Elements and Performance Criteria
- Perform pre-start checks for gravity fed irrigation system
- Checks of water, power, fuel and lubricants ensure that all are available and the control system is operational.
- Pumps are primed, if necessary, and gates and controls are open or closed in accordance with enterprise procedures.
- Pipes, system equipment and outlets are positioned and set up in accordance with enterprise standards and OHS requirements.
- Start up and inspect system
- Syphons and other delivery mechanisms are primed and started in accordance with enterprise procedures.
- Start up sequence is implemented in accordance with operations manual and water levels, and pressure built up slowly as directed.
- Pressure at the headworks and control valves is within design specifications indicating efficient filter operation, and water is distributed evenly to the targeted areas with minimal wastage and run-off.
- All malfunctions, leaks, damage to water courses and blockages are corrected or repaired immediately and reported in accordance with Occupational Health and Safety (OHS) and enterprise procedures.
- Head water levels are monitored and maintained.
- If used, pumps are monitored during operation, rubbish is cleared from outlets, and pump is backflushed in accordance with enterprise procedures.
- Irrigation changes are implemented in accordance with enterprise procedures.
- Water reuse systems are checked for clearance and freedom from weeds.
- Shut down system based upon irrigation indicators
- Area is irrigated in accordance with enterprise procedures, and time lag between shut down and end of watering is observed to minimise run-off and deep percolation.
- System components are shut down in sequence in accordance with manufacturer's and enterprise procedures.
- Drainage and treatment systems are checked in accordance with enterprise procedures.
- Tailwater control systems are implemented in accordance with statutory requirements and enterprise standards.
- Irrigation activities are reported and recorded in accordance with regulatory requirements and enterprise procedures.
