Special notes 1 Definition
Enterprise standards – the standards and procedures set by the client or employing organisation for irrigation system adjustment and maintenance.
2 Refer to Unit 1157, Demonstrate knowledge of sports turf soil water management, for the theory relating to irrigation of sports turf.
Elements and performance criteria Element 1 Describe the principles of sports turf irrigation design and installation.
Performance criteria 1.1 Sports turf irrigation systems are compared with agricultural and horticultural irrigation systems in terms of similarities and differences in purpose and design requirements.
1.2 Irrigation system design is described in terms of the specific requirements for sports turf irrigation.
Range must include but is not limited to – water storage, water quality, sprinkler head spacing, overlap, pipe sizes, pressures, flow rates, precipitation rates, run times, friction losses, electricity, fault finding.
1.3 Installation procedures for sports turf irrigation systems are described in accordance with manufacturer’s recommendations and enterprise standards.
Range must include but is not limited to – staking, trenching, pipe laying, gluing techniques, pipe pulling, risers, valves, control lines, backfilling, line flushing, sprinkler head positioning, pressure testing.
Element 2 Operate and adjust a sports turf irrigation system.
Performance criteria 2.1 Controllers are programmed in accordance with manufacturer’s recommendations.
2.2 Operational characteristics of a sports turf irrigation system are determined.
Range operational characteristics must include but are not limited to – testing irrigation cycle, measurement of quantity of water applied, calculation of coefficient of uniformity for water distribution.
2.3 Uniformity of application is evaluated in terms of sprinkler head spacing, overlap, flow rate, water pressure, and application rate.
2.4 The irrigation system is adjusted for maximum efficiency, in accordance with enterprise standards.
Range uniformity of application, ponding, dry patch.
2.5 Timing of water application is evaluated in terms of efficiency of application and turf requirements, in accordance with enterprise standards.
Range day, night, wind, disease potential, syringing, duration.
Element 3 Maintain a sports turf irrigation system.
Performance criteria 3.1 Irrigation components are serviced during the off-season in accordance with manufacturer’s recommendations.
Range screens, pumps, filters, faulty or damaged sprinkler heads.
3.2 The system is drained in accordance with the potential for freezing and manufacturer’s recommendations.
3.3 Common spare parts are procured and the stock is maintained in accordance with enterprise standards.
Range seals, filters, screens, sprinkler heads, springs, valves, pipe materials.
3.4 Weekly visual checks are made during the irrigation season in accordance with enterprise standards.
Range sprinkler head operation, pipe leaks.
3.5 Faulty heads are replaced or repaired in accordance with manufacturer’s recommendations.
3.6 Leaks are repaired in accordance with manufacturer’s recommendations.
Please note Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
