

3.1 Evaluate and design treatment systems with respect to a range of key variables

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

3.3 Calculate and document flows, water levels and pressures to be within the acceptable tolerances for optimum performance

3.4 Confirm that flows, water levels and pressures are achievable by the pumps operating at optimum efficiency

3.5 Include mechanisms for controlling and adjusting pressure

4. Determine capital expense budget

4.1 Document design calculations and decisions and collate plans, specifications and manuals

4.2 Organise a check of the design output by a competent designer

4.3 Determine and document materials required from plans and specifications

4.4 Estimate labour requirements based on documented work schedule, with reasonable allowance for variances in work schedules

4.5 Confirm that costing attributed to each component is based upon quoted information from suppliers, or sound analysis of individual elements

5. Determine operating expense budget

5.1 Confirm that operating expense budget indicates all expenses applicable to the completed system
