Description
This unit covers the process of measuring the performance and efficiency of a drainage system and defines the standard required to: identify and correcting system problems; measure, record and report soil moisture, salinity and water table depth to determine system performance and efficiency; apply measuring and testing techniques; record and report system performance; use computers for recording and reporting drainage system data.
Notes
Elements and Performance Criteria
1. Assess drainage and collection systems
  • 1.1. 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.
  • 1.2. Areas being drained are inspected for signs of water pooling and problems are recorded in accordance with OHS and enterprise policy and procedures.
  • 1.3. Measurements are taken with appropriate equipment to determine drainage performance.
  • 1.4. Drainage/tail water quality is measured in accordance with OHS and enterprise policy and procedures.
  • 1.5. Water table depth is measured where required in accordance with OHS and enterprise policy and procedures.
  • 1.6. Soil salinity is measured where required in accordance with OHS and enterprise policy and procedures.
  • 1.7. Factors external to the system, which may cause interference, are identified and recorded in accordance with OHS and enterprise policy and procedures.
2. Monitor supply of equipment and spare parts
  • 2.1. Supply and part usage are recorded in accordance with enterprise policy and procedures.
  • 2.2. Purchases of spare parts and materials are within budget constraints.
  • 2.3. Parts requirements outside of budget constraints are reported.
  • 2.4. Purchases and orders are recorded in accordance with enterprise procedures and systems.
3. Record and report system performance status
  • 3.1. Water quality is recorded in accordance with enterprise procedures.
  • 3.2. Water table depth, soil moisture and salinity are recorded in accordance with enterprise procedures.
  • 3.3. Strategies that minimise the negative environmental impacts and maximise the positive impacts of the drainage system, are documented.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole.
Drainage systems may include:
surface drains

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:
identify and correcting system problems
measure, record and report soil moisture, salinity and water table depth to determine system performance and efficiency
apply measuring and testing techniques
record and report system performance
use computers for recording and reporting drainage system data.
Context of and specific resources for assessment
Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.
