Application
This unit of competency describes the skills and knowledge required to measure, record and report on soil moisture, salinity and water table depth to determine system performance and efficiency.
It applies to individuals who take responsibility for own work and for the quality of the work of others. They use discretion and judgement in the selection, allocation and use of available resources. All work is carried out to comply with workplace procedures.
No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
Elements and Performance Criteria
Element | Performance criteria |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare for work | 1.1 Confirm the location of the drainage system 1.2 Select materials, tools, equipment and machinery 1.3 Carry out pre-operational and safety checks on tools, equipment and machinery 1.4 Identify work health and safety hazards, assess risks and implement controls 1.5 Select, use and maintain suitable personal protective equipment |
2. Assess drainage and collection systems | 2.1 Determine damaged or broken components 2.2 Inspect areas for signs of water pooling and problems 2.3 Take measurements to determine drainage performance 2.4 Identify and record factors external to the system which may cause interference |
3. Record and report system performance status | 3.1 Record water quality and quantity 3.2 Record water table depth, soil moisture and salinity 3.3 Document strategies that minimise the negative environmental impacts and maximise the positive impacts of the drainage system |

Evidence of Knowledge
The candidate must demonstrate knowledge of:
how to measure a water table and salinity
measuring and monitoring procedures for factors contributing to drainage system performance
positive and negative environmental impacts of drainage systems
soil moisture measurement procedures
the environmental role of drainage systems
water quality monitoring methods and techniques
Assessment Conditions
