Learning Outcomes

This unit of competency describes the skills and knowledge required to identify design requirements, determine specifications, define pumping and power system requirements, determine capital expense and operating expense budgets, and design irrigation systems. The unit applies to individuals who apply specialised skills and knowledge to the design of irrigation systems, and take personal responsibility and exercise autonomy in undertaking complex work. They analyse and synthesise information and analyse, design and communicate solutions to sometimes complex problems. No licensing, legislative or certification requirements apply to this unit at the time of publication.

Elements & Learning Outcomes

E1Determine design requirements

0310.E1.O1Analyse water quantity and quality needs for a particular crop or situation so that an estimation can be made for sufficiency and timeliness

0310.E1.O2Evaluate water transfer, recharge, reuse and harvesting systems

0310.E1.O3Determine water collecting and storing processes that do not degrade the water quality

0310.E1.O4Determine construction specifications that satisfy organisational and regulatory requirements

0310.E1.O5Investigate regional geology and geography to predict irrigation system parameters

0310.E1.O6Conduct a site investigation to assess type of soil, depth of soil, depth of ground water, soil and water salinity, and structural or chemical impediments

0310.E1.O7Determine the most cost effective irrigation system

0310.E1.O8Document design calculations and decisions

0310.E1.O9Identify and protect environmentally sensitive areas according to local, state and federal legislation and regulations

E2Define pumping and power systems

0310.E2.O1Identify 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

0310.E2.O2Select pump motor combinations that are efficient, reliable, functional, serviceable and flexible for the intended application

0310.E2.O3Determine energy requirements and layout of electricity lines and check with local authorities

0310.E2.O4Optimise the relationship between capital and operational costs including a comparison of energy sources

0310.E2.O5Document performance indicators, design calculations and decisions

0310.E2.O6Design construction specifications that define work required to make suitable pumping and power systems available

E3Design an irrigation distribution system

0310.E3.O1Investigate regional geology and geography so that a prediction can be made on the sustainability of irrigation

0310.E3.O2Evaluate distribution systems and design with respect to a range of key variables

0310.E3.O3Size pipes, valves and fittings according to design system specifications so that capital cost is balanced against operation costs over the anticipated system life

0310.E3.O4Calculate and document flows, water levels and pressures so that they are within the acceptable tolerances for optimum performance

0310.E3.O5Include mechanisms for controlling and adjusting pressure and confirm isolation valves to direct water to areas with different irrigation schedules

0310.E3.O6Design distribution and monitoring systems to meet industry recommendations and calculate distribution system flow and velocity

0310.E4.O3Estimate labour requirements based upon documented work schedule with reasonable allowance for variances in work schedules

0310.E4.O4Base costing attributed to each component on quoted information from suppliers, or sound analysis of individual elements

0310.E4.O5Document capital expense budget

0310.E4.O6Confirm capital expense budget output with an appropriately experienced and qualified person

E5Determine operating expense budget

0310.E5.O1Calculate an operating expense budget that includes all expenses applicable to the completed irrigation system

0310.E5.O2Document operating expense budget
