Elements and Performance Criteria

1. Prepare effluent plant
   • Select appropriate personal protective equipment and check for operational effectiveness.
   • Use equipment in line with organisational safety procedures, manufacturer’s instructions and environmental protection practices.
   • Set up pumping lines and check for operational effectiveness.
   • Pump treatment solution from mixing tank to effluent line, settling pits and clarifier.
   • Run sludge from clarifier and drain water from sludge beds in line with organisational procedures and environmental protection practices.
2. Distribute water to pasture
   • Set flow rate and pump water to pasture area.
   • Check absorption and pH levels; monitor and adjust flow rate for optimal distribution.
3. Complete operator maintenance
   • Follow organisational safety procedures to lock out equipment.
   • Drain settling pits and clean to collection point.
   • Clean solids from discharge drain and dispose of in line with environmental protection practices.
   • Recirculate water from catchment area to irrigation.
   • Monitor dam banks for weed and vermin.
   • Keep effluent plant area clear of foreign bodies and debris in line with organisational safety procedures.
   • Record and report effluent processing and equipment faults to appropriate personnel.
