- Processes are controlled to maintain performance specified in the irrigation drainage plan
- Maintenance procedures for drainage system structures are developed and implemented
- Operational conditions of the drainage system are identified, addressed and reported according to organisational requirements
- Processes are integrated to improve drainage network performance
- Troubleshoot drainage problems
- A visual inspection is undertaken to determine damaged or broken components and results are recorded in accordance with Occupational Health and Safety (OHS) and enterprise policy and procedures
- Areas being drained are inspected for signs of water pooling and problems are recorded in accordance with OHS and enterprise policy and procedures
- Access to drainage lines is obtained to allow blockage to be cleared
- Blockage is cleared or blocked section is replaced according to enterprise, environmental and OHS procedures
- Drainage line is tested to confirm blockage is cleared from pipe system
- Drainage line is repaired/resealed to permit normal use
