Description
This unit covers the process of operating pressurised irrigation systems and defines the standard required to: read and follow operations manual and irrigation schedules; carry out pre-start checks; operate and inspect the system; measure and interpret flow rates and pressures; identify adverse environmental impacts of irrigation activities and take appropriate remedial action; shut down in response to irrigation indicators.
Notes
Elements and Performance Criteria
1. Perform pre-start checks for pressurised irrigation system
  • 1.1. Checks of water, power, fuel and lubricants ensure that all are available and the control system is operational.
  • 1.2. Pumps are primed, if necessary, and valves and controls are open or closed as directed.
  • 1.3. Pressure and flow testing equipment are calibrated and available as required.
  • 1.4. Other pre-start system checks are carried out in accordance with manufacturer's requirements and enterprise procedures.
2. Start up and inspect system
  • 2.1. Start up sequence is implemented in accordance with operations manual.
  • 2.2. All malfunctions, leaks and blockages are corrected or repaired immediately and reported in accordance with enterprise procedures.
  • 2.3. Pressure at the headworks and control valves is checked against design specifications
  • 2.4. Water distributed is checked for even coverage over the targeted areas with minimal wastage and run-off.
3. Shut down system based upon irrigation indicators
  • 3.1. Water is applied for sufficient time to achieve required soil moisture levels in accordance with irrigation schedule, environmental considerations and allowing for weather conditions.
  • 3.2. System components are shut down and drained in sequence in accordance with manufacturer's specifications and enterprise procedures.
  • 3.3. Drainage and treatment systems are checked in accordance with enterprise procedures.
  • 3.4. Irrigation activities are recorded and in reported accordance with regulatory requirements and enterprise procedures.
